Is there any reason for a 7.62x39 improved

[426nut]

Howdy, I'm new to the 7.62x39 caliber and I'm wondering if there would be any viable advantage to have it reamed out to an improved chambering. Thank you, e.

Kinda...A small 30 cal on a ppc bolt that can run with a 30BR. But, I've been shooting a 30 Major(Grendel) for years now and while the capacity is about equal, the Lapua Grendel brass is way, way better than their(or any that I've found) x39 brass. So not much reason other than x39 brass is cheap and readily available. Just don't hit it hard. The Lapua 6.5 Grendel brass is just as good as their famous 220R brass and is way easier to form. Just a simple neck up from 6.5 to 30.
