Barrel length affects things greatly as well. My .458 w/ a 8" 1:14 barrel can't shoot 500gr subsonics without tumbling almost immediately, but 400gr supers it eats like (expensive) candy. That short needs a faster 1:10 twist for that heavy of a round.

Especially with even the shortest RDB being a 16" barrel and lots more with the 17" or 20" barrels you're dead to rights: The RDB as a whole is better with heavier grain weights, 65gr at a minimum on the 20" IMHO. Hell at this point I'm considering getting some Dark Horse 110gr to try on my 20" RDB since it's no longer that expensive compared to run of the mill thanks to ammo prices surging so badly.

Thanks for the info.

I find it hates 55g, likes 65 grain bullets

RDB or RFB for the Darkhorse 110gr?

Nothing but XM193 through mine lately, mostly American Eagle, PMC, or Lake City surplus, usually at 25 yards, but good enough to be my HD rifle. Far handier than the AR and quite accurate at those distances. It has never failed, but is usually limited to 40-60 rounds per range trip.

For my RDB, yes someone makes 110gr .223. .223 Remington (110 GR)

Sorry I was kinda offline there, juggling a home purchase and catching up on threads now.

OK..I need some of this...
You shot it? Any difference in recoil?

Not yet in my RDB, home purchase kinda ate up my time to go to the range lately. Should have a chance in a week or so and I'll report back how it goes.

 

[odinforever2000]

Right now..
50gr Fiochhi Vmax

New to the RDB family. My question is if you just so happen to run a few mags @62 grain and have some lose mags of 55 grain did any of you have to make a gas adjustment or was it fine?

Also long as your not going from brass to steel...No.
