Been playing with a Savage Axis in .243 Win. Have it shooting pretty well. Worked on the trigger and got it to a crisp 3.75 lbs. Torqued the guard, tang and base screws. Put on Burris rings and a good scope. Best and most consistent load so far is 40.5 grs. of IMR 4350, CCI 200 primer with the Hornady 87 grain HPBT. What .243 loads seem to work well for all the handloaders out there?
Hodgdon benchmark powder, 75 gr vmax and fed210m primers. 3000ish fps out of a 20"barrel and averaged under 1/2" for 6 3shot groups @ 100yards. this powder seems pretty stable in winter or summer conditions.

This might start you in the right direction if Benchmark doesnt work!
