I have a Savage 10G in .243 Win. I just finished load development for the 105 gr. Hot-cor spitzer. Now the Speer Manual No. 13 says that starting loads for IMR 4350 is at
34.0 grs. @2418 fps, and max is 38.0 grs. @2651 fps. The #8 manual says that starting loads is @ 38.0 and max is @ 42.0. So based on that I went with Speers #8 and finally settled on 42.8 grs. of IMR 4350 with a velocity of 3025 fps out of a 22" pipe.Groups measure 3/4" to one inch. Case inspection shows no abnormalities( split mouthes, seperated heads) and primer pockets are tight after 5 loadings.
