Home Forums Hunting & Shooting Custom Rifles & Wildcats 300 HAM'R build

Okay, I've been jonesing for a 300 HAM'r and thought I better check in with all the cool kids to get your thoughts on who a good builder might be. To further complicate the situation I'm going to list 4 actions I have that I can use as donors. All are left handed.

This will be a ranch rifle and will sport a 18-20" threaded barrel. it will be suppressed pretty much all the time. Bullet weights will be between 110-150 and will likely be 125-135 most of the time. Barrel twist will be 1-15.

Here are the 4 potential donor rifles:

1. CZ 527 in 223 Rem.
2. Rem 700 in 223 AI
3. Ruger Hawkeye in 204 Ruger
4. Tikka T3 in 223.

What say you?

I don't think I'd be all that excited to build a .300 Ham'r on a short action 700 or uni-sized T3 action. I'm not sure what the advantage would be going with an action that will easily accommodate a larger, more versatile cartridge like the .308 Win.

If I were building a bolt action .300 Ham'r, I'd want an action that's more svelt, like your CZ 527.

If being a lefty wasn't a requirement, I think a Howa Mini would do well.

good points Dan. thank you.

Not one of the Kool Kid's, but...

Agree with Dan... At least in theory, as I've got a 300 Blackout and a 221 Fireball on Rem. Model 7 actions, and the action size bothers me not at all.

I've had a CZ 527, nice rifle & loved the set trigger, but I'm not a fan of extended magazines.

The Howa Mini would be my choice... Not avail. left handed? That sucks.


I've always wondered about the twist Wilson uses on the Hammer (1:15). Surprises me that it stabilizes 150's at Hammer velocities.

I'd go with an 18" barrel for suppressed, just to keep the length reasonable. For a handier "Ranch" Rifle I'd even consider 16.5".

For bullets Speer makes a bonded 150 for Blackout velocities (2,100 - 2,200 fps). Good luck finding any, if you do PM me a link.

Once your 300 Ham'r is a sure thing, if interested, PM me and I'll send you a few Speer 130 FN Game (not varmint) bullets so you can see if they feed OK.

Thanks Jerry. I think I've decided it will be built on the CZ action. The single stack magazine should be able to be adjusted to feed the bigger diameter bullets, should there be a problem.

I have considered a shorter barrel length than 18".
