Bumping this thread, I tried the 155g scenar this year based on this info and other recs for my daughter's first elk. Rifle is a rebarreled 22" Rem 600 Mohawk (nothing fancy, just a shillen from Brownells, standard 308 reamer from PTG). Max load of Varget gave us 2900fps in the summer, which is within a grain of our rifle's pressure limit. I got 100 pieces of Lapua brass, fired all of it, but then used 50 for practice and saved the other 1x fired 50 for hunting. I've only got 4 cycles on the practice brass, not sure how many more reloads it will last. I also tried 168g ELDMs, 168g TMKs, and 165g sierra gameking HPBTs. COAL is limited in this action, no room for longer mag box, so only the gamekings and Scenars allowed for function while seating anywhere close to lands/maximizing powder capacity. SGK velocity ended up about 2800fps, which i also thought was awesome. Both were accurate but Scenars obv have better BC. AB calculator shows 2150fps at 400yd, 2000fps at 500, which is a significant improvement over the SGKs. I want to try shooting over my chrono at 300 but I haven't done it, so grain of salt. She shot her elk 2x at only 85/100yd. One was passthrough, but we recovered a chunk of lead under hide very similar to the earlier pic in this thread. Lost most of the back part of the far shoulder. Her buck was about 85yd also, passthrough as well. He's hanging in a cooler for another week, but I don't think we will get much out that offside shoulder. Neither left any kind of bloodtrail, which I don't quite get yet, but also they only went about 20yds.
All very anecdotal but we're gonna keep using them.
Bang, Flop dead! They are awesome as are the 139 gr .264 ones. I just got back from TX and both the .308 and the .260 dropped turkeys, axis, WT, and pigs with authority.
