I absolutely HATE energy numbers when it comes to talking bullets/ballistics.
For those GD’ers who never took physics, the formulas shake out like this. PE = mgh KE = 1/2(m*v^2) (KE = PE) One half mass times velocity squared. I prefer power factor which is basically momentum, bullet weight in grains times velocity in feet per second. It usually gives some number like 120,000 to 350,000. Everybody just drops the last 3 digits on the right. |

Quoted: It is a SIGNIFICANT improvement, ballistically, over the 55 and 62 grain offerings. Heck, you tube has tons of "gel test" vidoes showing how mucb mkre effective the 70+ grain loadings are. View Quote In comparison to what. 77 HPBT is going to do great compared to M855 green tip. But how about Barrier blind performance 62-64 loads like MK318 Mod 1 and Fusions? Speed kills. |

My most accurate load, that I shoot out to 600 yards, is a 77 Nosler CC with 22.5 grains of IMR 4895. Not the speediest load, but will shoot 3/4 minute at 100 yards consistently.

Quoted: Energy is a useful predictor of what might happen when bone is encountered. I'm not obsessed with exit wounds but I do appreciate them. I had a very hard time getting exit wounds on 200lbs deer. If they don't strike bone they would get caught by the offside hide. The tmk is a good bullet but it's also not great from a 20" barrel inside 50 yards. View Quote It drives me nuts that people will argue for small caliber and/or cup and core bullets for large game, and make the the statement that “bows kill with very little energy.” Then in the same vein argue that traditional metrics of good bullet performance like weight retention, reliable, controlled expansion, and straight line penetration to an exit wound aren’t important. Completely ignoring the fact that bullets and arrows ultimately kill in the exact same manner (massive hemorrhage due to blood loss) and what makes arrows efficient at killing with very little energy is complete penetration of the vitals with a sufficient sized straight line wound track. Experienced archery hunters, especially those after big game like elk, have learned that they want a heavy arrow that will bust through shoulders and come out the other side with a large enough hole to cause sufficient hemorrhage. Yet somehow those lessons seem to be lost on a lot of rifle hunters. Talk to any archery elk hunter who got caught up in the “speed” craze of the 90s and were flinging light arrows at elk with often poor results if shots weren’t perfect. |

To answer the OP, it's not a different class. It's just the upper end of the spectrum of ammo from what is most common (55gr fmj). It's roughly 25% heavier, and slower, which has a decent level of benefit for certain applications. As for the hunting nonsense. I shot an Elk last year twice with 180gr .300 Win Mag, 180gr bonded bullet, 3,000fps muzzle velocity. Textbook shot placement. Zero exit wounds. It reminded me a lot of killing a small doe with 5.56 a few years back with 75gr Hornady Tap. Textbook shot placement, no exit wound. I would not choose to use 5.56 for anything larger than small deer or pigs. Sure it could work, but it might not. The bones, fat and hide of larger animals are significantly different and harder to penetrate than smaller game. |

Quoted: When rounds like the 6.5x55 and 30-06 (30-03) were interdicted they had extremely heavy for caliber bullets. 220gr for the 30-03 and 162 for the 6.5x55. They remained this way for a bit until they started to really pick up steam with hunters and lighter bullets were introduced. Are the 77gr+ loadings for the 5.56 the same but in reverse? I’ll admit, I’ve been shooting 223 and ARs for more than a decade and never shot heavier than 64gr soft points. I still am working through my stocked up crap Russian 55gr 223 for range ammo. 55gr has almost been my only weight for the entire time. It’s fast, cheap, and good m193 is easy to both train with and keep loaded in my kit (though that’s mostly Federal 64gr soft points with the same POI as m193). I have ARs in 10.5”, multiple 16”, and an 18”. All are 1:7 or 1:8 twist. Am I crazy for not trying out 77gr ammo, especially to keep in my HD mags? I shoot my ARs a lot and always have felt a different POI would be a big bother between my practice ammo and HD ammo… View Quote I think your idea is correct but i would not put 77gr .223 in the same class of "heavy for caliber" bullet as defined by sectional density. Rather I would say that going from 55gr to 77gr is going from very light for caliber to medium for caliber at best. 77gr .223 SD=0.221 psi 162gr .264 SD=0.332 psi--0.221 would be 108gr 173gr .284 SD=0.306 psi--0.221 would be 125gr 220gr .308 SD=0.331 psi--0.221 would be 147gr 286gr .366 SD=0.305 psi--0.221 would be 207gr 350gr .375 SD=0.356 psi-0.221 would be 218gr 500gr .458 SD=0.341 psi--0.221 would be 325gr SD is a good indication of penetration and 77gr .223 looks like the light end of usefull loads for those other calibers intended for thin-skinned game. |

I prefer 75gr Gold Dot and BTHP. I will admit that 77gr TMK is an impressive fragmenting round and better for unobstructed shots than the Hornady BTHP.
I am not a big fan of 77gr SMK/Mk262 yes I know it’s a much more accurate round at range vs the Hornady BTHP but it’s inconsistent with its fragmentation. |

I shot my first deer, a large doe, with 75 grn Hornaday tap at 373 yards out of a 20" AR. The bullet entered just behind the left shoulder crease and punched a quarter sized hole in the opposite side crease. Liquefied both lungs. DRT.

THREE TIMES THE ENERGY at 600 yds. Huh. If you'd like, we can discuss Ballistic Coefficient. But it involves more physics. View Quote I totally agree with you on physics not being able to be bent, however when shooting live targets (deer in my case) bullet selection is makes a huge difference. Ballistic coefficient, terminal performance, and starting diameter allow certain cartridges to perform better than cartridges with similar paper specs For example, I have 2 357 rifles (Ruger 77/357 and Marlin 1894). The 357 Mag rifle puts deer down fast and reliably because of it’s bullets design, not it’s energy. The new generation of PRC and Creedmoor cartridges dictate a tighter twist and therefore allow heavier bullets than similar cartridges (ie 243 Win vs 6mm Creedmoor). This is still physics but taking a 243 Win and putting a 1:8 barrel on it would make it “punch above its class” when compared to a standard 243. |
