2 weeks in. Ive shown you 16 ot of 16 @ 110 yds earlier. Here is 12 out of 16 w 5 mph from right 182 yds.. Note: small hole top center is mounting hole
I should have used smaller target. 6 in 1" hole.What do you think.

Going on a week and dialing in my 700mm barrel on impact. Found that the pellet speed at 886-890 fps kept the pellets within 1/2” groups at 50 yards for the JSB MkII heavies with a heck of a wind today. Will stretch out to 100 this weekend and report. No destabilization of pellets at that speed which surprised me, figured at around 860 they would get squirrely on me. PL max , valve at 3 and reg at 140

I'm using mark II. @870. I found using the higher fps is ok out to 75 yds. After that especialy past 100 the spirals kick in. I think @ 182 i would be lucky to hit the target .
i finally figured out ( after many variations) that speed is not accracy. The PROPER SPEED is where accracy kivks in.
The fps your shooting is about where the 25g pellets will shoot. I still have my best accracy @870ish.

Wash and measure heads. Likes 6.37. 6.36 changes poi 1/2" have weighed them it's a lot of trouble there are some variances I am going to go back to Weighing them. I'm just finally shooting the way I thought the gun should shoot . Feeling way back in the system.. some guys roll their pellets on glass to Gage the skirt diameters and some guys look at them on a sorting board .the 25g they're measuring 6.38 . My impact doesnt like them. Feels like your shoving in a tight one .
i havent run into 6.38 in the mark 2.
I'm afraid we can all take this too seriously and change this fun shooting that I'm doing into tedious work I don't want that to happen.
