Got my RRA NMA4 in today. Pretty dang excited about it. I just sighted it in for 200 yards and there are two local matches tomorrow, so all is right with the world. I had an experienced shooter at one of these matches give me a recipe for 52gr Sierra Matchking with Win 748. After shooting 55gr and 77gr bullets today (things I had on hand) I have high confidence in the 52gr performing very well.
First question to the forum: Does anyone have a recipe for 52gr Sierra Matchkings using 8208 XBR? What about with TAC? My gun is (NMA4) 20" bbl with 1:8 twist, and I am looking for a sweet spot to focus on when I work up my load (following Sierra's manual).
(I have 8208 and TAC on hand, so was hoping to get loads with those powders in addition to 748.)
Second question: I picked up a leather sling at the fun show today and it is raw leather. What oil or other substance do you all recommend as the best to condition, protect, and break in a new sling?
I may ask the reloading question in that forum, but I wanted to get input from high power shooters first. Any suggestions on what has worked for you all (or what to avoid) would be very helpful.
