300 Hammer - AR-15 Platform

[rewiltshire]

Well, I will clarify. I give it to a youth shootings sports director, she turns it in for scrap prices and buys trophies for the kids.

Well done!

I don't for a second believe it is 300fps faster than the 300 blackout. There just isn't that much powder capacity in a 223 case.

That claim comes down to a very specific powder which I have seen to be true from non-biased shooters. The only issue (thank you 2020-2021) comes doesn't to components and availability. I big believer in what Bill Wilson develops or supports. I think the 300 HAM'R has its place IF YOU HAVE ACCESS TO THE RIGHT COMPONENTS.

I don't disagree with your last statement. I have rifles that are chambered in very specific cartridges that are not mainstream. I just don't buy into things I feel are overhyped and I believe the HAMR's performance advantage is overstated.

I've got two, an 11.3" and a 16" and they are pushing a 130 hot cor 2319 and 2450 respectively.

I really prefer the 11.3" for pig hunting with a suppressor and thermal. I haven't used them for anything but hunting at nite and inside 150y, I like them better than the 6.8 or Grendel. 300bo was always a little light for pig hunting at nite and especially in the pistol length.

I'm a fan and I used Bill's pet load of 28.2 CFEBLK at 2.170 oal with cci450s and it shot right at 1/2" and I don't need any better so load work up was virtually zero.

Plus, Wilson just makes quality stuff and is good people to deal with.

So people can see a comparison for 16" barrels--- can you post your speeds from 110, 125/130, and 150 gr bullets?

110-2600fps+, 125/130-2500fps, 150-2300fps Caldwell chronograph.

I will disagree. I've hunted with a 308 with a 19 1/2" barrel more than anything else. The performance is so similar that for the game doesn't know the difference. Of course the Hamr depending on load has some range limitations, all guns do and it's best to know them. Since most hunting is done under 200 yards it performance is more than adequate for that.

A little extra, 110 Barnes TSX and a 150 Speer BTSP. Fired into a 5 gallon plastic water container backed by 3 1 gallon water jugs at 100 yards. Bullet were recovered in the second water jug behind the 5 gallon container.

I drank the Ham'r kool aid when it first came out. Bill was selling barrels at a very reasonable price, Starline brass was $29/100.
I loaded up a small batch with Bill's pet load, 130 Hot Cor, CCI450, 28.2 CFE BLK. The 16.2" 15 twist barrel shot 2420fps into 5/8" at 100yds.
It became my woods load for whitetail, replacing a 300Blk that I had been using exclusively for <100yd shots on does. The difference in performance is very noticeable! Bang/flop vs bang/run 50 yds/flop.
It may not hold much more powder than 300Blk, but the extra it does hold makes it punch above its weight class!
Also performs very well with 125 Sierra Pro Hunters and with AA1680 powder.

I'm not sure how that compares to a 16" 308w
I dont load 110"s for it but
125/130's= about 2850
150's= 2650-2700
168"s= 2250
178's= 2490
All from my 16" 308w AR

I can't show apples to apples with a 300bo because I shoot a 8.5" one
110's = 2150
125's= 1985
And 200+ are all sub 1050 on purpose

I wonder what a 8.5" 300hmr would get? Anyone have a 300hmr pistol?

Just for comparison I have Wilson Combat 16" Stainless in 300 Blackout, I'm fairly sure it's a 8 twist. If I remember right, at the time Wilson only had 7&8 twist and my intentions were to only run the lighter bullets. The barrel shoots very accurately! Even though I reload for many calibers, I started out using the Barnes 110 Tac-tx ammo, because I hadn't purchased 300 BO dies yet. These shot very well and chronograph showed good numbers as far as SD. I have since purchased dies and tried my best to mimic the Barnes factory load. All groups shot with thermal optic.

Wilson set out to create a "30-30" that shoots like a match gun. They accomplished that mission.
