I shot these groups from my Crown Continuum in .22 and .25 INDOORS in an un-airconditioned warehouse with NO discernible wind at exactly 100yds(range finder and measuring wheel). I locked the Crown down in a gun vise and carefully squeezed off each round, shooting 5 shot groups at the same aim point from 250 bar until the regulator pressure got down to 160 bar.
After much trial and error testing, I have settled in on a reg pressure of approx. 145 bar which allows most flexibility(for my shooting) with multiple barrels/pellets/slugs vs shot count. Preparation included cleaning barrels with patchworm then firing 50 pellets, then refilling to 250 bar. I didn't sort any of the pellets, except for looking out for bent skirts. I loaded 10 pellets in the magazines at a time, then shot 2 targets then reloaded the magazine.
JSB .22 18g set up:
Valve setting- 177/22, Power wheel- 4= ave. 940fps
JSB .25 25g set up:
Valve setting- 177/22, Power wheel-5= ave. 895fps
If I had shot these OUTDOORS, I would have thought I would have thought wind must have gotten to some of these groups, or I must have "pulled" some of them. But there was no wind and the Crown was locked down in a gun vise.
I have tried many other setups/combinations/pellets, but I'm sure I haven't tried them all. For now, this is as CONSISTENTLY accurate 100yd setup as I can make it and I am probably going to move on to the next phase of learning how they perform outdoors in the wind and how to "score" well. Any analysis, input, questions, or suggestions will be welcome.
