Marlin 'Micro-Groove' ?
Thinking about getting a fun gun.

A Marlin 336 in 30/30 for close range pig stopping.

Love the way this gun comes to my shoulder and feels so natural and easy to aim (might have something to do with my weird shaped melon).

On their spec sheet the gun is said to have 'Micro-Groove' rifling. 12 grooves as opposed
the the standard 6. Does anybody know what the positives/negatives are over standard rifling in this caliber and if the rifling is finer, which I'm guessing it is, will it wear out quicker?

Cheers...

The only drawback I've ever heard of in regards to micro groove rifling is that you can't shoot cast lead bullets well with it, thats why Marlin went to standard cut rifling for the cowboy action shooting crowd.

Theres a pretty good Talk Forum on the Marlin site you might want to check out for more info. Heres a link.

Talking Head, that's not quite correct. The microgroove rifling is shallower therefore the lead bullet hardness AND the diameter are more critical The proper bullet will work fine.

Thanks, I admit I'm a little sketchy on this.Now that you've reminded me I remember reading the actual facts as you posted. Jim
