Primer showdown: WOLF vs. CCI #41

[markm]

I'm willing to try your 77 load next weekend. But I'm going to run this 69 gr test load first.

Explain more. Carbon ring where?

In the throat. If you have excess carbon build up it can increase pressures a lot. Have you tried to scrub the entire barrel down to raw steel to create a baseline?

Had some good luck with the 69gr RMR, 23.0 TAC and the Evil primers. Some light swiping on maybe 1 out of 10 cases. We shot a bunch through a suppressed LMT 10.5 to really pressurize the cases too.

2762 fps with an SD of 36 from the 20" bolt gun. I have 9 other 69 gr chrono numbers from the same gun that average 2859 fps. This load is the slowest load for 69gr I've done and still shows some light swiping.

These primers are shit. But at least I can make Chrome lined blaster ammo.

The load held MOA popped steel
Nicely from CQB to off hand out to 150 with ease. I thought it shot very nicely.

But the real excitement for the day was the 88gr ELD’s out of the Tikka. We made headshots at 750 and went 3/5 at 1,300. That load rocked.

My typical blasting load for the last few years has been CCI #41/ 25.5gr TAC /55gr FMJ. We're at subzero Temps around here, but I'm hoping I don't end up with nasty surprises from my most recent batch. I'll have to find a way to test them despite the extreme temperatures.

Headshots at 750 is insane!

Yea our 750 target has a center flapper that helps you walk it in, but it’s still a challenge. It’s very cool the flapper disappears and the target doesn’t budge. Most rewarding. I spanked it a bit too hard twice with the 300 yesterday that will now require a maintenance visit next week. But worth it.

Stepped out and shot 10 rounds of the #41/25.5grTAC/55grFMJ load today from a 6920 barrel. Only 3 degrees out, but I set the mag on top of the dash vents and blasted it until it was time to shoot. Not so scientific, but the best I can do on the frozen tundra until spring. Primers stayed round, hopefully this remains a good load once spring gets here. Primers are from within the last 18 months.

Edited to add this is brass towards the end of it's life. It's been reloaded multiple times, but I'm not seeing anything showing high pressures. I'll try to chrono the load next time.

Those look great. I'm planning to use my mixed brass with the CCIs and TAC for a ball powder blaster load. I found one piece of brass Saturday where the primer had partially backed out, but it could have been missed from a previous week's shoot.

Dude this is my fav load too! Nosler 77gr with LC brass, CCI41s and 23.7gr Tac (23.8 works the same for this node).

I really hope CCI in recent batches hasn't shit the bed on QC or their traditional formula. I also use the CCI 41s with Alpha SRP brass in the 6.5CM so I can get decent cold weather ignition.

Hmm i was using 24.2gr tac, maybe I can get better results with the lighter load.

Im using 24.8gr, not getting swipes, and 2725-ish from a 16", but 12-17sd
