6.5PRC 156 berger - seating depth OAL/jump

[mauiarcher]

working up a load for tikka t3x 24" with berger 156 and H1000. The SD and ES are great at 58.4grain (12.5 and 5.4 only 3 shots though) but accuracy is not there (1.29"). I started at 2.995 OAL (max for magazine) and lands are around 3.084 so 89thou jump. I have read the bergers like alot of jump. Next range trip I have a few different OAL to try down to 2.955.

What is your preferred OAL or jump? Any one with similar experience?

Thanks

I'm loading .020" off and I'm getting the same groups.

I don't get groups much smaller than that when I shoot 10-30 round groups of any ammo.

I’m .020 off the lands as well and have had great results never messed with anything deeper. started .020 and had great results

I’m running 156s with N565 and a .30thou jump and never messed with it from there as it shot very well

I should mention, I’m running it in a long action with a 20” barrel

I'm .45thou off but I'm seated at 3.03 in a medium action. I've shot some of the Berger factory rounds through it and I would imagine they are loaded to 2.995.

I looked on the Berger site and from recollection they may have been 2.955 oal…same as Hornady eldx

2.955 is correct

Don't you have more room in a tikka - long mag and bolt stop? I'm just starting reloading my tikka with proof barrel. 3.04 coal which is .025 off for me. Haven't tried anything else yet. Definitely too long for a short action Remington/clone. Accuracy is better than some custom ammo, perhaps because mine is longer, or maybe just a more consistent powder charge. 156 bergers.

The block in the magazine prohibits me from loaded any longer. I think I could get a different caliber tikka magazine for some additional length.

That said, I kinda gave up with the 156 Berger’s…at least for now until I can get some different powders to try. Getting powder in Hawaii is a total PIA. I ended up going nosler ABLR.

I run the 6.5 PRC tikka 24" barrel with the long action mag and bolt stop. My load seated .030 off lands : 156 berger 58.5 grains H1000 ADG brass. Fed 210M primer. velocity is 2915FPS. Very accurate! much more so than N565.
