1:9( (Re: Early/Old RDB)
Oss/Hx QD 762 w/ Cobalt Kinetics Brake/Mount.
Previous outing used the standard OSS Brake and is pictured for reference.

Shot several guns this trip, Rdb being one of them..

Nice Groups! I couldn't find your previous range report. Did you try heavier grain projectiles previously?

Do you think the weight of the suppressor helped accuracy?

It wasn't really titled "range report" but it really was..It was a post about supressors (and that group was in my batch of 3 pics in this thread).

A long while ago I tried a bunch of rounds made by frontier from 55gr to 75gr vs my minorly modified Ar15..but my top rail came loose during that test, and it was only 50 yards not 100. I might have thrown in another vs my Mdr in 556..This is the highlight reel.

I dunno if it's the weight of the suppressor (which is 1lb 5oz currently)..but I've seen where suppressors can mildly shrink groups.But you still have to bee shooting something it likes or it wont matter.

OK I was just wondering if you were shooting 50gr because you found that grouped the best.

I've only shot 55gr and 77g in my two RDBs, but haven't really sat down on a rest to see if they group light better than heavy or vice versa.

That bullet weigh works with my Rdb ,which does have a different twist rate that the current guns...So your milage may vary.

I've shot alot of different bullets and weight out of mine.I was just glad to see some would bring me around 1.5moa. This combination brought me to an average closer to 1moa.

That makes sense. Both of mine are the 1:7 twist guns.
