Ultralite 6.5 prc and ABLR 142gr

[Fuj']

What is that bullet's exact length, what FPS are you at, and what is your twist rate ??.....
Loads that work with a Proof barrel means nothing without knowing how much throat
is available and how much your jumping that bullet. Did you find the jam point to start ??

For 1.5" groups, it can very well be something else. What shape are the groups generally ??
Any reason you chose the Nosler's ??

+1!

Something I learned when playing with ABLRs is they don't necessarily perform best "in the lands" so don't be afraid to experiment off the lands more than "conventional wisdom" might indicate.

after a lot of failed test ladder results, the guys at the gun shop went back to basics.. took of the suppressor and they grouped straight away. it works out the suppressor wasn’t fitted with a rear support bushing… so all sorted… got a 0.5 moa group to play with.. anyone got any experience of typical jump to try out? test loads look like jut only 0.010” off the lands…. getting about 2900fps with 28.5gr adi2225 (rl 25/retumbo equiv)….
