Reloading for a 6.5 PRC- what’s next

[The_Whitetail_Kid]

Just like the title says- what next. I’ve been playing with the 156 Berger’s for a little while in my 6.5 PRC with a 1:8 twist, and have been getting decent groups, and great speeds, sd’s, and es with H1000 just can’t seem to get the accuracy where I want it. Started long and been working my way back with jump but not getting what I’m after. Thinking about trying LRP’s next rather than magnums. As far as other powders I’ve tried- just H4831 but it was slow. Really feel like the H1000 ought to be the ticket with what I’m seeing on the chrono. Anything else to try? Also, I’m thinking of trying some 150 ABLR’s in the future. Any one have good luck with those?

147ELD?
143 ELDX?
130gr TMK?

N565?

H1000 was slower but more accurate than N565 for me tho.

Forgot to add in im sticking to the 150 class bullets

 

[Kimber7man]

Try N565

I bet the LRP shoot better. And I have better luck seating the 156’s deeper Mine are .060 off the lands. H1000 was more accurate than N565.

Pic is of a 5 shot group.

That’s a hell of a group.

N565 or Retumbo. My Mesa likes N565 with the Berger 156

I shoot Terminal Ascent get 3/4-1" group. I sent my rifle back, Seekins did some tweaking, sent me a paper target back with 0.5-0.75" groups with ELDX. I have not shot them yet. Not sure if I will > prefer bullets with high weight retention.

Hammers would probably shoot very well too.

Retumbo beat out H1000 and H4831sc for speed and accuracy with 156’s. I’d still like to try N565 though…

 

[Firestone]

I've used Retumbo with 156s and gotten good velocitys and have used both magnum and lrp primers with good reults, 156s haven't been very jump sensitive for me either, they kind of have been an easy button

My tikka loves N565 and 147 ELDM with 20 inch barrel suppressed right around 2960fps. Right around .75moa at 100, but when you shoot farther you run it out the smaller it shoots.

 

[WyOwen]

Another one for retumbo and Mag primers.

I have 2 - 6.5 prcs, 18” & 24” barrels. They both like retumbo and a 156 Bergers

When you say accuracy isn't what you're wanting what group sizes are you getting for how many shots?

If you really want to use the 156, I'd try N565. If you aren't set on that bullet, try the 147 ELDM with your H1000.

How many grains of N565 are you loading to get that speed? That's more than 100 fps faster than where I started to see pressure signs with the exact same bullet, powder, and barrel length.

.7-.8. I know I should be getting better than that out of my custom.

For how many shots? If it's 3/4 MOA for 10 shot groups, I'd personally be done with load dev for sure.

3 shot groups is what I usually do. If it was 3/4 for 10 shot groups I’d call it too.

Man what barrel. I have the same setup in tikka and only getting not quite 2785

Sorry it's 2860fps, not 2960 fps. Had to go back and look at my Garmin shot list. Using 57.0 grains of N565.

I was off, it's 2860 fps not 2960. It's an xcaliber barrel.
