What is the Marlin Micro Groove technology all about? Is there an advantage/disadvantage?

Thanks
Tom

All it is is instead of having 4, 5, or 6 deep lands and grooves it has about 15 shallow lands and grooves. The advantage is supposed less copper fouling the disadvantage is that they are picky about shooting lead bullets. However there are numerous rifles with micro groove rifleing that will shoot anything that you put down the barrel.

Basically it is just another type of rifleing. Some think it is great and some hate it. My 444 has a micro groove barrel and it has so far shot every thing I have used just fine.

Thanks. I appreciate the info.

As far as I'm concerned it's 100% marketing hype.....I have never seen an advantage attributed to it......However it also seems to work fine as well.

I think it's "patial" hype...but tne benefits in most guns is so neglible, that it might as well be 100% hype.

Really microgrove started with airguns and was in response to some of the problems the relatively soft lead pellets has with deep rifiling.

That being said it was Beeman marketing with that as well.
