    Title says it all. I am looking for the best bullet weight for my new 300 blk 8.5" barrel with 1:7 twist. Looking to only shoot supersonic unfortunately because I cant own a suppressor in IL.

    What are you looking to do?

    If looking for a hunting load I would recommend sticking with the 110g monolithic options or up to 125g but not above.

    For target shooting I’ve found the 150g bullets seem to come cheaper than others when buying ammo, but aren’t very good as far as terminal ballistics. If reloading then the 125g tnt bullets are pretty cost efficient and shoot great in my 10.5”.

    I literally just stumbled upon the TNT's on sale https://www.midwayusa.com/product/2149663126. I may try them based on the price I don't think I can go wrong. I will be using them mostly for target shooting maybe some varmint down the road.

    Thanks

    they are good bullets. If looking to take game, and take advantage of a bit flatter trajectory, try the 110g gmx bullet. It’s not cheap, but I’ve personally witnessed its performance on east ky white tails and it’s great. My 9 year old daughter hunts with it and took a good sized 7 point last year. Full pass through, lung shot.

    Not sure how it will run in your rifle as mine is a 16" 300 BO but I have had awesome luck with 110 gr 30 carbine style bullets at 50-100 yards accuracy-wise. Beyond that I cannot say since I haven't shot it that far yet. The 125 TNTs are as has been stated awesome and if you can find them in a reasonable price so are the Nosler 125's.
    I stumbled on the 30 carbine style bullet because I have about 500 and was only using them in my 30-30 WCF contender barrel for plinking loads. loaded up some with 19.5 gr of 4198 and WSR primers. clean barrel, little to no residue in the barrel and groups that made me grin.

    Defensive use, I load Nosler 110 Varmegeddon"s, which react although varmint bullets differently at .300 AAC MVs. In my 9" Faxon Barrel I get 2170 FPS:

    he reads his standard tape and says “12.2 inches”. That’s embarrassing as a man.
