New Marlin bore diameter

[budman5]

Does anyone have a bore diameter for the new Ruger made Marlins in 30/30?
I want to get some cast bullets coming my way.

I'd slug it before I ordered bullets. It ain't hard to do.

Call and ask Ruger 336-949-5200
Given your location and assumed shipping delay/cost maybe just order .310 and cross your fingers.

Never found a .30-30 that didn't like .310, including Micro Groove Marlins.

Probably anywhere from .308 to .310 I have messured a few brand new .30 cal rifles at .310 a bullet of .311 would be your best choice to order as you could always resize it down if your bore turn out of be a tight one.

Don't worry about the bore diameter. Use the largest bullet that will fit in the neck of the case and still chamber. Usually a .310" will work just fine. I do have one older 1948 Marlin 336 that will take a .313" bullet. I don't think you can order a ready cast bullet larger than .310" and it may be a trick finding them.
Good Luck to you!

Thanks for the help gentlemen. I talked to Ruger and rim rock bullets.

I ordered the .310 sized bullets. Rifle comes next week !
