Great bullets for 300AAC BLK when using PMAGs
By Robert O.

A friend and I set out to work up sub-sonic rounds for the 300AAC Blackout. Graf’s has these interesting ACME bullets, and Hodgdon has load data for them on their website, so we purchased some of each, the 245gr and the 265gr, and set about loading them. Since velocity is fixed at just below the speed of sound, 1065fps or so, depending on elevation and atmospheric conditions, more bullet weight is the only way to get more muzzle energy, so we started with the 265gr bullets. Loading to Hodgdon’s spec, using CFE BLK, the loads are certainly interesting looking. It was not until we loaded the first batch into a box magazine that we saw an issue. The loaded 265gr rounds did not feed properly into, nor out of, our PMAGs. The “squarish” bullet interfered with the front taper of the sides of the magazine, and that taper extends all the way down. There’s a little “bump” on the side of the magazine lip, which is intended to push the rising round more central, to help with feeding, and that bump acted to scrape to coating off the bullets, as well. Perplexed, we tried a couple of other magazines at hand and found the Troy magazines and Mil-spec metal magazines worked fine. They are both more rectangular in shape. We then tried the 245gr bullets, and loaded them to Hodgdon spec with CFE BLK, and voila, they feed into a PMAG perfectly! The 245gr is more tapered, and steps down in diameter outside the casing. So, if you want the heaviest bullets / most muzzle energy for your 300AAC Blackout, and you don’t mind using metal magazines, the 265gr is the best bullet on the market. If you want to load them into PMAGs, the 245gr is the way to go.
Great bullet but...

Bullet is great but it has a real problem loading from the mag in my shorty AR. Mangles the tips every time.
I've tried a couple of things but just can't seem to get it to load without issues. Each time I have to assist it either to close the breech or pick one up from the mag.
Got a ton of these so I hope I find a solution here soon!!
