Anyone have a 450 Marlin with a 14 twist. I have a Steyr bolt action coming and look forward to tinkering with it.
What are you shooting for bullet weights and velocity? Powder recommendations? Think I'll start handloading with 350gr bullets and go from there. Maybe 4198 / 3031 since I have it on hand.
I think you can push 500gr+ through this rifle, though I do enjoy my shoulder in its socket

BLR: Buffalo Bore ammo 500gr @ 1675 fps mv.

No.1: 400gr Swift A Frame & Re7 @ 1900 fps mv.
 
Ruger M77 Mark II .450 Marlin with 14 twist 20" barrel using 350 RN's over 48.0 grains of H4198, basically cloverleafs at 100 yards, bullet hole edges overlapping.

I used H322 in my 45-70 G and 450 M with 300 -550 grers I found it to be the BEST ALL around powder for Velocity and Accuracy. JMO RJ

Hornady has stopped production of .450M reloading brass, they will continue to produce .450M ammo.

Beaks & Brass can obtain .450M reloading brass from Bertram Bullet Co. (Australia) heard it's $65 per 20 ea. https://www.beaksandbrass.ca/

A kind gentleman on this forum pointed me to a dealer that had one box of new Hornady brass on the shelf so that was the start. But yes I second the above - they have brass shipping this month. Get on the wait list asap. Once they confirm it has shipped they will invoice you for a deposit. Clay @ Prophet River may have something coming at some point I would check in with him as well.

Ruger M77 Mark II Stainless, originally a 7 RM, #4 Bob Jury 14 twist tube at 20"... long action for the B&C stock that I had in hand... B&C don't do M77 SA. Initially filed Speer 350 FN's into RN's, but that was a pain... switched to Hornady 350 RN's for better feeding. 48.0 grains of H4198 seems to be the sweet spot... tried from 46 - 50... started getting heavy bolt lift at 50... best accuracy was at 48... so dropped back to that and shot a couple nice bears and backed up a client with a jam at a bad time... gun bearer style.

Very nice. How many in the mag? Scope vxr or 30mm vx3?
A 2-7 vxr would do nicely
