Let me start with a shameless plug for the NULA. Wouldn't trade it for anything. It would be the last rifle to go if I had to sell them off.
I am looking for a little advice although I think i am well on the way to having it sorted or if nothing else sharing a little warning to do due diligence and check your gun as always your mileage may very.
I got mine a few years ago, all over the web it says 41-42 grains of N110 max.
I started at 39 grains and the 225 gr XTP and an MMP black. All was well, accuracy great. I tried some 250 gr Barnes coppers and they were CRAZY tight. Set them aside and kept with the XTP.
Several deer and a few years later I went up a size on my scope and when I went to sight in I was all over the place.
So I have got back into "fixing" this. I have changed to 230 gr bulk handgun bullet. Consistant .451 diameter. I have tried MMP black, MMP HPH 24 sabots
All the sabots have the pedals blow off. As I am told this is a sign of over pressure I have backed down to 37grs. (also tried 36.7 grs) Accuracy is OK 3 shots 1 inch @ 50 yards.
but pedals are still blown off the sabots.
I ran them over a chrony yesterday. 230gr bullet
37 grs with HPH 24 sabot @ 1126 fps
37 grs with BBSB sub base and an HPH24 @2782 fps.
I did not expect that speed and this makes me think I am still quite heavy on my charge? Thoughts?
