308 and equivalent cartridges - but it really received’t possible be advised with the powder makers or have strain analyzed data for it. AA1680 is generally placed among AA5744 and CFE BLK in burn up charge.
I used load data from Hodgdon and Accurate, but my first attempt yielded supersonic velocities. (At my site the speed of seem was about 1,143 fps within the test date.) Following reducing the powder demand, eight of the subsequent ten rounds had been subsonic.
Like the one hundred twenty five-grain Nosler AccuBond, this bullet shipped sub-par precision while in the AAC carbine. I promptly assumed precisely the same bullet set-out issue was guilty, so I also examined it while in the CVA Scout. Group dimension was halved to a respectable measurement of all over 2 inches.
The bullet Just about exploded In the gel block, shredding the main eight inches. Its foundation, capped with a little bit of lead core, penetrated to somewhere around 15 inches but was only with regards to the dimension of an aspirin.
Rifle actions, available by Arm or Ally, serve as the core part for setting up personalized rifles, supplying firearm fanatics with a flexible and high quality foundation to obtain wanted effectiveness and specifications.
The bullet expanded the widest of any I analyzed and pushed to 15 inches, the place it exited the bottom from the block. Inside the gel, it acted just like a superior-velocity pistol bullet, which it can be—Speer developed it to the .30 Carbine cartridge.
Accurate 1680 makes use of the very best ballistic technicians and the very best good quality factors collectively to assure that each gun is healthier served with Accurate Powders.
They've regularly out carried out manufacturing unit loads from my rifles. Hornady one hundred seventy gr Interlock soft stage and Shooters World Buffalo powder, 27 gr. 1950 fps. Tricky hitting and deer dropping. Ive attempted other loads working with Lil’gun and CFE Blk but They only didnt give the groups and effectiveness for me.

That's fairly crappy for your 24 inch barrel, Accurate 1680 but since it's a really quickly powder, I'd guess that It could be significantly less influenced by a short barrel than slower powders like 748, 2230, Varget, or BL-C2. Very same Tale for Accurate 5744. Very quick powder that provides some respectable velocities in 223. I used to be pondering if any person has performed this experiment and has results? Otherwise, and when somebody has an SBR they'd like to check, I've acquired a pound of 1680 on my reloading bench at this time....
