Looks like I'm going to be hunting with a Marlin Rifle chambered for a pistol cartridge. Two types of rifling are offered, "deep cut" (whatever that means exactly) Ballard type, and Micro Groove. Ballard cut barrels have slow twist and MicroGroove barrels have faster twist. Primary use will be with jacketed bullets at highest accurate velocities. Also having good accuracy with cast would be great too. Which would be better?

I have some ideas of wildcat chambering to improve the 200 to 300 yard performance of these, expecially in 41. The 410GNR has caught my eye. Limited bullet selection I know.

Also, I'm not finding my dream gun, which is straight stock with checkering, octagonal rifle lenght barrel (20), and until I get a better idea 41 mag caliber.

Thanks for any help/suggestions/ideas
