I hate to admit this, but I usually shoot at pistol targets. Larger bullseyes you know. To be shooting at 1/4 inch bulls, WOW. What kind of cocking lever is that? Does it use set screws?Thanks,Yogi
When you file the front dovetail, how much do you need to take off?Is there enough left to put the globe sight back on?Someday I hope to shoot 1/2 as well as you do! -Y
Ed, I bloviated my bit without asking the ultimate question that I intended to ask. You stated 100+ shots over two days. Does that imply two 50-shot sittings, or smaller batches?I asked the question elsewhere if I should force myself into longer sittings than the 20-25 shots I shoot before things start getting wild. In a way, it feels like a cop out to just walk away for a while. On the other, in that post, people said, basically, "you're allowed to get tired of it, do something else for a bit," which is what I tend to do. I may have as many as four 20-25 shot "sittings" in a day, usually two. And sometimes I will sit and shoot one bull, decide "I ain't got it right now" and quit. When that happens, I do try to diagnose why "I ain't got it," like ate too recently, or ate or drank sugary or caffieney stuff, or just not relaxed, etc.When I'm at a range (paying for it) or other circumstances (like borrowing land or a range where my time is limited), I will force myself to shoot more longer.

It's fascinating to me that I have issues with centering the scope reticle in the center of an open circle! LOL......I find it easier to aim at the center of the number block above circle than trying to aim at the center of the open circles.
Nice shooting, Ed."(..) I've been reading posts where folks were having trouble with their springers holding zero from one hour to the next (much less one day to the next)..(..)".If I remember right, in that case there was a suspicion about temperature effects; equipment stored overnight in the air conditioning and first shots of the day outdoors presented POI shift; then, about "half an hour" later, POI would simply come back to early position..After that, I read this in a serious article - "(..)4.5. POI-Shift The point-of-impact can move with temperature changes. The main reason of this is the different heat expansion of certain rifle/scope parts, but also the pressure changes in a built-in air cylinder can move POI. The trajectory of the pellet changes with the environmental conditions, too (the shots go higher in warm and damp air) but this is not significant. Most rifles change their muzzle velocity with temperature, you should check and reset it from time to time - or you have to know how much is it and deal with it while shooting.(..)"http://www.fekete-moro.hu/bfta-setup-manual/index-en.phpEd, sincerely, I think you have the perfect skills to check this.
Ed, thank you for the information. Even considering the 'right' lubes and seals.., I thought that rifle/mount/scope could also cause some(?) POI shifting with relevant temperature changes. Not necessarily because the fps changes, but specifically due an eventual 'misalignment'. With your tests it seems this is not relevant.
