.300 blackout

So on a trip to Colorado I stopped and picked up a Ruger American ranch rifle in .300 blackout. I figured it was cheap enough so why not! After much reading I've come to find that the 110gr Hornady Vmax is a popular and accurate round. I'm hoping to find someone on here that has the most recent Hornady manual, and the load data for that bullet. I could've swore I was able to see it on their website, but for some reason I am unable to find it again.
 
It is a little odd at first to use pistol powder. I mainly use 4227 if I remember right, haven't be able to reload in almost a year. 4227 is mainly what I use in .44mags but it works in my .300BO as well.
 
4227
H110
Lilgun
6280

All pistol powders that work well in the 300blkout. Thats one of the biggest reasons it works SO WELL out of short barreled rifles (~9" seems to be the sweet spot)
 
I just shot a 300BO ladder today using win 296--also a pistol powder. I think the compression thing is relative to the bullet and case trim length--the load data I used said my loads would be compressed--but I know they weren't--partially because I had a longer case trim length and still could chamber the round into my AR pistol no problem. My guess is you could go even longer with the American rifle--so I suspect you'll run into load data formulated mostly for AR COL limitations (which after all is what the cartridge was designed for) but I would view it as just a starting point unless the data specifically says it was from a bolt-gun like the American. I could be totally wrong too. : )

Good point, I may have to call around and see if there is any bolt action load data. I'm kind of wishing I would have just bought a .338, but you can't manouver thru thick woods with a 30" barrel (easily).

I would not worry about it--I'm sure anything that will run through an AR will run no problem through your Ruger. Have you fired it yet? I suspect that minimal as the recoil is in my 7.5" pistol it's a lot less in the bolt action rifle with long barrel. That combination of extremely light recoil and 30 cal pounding within 150 yds or so is what makes the 300 BO such a winner IMO.
 
300blktalk.com Has a whole section devoted to bolt gun loads. Subs and supers. Suppressed and unsuppressed.

I signed up the day you told me about it--like 3 days ago?--but still have not been approved.
 
It like a week before the SHOT show. Im sure everybody is busy as hell getting ready for that. Be patient.

As for bolt gun loads, me experience is this.

I run a Rem 700sd in 300blk. All of my AR loads work just fine. The bolt gun allows me to run my COAL a little longer the max AR length and tweak accuracy a bit. Additionally, not being a gas operated gun, powder choices open up. Stuff that would not run an AR work fine in a bolt.

Mostly that allows for quieter suppressed shooting as the gas pressure can be tweeked
