I "think" the burping problem is gone. At least is was today but there's more to the story.
It was 37 degrees out when the problem happened last Friday, and the battery was one bar down, also the dwell was set at 20. Could all those combined caused the burping, who knows?!
Today I let the EVO sit in the sun for 20 minutes, it was nice out in the low 60's, with low wind, and not a cloud in the sky. I didn't recharge it yet. While setting up I called Darryl at Skout and explained what had happened last Friday. He suggested upping the dwell between 23 and 28.
But first I wanted to see what would happen shooting the gun without any changes. The gun worked fine??!! Nevertheless after that I set the dwell to 28 for this shooting session but the EVO was shooting higher velocity at mid to high 840's so I decided I'd experiment with the regs again. I brought the LRP up to 155 psi and brought the HPR down a tad to achieve the 829 ave velocity which took a while turning each one to what seemed a good balance between the two. I can't tell if it shoots any better or worse than before but I didn't have any problems??
Once I rezero'd bringing it up .1 mil at 34Y I shot 3 shots in the KZ, went to 45Y and shot 3, went to 64Y and shot 3 more and all those landed in the 1.25" KZ. Repainted, went to 72Y, with the wind picking up, and finishing off what was left in the mag, missing some and hitting some. As you can see the vertical isn't too shabby for off a tripod.
But I'm glad I didn't have to send the gun back.
The low shot that didn't get painted well was from last Friday when I was trying to figure out where the wind was pushing the slugs to. It seems that with a 5 mph left to right quartering wind the down range wind isn't doing what my wind estimation of hold off thinks it should be so I hit left anyway. I need to put some wind flags out and see what up. Even so I would have missed only once on a 2.5" KZ.
Now to start practicing off the bipod that I use for FT.
I changed the scope to a 2nd Gen Vector Continental 5-30x56 because the Meopta Optika 6 doesn't parallax focus below 25Y and thought I'd be fine but NOPE. Man the IQ leaves a lot to be desired in the Vector compared to the Meopta so I'm going to change over to a higher end scope instead. Might just go for it and put my March Genesis 4-40x52 on the EVO because it'll add more weight to steady the gun, and the IQ is awesome, plus no concern for running out of elevation travel at ELR distances.
