Need some help and information for a AR build

[Leere]

Hello,
I have a project that I started and I'm not sure which way to go with it, I want to build a 100-200 yard target rifle on a AR platform. I would like to use 100+ grain 6mm bullets with a 24" or 26" upper length barrel with a 1:8 twist. I've read a few articles and would like some advise from anyone on this forum that may have built a AR6mm or knows where I can find help.
I have a AR-15 lower assembly complete and was going to do a 300 black out but prefer the 6PPC cartridge for the 100-200 range.

or 6beggs...more case taper easier extration..i think.....
why fight the trend...mid 60's bullets in a 1/13. 1/14 for 100/200....

I like the 6mm Beggs myself. I'm not sure how it would feed in an AR tho.
I would think it would suffer from the same issues the 7.62x39 does. To much case taper they tend to jam up in the straight section of the AR lower.

I would vote for the 6mmAR or the turbo version

if target work, typically single loaded...so feed is a non-issue....
but then i guess no one told my 7.62x39 ar it was not suppose to feed.....
