Just FYI, the cheap $8 sack of Walmart Chinese tennis balls was very disappointing. They’re a bit under-bore, or the durometer of the rubber is wrong so they don’t obdurate (squish wider) in the bore on firing, or maybe just aren’t fuzzy enough to make a decent gas seal. I might have to try name brand Penn balls or something else. According to tracking, my can cannon is maybe showing up today, two weeks late… but I was at a picnic/shoot with @jrpett last weekend, and we were shooting his. The full size cans went about 100 yards, and the small 8oz Sam’s Choice shorties went about 125 yards. We followed the advice in this thread to load them top-down, and did not have any of them burst on firing. But the cheap tennis balls I brought were crap, and only went 50-75 yards, max. And they were moving kind of lazily for even the disappointing distance they did fly. They weren’t spinning hard or curving in flight like some of the videos I’ve seen. My understanding is that different Walmarts may have different makes/brands of generic bulk tennis balls, so it’s possible ones from a different Chinese factory will fly better. But soda can trap shooting with a Saiga 12s and 10 round magazines is a hell of a lot of fun. So much fun, I can easily see building an event just around that alone. But then again, you could just throw it |

If you handload, you can put a bunch more powder in the 5.56mm blank case. Or you could buy them... there's a link earlier in this thread where to buy blanks of different power; can launching blanks and M200 blanks are basically the weakest, but there's like 2 or three more power levels. I believe M195 grenade launching blanks are the strongest. They WILL destroy soda cans though. Even the X-Products .308 can launcher says it doesn't work well with soda cans at all... as several youtube videos show. You've got to shoot frozen cans or chalk filled cans. And I'm not sure there's underpowered .308 blanks available if you did want to shoot soda can instead. So I'm not sure how useful a .308 launcher is when: A) More powerful launchers destroy cans B) Everything .308-platform is heavier and more expensive. C) I can just feed my cheaper lighter 5.56 cannon more powerful blanks to get the same effect. |

Preliminary sample for testing.
Attached File Three different types of tennis balls, packs of 12oz diet “Dr. Thunders”, and some 8oz regular “Dr Thunders”. I wanted all diet (no sticky sugar for the inevitable “splodey” can), but when you gotta shop at 6am on a Sunday morning your options are limited. I would like to find a type of can that fails about 50/50 when fired tab out. If I can find the right ones, it’ll maybe let me gauge any starting pressure differences between the short and long barrels. I.E. if the cans rupture when tab out 50% of the time in the short barrel, then fail less often in the long barrel in identical circumstances, that’d be a useful data point towards the utility of initial launch tube volume when using “iffy” cans. Then I can also contrast that vs. any possible projectile range differences between the two launcher tube lengths. |

Okay, it rained today and the range was soaked, but we got a window in the evening.
For folks too busy for the minutiae, the long barrel averaged about 10 yards more distance. I have no idea why, but here’s my data... Flat, level, known distance range. Laser verified (Leica) 100yards to the “target” (confiscated roadside spam signage). The sign was used for an aiming point, with the majority of impacts falling to the left of the sign. Conditions: Temp: 89° Humidity: 86% Altitude: 1400ft. Baro: 30inHg Projectiles: 12oz Diet Dr. Thunder 8oz Dr. Thunder 12oz Diet Big K Cola (Krogers brand) Tennis balls from Wilson, Penn, and “Athletic Works” (Walmart brand). Blanks: USGI M-200 Lake City 2012 headstamp. Bulk packaged with no lot # available. Soda Launcher: F5 brand with both 11” and 9” launch tubes. To eliminate as many variables as possible, both launch tubes were fired on the same upper receiver, with only the tube itself being swapped. The same M203 quadrant sight settings were utilized for both tubes. All cans were fired “tab in” for the following results— I first fired a dozen 12oz. cans of Diet Dr. Thunder through both the long and short barrels while playing with range settings on the M203 Quadrant sight. While the maximum distance setting for a 40mm grenade is 400m, that setting did not give the longest distance. It yielded a higher apogee, but range was short at approximately 70-80 yards. Impact distance was not measured, as it was readily determined that the 325m and 350m settings went further. Having a finite number of cans and time, I proceeded with a range setting of 350m for the remainder of the test. It is possible that longer distance may be achieved, but was irrelevant for this test. The goal is to compare distance differences between the 11” and 9” tubes with otherwise identical conditions. Next I fired “groups” of 10 cans on the 350m sight setting from both the 11” and 9” tubes. 11” tube with 12oz Diet Dr. Thunder: group was elongated oval in shape with the long axis distributed parallel to the line of fire. Distance was 105 yards with some going a little further, and some shorter. 9” tube with 12oz Diet Dr. Thunder: group was elongated oval in shape with the long axis distributed parallel to the line of fire. Distance was 95 yards with some going a little further, and some shorter. The cans fired for both groups overlapped somewhat on the edges, but the 11” tube averaged roughly 10 yards longer in distance. Black and green sharpie was used on the base of the cans to preclude mixing them up (Black=11” Green=9”). Next I repeated the test again with 12oz Big K Cola, and the results were nearly identical. We just eyeballed the group centers and measured it with a survey tape, because it didn’t appear statistically different enough to even notice. Next I fired 8oz. Dr. Thunder cans, 6 cans in each group. 11” barrel averaged 118 yards 9” barrel averaged around 110 yards Again the edges of the groups overlapped, but the 11” tube eked out some extra yards. With that done, I proceeded to fire the rest of the cans (both 12oz and 8oz) “tab out” to look for burst cans. I observed no burst cans from either tube with either the 11” or 9” barrels. I wanted to see if the shorter 9” launch tube (having less starting volume under the soda can) would exhibit a higher rate of can failure. As no failures were observed, my data was largely irrelevant. I need to find soda cans that are more failure prone to proceed further on that aspect. Next I allowed my lovely assistant (my daughter) to launch the three brands of tennis balls from the 11” tube. They (almost) all performed similarly with an approximate range of 80 to 90 yards average (350m sight setting). One “Penn” brand ball performed a weird hooking maneuver and was lost in the woods. The balls (expectedly) bounced and traveled further, eliminating the ability to measure them very accurately. I could try again in high grass (to arrest their forward movement), but the observed distances are likely close enough to be called “good”. When firing for the first time, the tennis balls have their “fuzz” scorched off of the back half, and upon further firing this may affect their range as scorching accumulates. We were running out of time at this point, so I wrapped it up and cleaned up the mess. All test launching for this outing was performed using my RCBS “RASS” rest to provide both consistent results, and also to somewhat preserve my shoulder. Pics to follow Set up on RASS Attached File 400m setting took RASS to max adjustments. Attached File 350m sight setting Attached File View down range Attached File Most of the horizontal dispersion was from cans bouncing on impact Attached File Conclusions: The 11” launch tube definitely has about 10 more yards of range, but I cannot explain why, because both tubes place the projectile the same distance from their respective muzzles. I’m stumped on that one. I would have guessed the distance to be identical, or perhaps slightly more for the shorter tube, because the projectile starts closer to the blank barrel. I also have no idea if the shorter tube will experience more or less failures, because no can failures were observed. If anything leaked going down range— it was too little for us to see it. |

Took my F5 can launcher out to the range this weekend. I realized that Jeff apparently sent an extra bag of blanks along with the one I ordered for my shipping troubles. Thanks man! He really does have great customer service!
With tabs down I didn't have any failures of 12oz cans in the tube and they were consistently going somewhere close to 80 to 100 yards (I wasn't very consistent with aiming). Some of the best sprays were when I accidentally hit high overhanging tree branches. I was surprised at the failure modes of the cans on impact on packed, wet, clay dirt. It was about 50/50 either rupturing down the entire side or the top tearing completely off at the neck. Might have just been the Diet Pepsi cans I had. Overall I'm definitely happy with the purchase at $150. Might not have been $310 worth of fun, but I'll certainly get $150 worth out of it! For anyone looking to buy I'd recommend spending the extra $9 and getting the version with the rail. You don't need a VFG but it couldn't hurt to have the option. I got a stupidly cheap PSA lower and LPK to put it on and built a BCG from cheap and free parts so I think all-in I'm at about $250 for the whole stand-alone unit, although if I was really concerned about cost I could have just swapped it out with the upper on my AR. @SkilletsUSMC I was shipped an 11" version without asking (probably just what he had sitting around when he rushed mine out the door, and it seems I got the better version so I'm happy). Mine has a total of 4 holes in the barrel nub equal distance along the barrel length in an X configuration - it looks like they made 2 hits with a drill press all the way through, 90 degrees rotated apart, same distance along barrel length. |

@Variable556
Excellent writeup! I noticed you said your quadrant sight achieved max range at the 350m setting. Though I'm not sure how well that will translate to my leaf style sight. Did you happen document any angles of elevation corresponding to particular distances when firing 12oz, 8oz, and/or tennis balls? Or could you calculate the elevation based on your mounted sight? For example, the necessary elevation for 50, 75, and 100 yards... I would think it would be pretty easy with smartphones nowadays. Just lay an iphone or whatever on the barrel before the shot and record the angle using a compass app. |

I only plinked random settings while “breaking the tubes in” () , but starting at 400m was way too high and 350m seemed at least close to max with the 12oz cans. I then just used that setting for everything since I was mostly there to compare the two launcher lengths against each other. 400m comes out to around 42°, and 350m on my M203 Quadrant sight places my launcher’s bore at about 32° elevation (per my phone). There may still be some range left to be squeaked out with a little fine tuning, but that was close to optimal for the specific conditions I tested in today (now yesterday). Hope that helps at least somewhat. |

I wonder if one is wanting to get more range if it would be possible to make some wood disk with a hole bored in the center to slip down pass the barrel. Somthing dense taking up that extra expansion space could increase the pressure behind the can making it fly farther.
Also if anyone has a extra F5 can launcher they would be will to trade for a used RCBS rock chucker + cash IM me. |
