Ok, so I'm about to load my first ever case. Bullets are hard to find these days, so I ended up getting some Sierra 165gr Game King. I want to load them for my 300 blackout, but I can't find any reloading data for that bullet in 300 blackout. I did however find someone who used a Hornady 150gr FMJ bullet with 16.5 grams of H110. Can I use that info for my start load? I'm just not sure if all I should look for is the weight or if the different bullet make and type matters. You should always confirm any load you get on the inter webs with published data. Mistakes happen intended or not. That includes any loads I may give out. In 300 blk (super sonic loads) I have given up on H-110 with heavier than 150 gr bullets. I had some spooky results with 150 gr Hornady Spitzers with H-110. This was with 17.5 grs of H-110. When I use Lil 'Gun or AA-1680, no problems. I have loaded 165 gr Nosler Blastic tips with AA-1680. Please be safe and use published data. I would advise you to not try your plan. Good luck. eta, I hit the Edit button instead of the Quote button by mistake. So all of the print in blue is my post. dryflash3 |

Go to the bullet manufacturer and powder manufacturer websites and find load data. DO NOT trust the internet for load data. Start low, work your way up in small increments. Check for pressure signs along the way. ETA: when in doubt, call or email the manufacturers of the powder or projectile and ask them if they have data. ETA2: Bullet type may matter depending on it's profile. I haven't loaded for this caliber, just advising caution. |
| I just sent Sierra an email and asked them if they had the data. I did find load data for a 168gr Sierra bullet on this website. It says to use 17.2gr. Since the 150gr uses 18gr of powder I would think to start at like 17.5 or so... That sound about right? |

I saw some last time I was there, but it said it was shotgun powder. Is that what yo're talking about? |
| Just for comparison: Hornady 9th edition for their 165-168 data in 300 BLK with H110 they list a start load at 11.6 for 1400fps to a maximum of 14.9 at 1700fps. For Hornady 150fmj they list 15.9 as maximum for 1800fps. With Lil'gun and their 165-168 grain bullets they list 10.8-14.5 grains with 1700fps max. They used WinSR and Hornady cases tested in a S&W AR 16" 1/7.5 twist. |
