I haven't dealt with the HAM'R, so it might be all that & a bag of chips, but I suspect that it is going to be a lot more limited as to what bullets you can use with it than the 300 BO or the 7.62x40. As the case gets longer there are fewer & fewer bullets you can use due to bearing surface & ogive length vis a vis mag length.
Personally, I am really liking the 7.62x40. There are plenty of useful bullets for it and I easily get 2,500fps with 125gr bullets out of an AR.
In an AR I would also consider the 7.62x39, .30 American (30/6.8 SPC), .30 Remington AR and the 30 ARX/ARk/Major (all Grendel/7.62x39 variations). None of these are handicapped by having to be useful at subsonic velocities like the .300 BO.
i've had a hamr for a while now. maybe cpl thousand rounds thru it?? shot lots of hogs with several types of bullets. i'm shooting with black hot. buddy is white hot but he's shooting a 6.8
i ran across an inquiry on a blkout site while looking for bullet info. i posted some vids using 130 hot core, 125 pro hunter, 110 vmax and 110 pro hunter. i have some 125 tnt ill try next.

That was some good shooting.

I haven't had it very long. I've only shot 2 deer with it, both using Sierra 125gr Pro Hunters. I've also shot 110gr Hornady varmint SPs, Midway 125gr polytips, Nosler 125gr BTs and Speer 130gr HPs. I have some Speer 125gr TNTs waiting in the wings.
My barrel is a 18" with mid gas and a 12" twist. I wanted a 14" twist, but that wasn't available. I wanted to use WC820 to power it, but WC820 doesn't work with mid gas. I should have got carbine gas. I opened up the port from .094" to, I believe, .105" or .110" with no joy for 820. (Dang, I thought I kept notes.) Now I use 1680 and it works perfect.
The 110s shoot extremely well, I just haven't build up the nerve to shoot a deer with a 110. They hit 2,600fps with ease. (chronographed, not guessed.)
The 125s easily get 2,500fps, except for the Nosler BT. The Nosler's boattail takes up powder space & I can't get any more powder in it without using fire formed cases or a drop tube, etc. I could probably fit another grain of powder in with the flatbase 125s & the 110. That's OK, the Nosler doesn't beat the Prohunter with any relevance until you get past 300yds.
The 130s got 2470fps, again with room to spare.
I'm using a couple Wilson Lancers but now Magpul makes 300 BO mags which would work. Mine work great. I don't need more than 2, so I'll probably never find out if the 300BO mags really work or not.
I like it a lot. Bullets are cheap, cases are free, recoil is light. You can watch bullet strikes through the scope. It's a 30/30 in an AR that is about point blank out to 300. The 125 PH friggin' smoked the deer I shot.
I considered building one to meet our minimum caliber requirments for medium game hunting in Colorado. But I got a smoking deal on a pair of BWH barrels in 6mmx45, so that went on the back burner. Glad to hear yours is working out. . Thanks for the report!!

tried some 125gr speer tnt hp last night. when i was able to hit something, they hit hard. one was a looong ass shot and one was gut shot. both drt. that doesn't happen very often. when i had a pass through, it was a good size nasty wound with stuff bubbling and hanging out.
almost forgot about these. using 110gr spire pt. i figured my buddy had the kill shot in the bag so i went for center of mass to see what they did. of course things don't always work out as planned. i was laughing to hard at where my friends bullets were hitting and it took me a few seconds to get back in the game. they were great killers on a lot of hogs but i think i'm settling on the 125s
