What was your load? I have not been able to duplicate the factory load accuracy with any of my handloads.

start at 84 to 87 gr RL 33 for the 127/130 bullets

I've been trying us869, need to mess with my load some more.  So far 92gr has been the best,  right at moa but I need to try adjusting seating and fine tuning charge if I can ever find the time.

What is your velocity with 92 gr of 869?

I'll have to check next time out. I forgot my chronograph last time unfortunately.

Quickload suggests 3400 fps with 92 gr of 869.  That said it predicts the same velocity for 87 gr of RL33 but I get 100 fps more.


Will try 869 tomorrow.  Was 92 a max load in your rifle?

Yes. The issue of handloader magazine listed 94 as their max. I shot 93gr and the bolt was sticky so I backed it off. Using 92gr with COAL of 3.5"  was just under moa at 100yds, need to tinker with fine tuning the charge and seating depth but I have not had time to fool with it as of late.

That's good to know, may have to back my charge down. I'll likely be using factory ammo this fall, it shoots really well and i have 2 boxes. Wonder what charges everyone else is using.
