I tried the 195 and 240PB in my encore (50 Cal)but didn't get any real small groups.But useing the sst,sw 200,barnes 195,and 200 xtps it would shoot one hole groups at 100 yds.
It shot the 250 sw and sst well also.
The 200 sst and sw did a number on deer but the barnes I just shot one deer with them and it didn't open up so didn't try them anymore.I sold the encore to one of my brothers before I got to try the 200 xtps on deer but they should work great.
The day my brother got the encore I let him shoot a group with the 200 sst's at 100 yds and he even shot a one hole group.He's one that shoots a gun a few shots just before hunting season.So you may want to try these bullets and loads if you want to shoot a 40 cal bullet.I am taking for granted you have a 50 cal since you said 260 SW(250)
The second target is with the 200 sst and either 100 grs or 110 grs of pyro-select,couldn't remember exact.
Hows the trigger on the pro hunter?The reg encore used to come pretty heavy?
