[QUOTE="nralifer, post: 2690986, member: 94556"] I might sound like a broken record, but I would try StaBall6.5 with the 196BD2 from your 20” WSM. The BC and penetrating abilities of that bullet are so good you don’t have to worry a lot about speed, but start with 53 gr with a 0.025” jump and in 5-6 shots you will arrive at your load if you use 1 gr increment increases and watch for early pressure signs. My guess is you can reach 2800-2900 without too much trouble. With a G1BC of 0.675 and a minimum impact velocity of 1700 fps you will outperform anything you have used thus far and be good out to 900+ yds at sea level conditions at 2800 fps. Using the SB6.5 in my 26” 300 WSM and the 25 ft/sec/inch rule I get 3200 fps from our 175gr BD2 which translates to 3050 fps from a 20” barrel. I have found that SB6.5 is quite temp stable and compresses extraordinarily well without any erratic behavior. [/QUOTE]
