[357Max]

6.5 PRC only

@Rob01 - Can we do a sticky for 6.5 PRC?

Just starting a load work up. I need your favorite accuracy loads.

Please provide:

long or short action

Bullet weight and Mfg.
Powder and charge in grains
Cartridge OAL, yes OAL. If you want to include ogive list the comparator used.
Primer
Brass Mfg.
Velocity
Barrel length
Freebore of your chamber if known

Comments on function, brass life, accuracy, temp stability.

Today I ran 50 fire forming loads for new ADG brass. The idea was to use up bullets and powder I don't like while fire forming.

Short action Mausingfield M7
Win. Staball 6.5
54.5 gr x 35
Norma Golden Target 130gr Advertised G1 .610 (I plugged in .585 to Strelok Pro) hit centered at 500.
Seated for max mag length 2.960 This shot the best @ .875" for 5 avg speed 3090
Seated 5 @ 2.947
Seated 5 @ 2.935
avg speed 3090
checked several five round groups for velocity out of the car rounds were cool 1st group avg 3090 SD 9.5, then 3115 SD 22, then 3085 SD16.2. Temp stability seems pretty good.
New ADG brass. Chamfer od/id & mandrel with .2625
CCI #34
26" Helix 6/ 8T Braked
9lb gun

3 x 5 round ladders with Berger 144 LRHT seated for max mag 2.960
Vit N565
57.4 = 2942 SD 11.2 1.1"
57.9 = 2972 SD 13.9 .875"

I'll be loading the 156 eol in this fire formed brass with N565 next.

Bergara Premier Pro short action 26” 1:8”
Bullet: Berger 140gr Hybrid Target (#26714)
Brass: Lapua
Primer: RWS LR magnum
Powder and charge: VV N570 61.0gr (Pretty stable through 55 to 75 degrees temperature.)
Seating: CBTO 2.342” (.005” jump) (Sorry, I don’t measure OAL because I single feed.)

This is a finicky rifle, I’ll admit. I’ll be bedding it and see if I can wring out some tighter groups. This load is 1.5gr below Berger’s max load with the N570, and it is not a compressed load. I have no signs of excessive pressure. Primers look great, no ejector marks, and very little case expansion. I am bumping the shoulder only .0005”, which gives a slight resistance when chambering a case. Neck tension is .003” (bushing die). I anneal every firing, so case life should be long. BTW, I only started development with fire formed cases, and I tried three different seating depths before deciding on the .005” jump.

Here’s the numbers from the Garmin.

I’m happy with this load. I’m not as happy with the rifle. After bedding, I hope to eliminate some anomalies and tighten the groups. Best accuracy I’ve achieved is .386” at 102 yards (5 shots). I know that this is a factory offering, but I would like to see how far I can go.

It took way too many rounds fired to achieve this. I fire formed a hundred cases, then started with OCW tests (16 different weights), and then three different seating depths. My total rounds to get this load was 250. Yes…it took a while.

Tikka Action with 24” proof CF prefit 1:7.5”, suppressed
Bullet: Hornady 143 ELDx
Brass: Peterson
Primer: Federal 210
Powder and charge: H1000 58.7gr
Seating: 2.95 OAL, can't recall CBTO off the top of my head

2975 FPS avg and shoots in the .3's.

May tinker with the 147 ELDM before deer season, but this is strictly my big game hunting rifle so don't shoot it much
