N/A SLAP slugs?

Well tried the slaps in p3 and raw today. I set my reg at about 135 on p3 with the 26gr slaps was running at 1011 to 1025fps smoking! Sited in for 30yrds held around 1/2” group. At 85yrds couldn’t group no better than 2”. 3-5 mph wind. Hm1000x was all over place 85yrds group 4 1/2”. Raw is running 950’s fps. Thinking bout lowering reg on p3 125. And trying that. Hopefully that will tighten group up at longer range. Any tips? And is it true if you adjust reg on raw it voids warranty? My buddy bought it used from UA. He payed to have it tuned for long range slug shooting. They refunded his money and said it was already tuned for long range. Supposedly shooting 32 or 34gr Zane at 980fps. But we never got over 950fps with 26gr. So if it will void his warranty if we mess with it. Where can we send it to have it tuned? Didn’t expect that from UA!
 
I will give them a go,,, ordered 2 boxes,, test 1,2 ,,,1,2,3, test test
the Zons are useless to me, as they get crooked in the mag and do not feed,, in my SPA P-15 using Carm mags
I do not have a single shot tray to test with and don't use in normal pesting,,,
so I do not know how well they MIGHT perform,,, I gotz no patience for such stuff
I will stick with the 33gr pellets

I have found that slugs don't work well with any magazine designed for pellets, those being the ones with an o-ring around them to hold the pellet in. Even in my Paradigm, the CARM magazines are worthless for slugs for the same reason but the factory mags work great. On the P15 it's the same, factory mags work great, CARM's don't. That's just the nature of the shapes and designs. The energy retained using the 28gr slug at 50fpe, gives me an extra 20y of range (110y) over the 34gr pellet at 58fpe out of my Mrod (90y). This is figuring for 35fpe on target. It is worth picking up a factory magazine and trying the slugs if you already bought them.

I think my Sapsan's reg is about 130bar, hard to tell with that little gauge. I've got the hammer spring cranked in. I'll have time on Sunday the 16'th to play more with it.
