I use RL17 with Berger 140 VLD hunting bullets in a 7-08 . this rifle has a 24" bbl . the last five shots through my chrony 3077, 3077 , 3080 , 3077, 3081 . I have not noticed temp sensitivity , but I keep reading about it . RL22 has a bad reputation for this so I think it's just being pinned on all the reloader series powders . when reloading components get easier to buy I'll try RL17 in my other 7-08 with a 139 BTHP , to see if I can increase the velocity without loosing the accuracy . I think you will like it , I do .

I used (rl17)it at someone elses suggestion with the 150 ablr with great results. I also really like rl19. I've shot a bunch of sst and other hornady bullets, they are ok but I switched to AccuBond 140 and never looked back. Remington 700 bdl with no alterations in 7mm08
