I tested these 31.2 this weekend out of my pp impact and at 30 yards they were touching but opened up at 50 yards to 1”. Tried them from 935-970 FPS and that was the best I could get out of them. Anyone else get a different results.
NSA .22cal 31.2 gr slugs

For nsa .22 anything past 25g just doesn't work for me, the better ones are 20.2g and 17.5g.

What barrel are you using? Superior, superior heavy, 600mm or 700mm? Also, for me with a 700mm with superior heavy liner I shoot slugs at @1000fps. I start at higher speeds and step down to see the best grouping.

I’m using the 700mm super heavy barrel.
This barrel loves the 20.2 but I need something with more fpe. I’ve been getting about the same result with the JSB Knock.

Have you tried any other slug makers: Varmint Knocker or Griffin? Also, have you bumped up your speeds to see if it helps then backing off a little at a time.
Tuning is fun but takes time and much trial and error to achieve your end result of power and accuracy. Keep at it and try different ammo as well. I shoot Griffin, NSA and Varmint Knockers and each one is great in their specific rifle/tune but if I try and shoot the VK on the Griffin tune I loose velocity and accuracy and vice versa. Now my Maverick loves the NSA and Griffin's but not the VK. I had a few hundred VK for my MK2 and assumed they would be assume in the Maverick but I was wrong.
Switched over to the NSA and Griffin and everything was great again. Just because the one slug doesn't perform well doesn't mean others will do the same. I saw that it was both the slugs and pellets too but would encourage you to try some different slugs if possible.

I haven’t tried other brand slugs yet because NSA and the JSB Knockout are readily available. Didn’t want to tune for slug that could be harder to find and more expensive. I’m going to bump my regulator to 155bar and try shooting the 31.2 hotter.
