    RF reamer for sk ammo

    Traditional BR chambers with .100 or more engraving length are usually cleaned after each target. Position shooter typically clean at greater round count intervals. I suspect the lighter engraving is more suitable for extended cleaning intervals. Probably related to carbon ring build up rate.

    RF reamer for sk ammo

    With your ".660" depth, what is the stick out dimension from the back of the rim to the barrel or from the front of the rim to the barrel?

    What is a "State of the Art" RFBR rifle

In benchrest, the thinking is you want the slowest twist that will stabilize just enough to get to the target. 14 twist used to be the norm in short range CFBR and now it is 13.75. 16.5 is the norm for 50 yd RFBR.
