Does anyone have loads for 150 gr projectiles? Books show less than what 162's do so not much help. I have 2217 and 225. Looks like about 1gr less for 2217. Will be using 150 bt's , lrab's and eldx's. Will also load 160 tmk's as they shoot the best so far which I use 225 for but if 2217 is better for 150's I'll load some with that to keep the test the same. My rifle can go to 74 grs of 2225 without pressure signs and usually uses 73-73.5 with 162's
Rule of thumb is 1gn of powder for every 10gns bullet weight so you SHOULD be right increasing your 162 loads by 1 grain (but I would start at the 162gn load).
I am using 70gns 2213sc with a 150gn BT if that is any help. Way over book max but no pressure signs what so ever.
