About five or six years ago I started shooting in the local milsurp matches(about 25 guys) most were shooting service rounds or loads with nosler custom comps(27 cents a pop), I was the one shooting cast.
I started out using the old standby 16 gr of 2400/4227/4759/5744 and even wc-820 with 311299/314299 and 316299 in 03a3,m1914,k-31and smle, well I soon got tired of feeding gas checks to all of these and switched to plain base and my scores didn't get worse and some of them got even better(I keep all my targets).
Nothing will weed out bad groups as good as five consecutive ten shot groups every time you shoot, i found out when you get close to 22 or std vel speed (1050 to1200 fps the group are better (five times in a row), I have never never beat all the jacket guys, but I've beat a bunch of them, score run from high 280s to mid 290s, some of those guys shooting nosler c/c shoot 298 and 300, but it's lots of fun
