.429 GNR

[pacecars]

Since I can’t leave a perfectly good rifle in a perfectly satisfactory chambering, what experience do y’all have with Gary’s .429 GNR? I am thinking about a rechamber of a Marlin 1894 SBL .44 Remington Magnum

Ronnie, definitely takes more than a rechamber on that one since the 454 Casull Brass is considerably longer than 44 Magnum.

But, it's definitely a good conversion. I've had one a good many years. About 250 fps faster than a 44 Magnum...

I’ve had a 429 GNR since 2008. It’s a great cartridge.

Waterboy has a 429 GNR lever action carbine that started out as a 44 magnum. It’s a super sweet little rig.

I had one as well. 5” barrel that for me did not do it justice. Just remember, if you load H110 you’ll need to fill the case! I can’t tell you how many times I’d disassemble the gun cause I’d get a squib at 28gr or less! Bullet in barrel as well.

Settled on 31gr and all was well.

It's a big job getting anything to feed in a pistol caliber levergun longer than 1.600", Rossi's 454 model 92 will potentially feed longer than 1.800" depending on the specimen and bullet profile.
McPherson has a levergun book detailing very invasive work done on Marlins to feed long cartridges.
My 2 cents is that the 454 Rossi or a model 92 generally is a better wildcatting platform and stronger.

The pragmatist in me says, buy a Rossi in 454. But it sounds like a nice conversion and I do like Marlins.
