When my wsm had a 21 inch barrel I was using 62.9gr of rl17 and averaging 2900 ish with the 178 eldx, but couldn’t get mine too group under 3/4 inch consistently. Barrel is now 19 inch and using 178 eldm with 60gr of rl17 is getting me 2660 and same hole groups for a bush sika load. Will do a hotter one for when the long range missions start up.
