Home Forums Reloading Big Game Rifles .257 Roberts fav's

Favorite loads in my Roberts are the ones that shoot well enough to suit me. So far 117-120 grain BTSP's and 42.0 grains of IMR 4350 popped with CCI 250 magnum primers is where my Ruger likes to be. Just ordered some on sale Speer bullets from Midway and just got done testing them. Worked up looking for pressure signs stopping at 43.5 grs. of I4350 with the Speer 120 gr. Grand Slam bullet. Loaded ten with that bullet and put all in 2.5 inches, not good enough. I also ordered some 120 gr. Speer BTSP's to test, loaded ten with 42.0 grs. of I4350 and put them all in just over an inch. Went back to the Grand slam bullet trying the same load and got all ten in just under 2 inches. Still need to do some work with that one. The rifle really likes the 100 gr. Speer hollow point and both Hornady and Sierra 117 gr. BTSP's. Nice day out after the race, might just load ten more up and see what happens.
