OK,49.5 IMR4350,all things same except just a small tuft of dacron, ruined a 5 shot group.Whole group wanged... and this coming from a guy who really likes dacron fillers. That was yesterday,bummed me out thinking previous efforts may have been a statistical issue.So back to no filler 49.5.
Today,5 shots as fast as I can load/shoot/jack/repeat.First 3 cloverleafed in the X,cold bore.#4 opened group to an inch,#5 wanged to open group up to 1 1/2".
So,ice the dacron,49.5,and rip 3 shot groups.Will continue over the next few days confirming,and dialing in dope,and looking for Mr Ghog.
Thankyou,thankyou,for the help guys!
