I load 140gr SGK’s over RL15 and so far no problems even though Ive read (on here) about all the Sierra bullet disasters people have had. Shoot 165gr in my ‘06 and 65gr in .223 with same results.
I have several hundred old, 50+ years old IIRC, 120 grain flat base Sierras I got as part of a bulk deal a component supplier of mine got out of an old stash. I put a bunch of them on top of a stiff charge of Varget since I had a good bit of it. RL15 would have done just as well. My buddy shoots them out his 7mm08 Model 7 and he had no trouble with the does and pigs he popped. Also for many years my father shot 150 grain boat tails out of his 30-06 for deer. 52 grains of IMR4064. One shot, one deer, no problems. This last season I killed a number of pigs one shot apiece with 100 grain Game Kings out of my 250 Savage.
