Picked up some RL 17 for hopes of some more velocity and great accuracy. Loaded up some rounds to shot a ladder In my tikka t3 24 3/8" barrel. To my surprise velocity was far more than I was expecting. My ladder charges were 63 @2953, 63.5@2994, 64@3019, 64.5@3041, 65@ 3084, 65.5 @3079, 66@3113, 66.5@3134, 67@3177 and 67.5@3205. These charges of powder with nosler brass, 215 primers and nosler 180 ballistic tips was faster than I had expected from this barrel length. Anyone looking to load this powder should know that 66 grains is recommended max. And as always start low and work up. I'm my gun even at 67.5 only had light marking on case, primer was not flatted at all and no stickeyness in bolt trying to find max load for this particular gun. Not sure if the accuracy will turn out as good as I had hoped for, but did have a decent node between 64.5, 65 and 65.5 I will try to exploit in near future.
