The 22 creedmoor thread

[KHntr]

88 ELD m’s seem to work at 3000fps impact velocity on bull elk.

Looks like a big bodied animal, well done

Yep. Pretty hefty alright. I’ll weigh the quarters and loose meat in the morning.

My current load is 42.0 with the 88 and is 2975 FPS in an 18" tikka barrel.

What is your 565 load and speed?

45.6gr N565 3355fps 30” barrel. I was running the 88eld at 3175fps in my 22” barrel with N160.

 

[bielenbm]

has anyone tried using N165? I have a pound so I might give it a shot with the 88s

I tried 8208xbr this weekend and experienced pressure. Before I waste any more powder, has anyone developed a load with it?

Seems to be way too fast of a burn rate for this cartridge in my opinion.

I would agree, but I was curious.

Please update this thread if you do try it. Rifles specs & load data also

Had chat gpt run a summary on the go to powder for the 77 tmks mentioned in this thread. Said h4350? But in taking that with a grain of salt. What should I start with?
Still planning on using the 88's but wouldn't mind trying a couple powders with the 77's.

I haven’t loaded any 77’s but it’s great with 75 ELDMs. I’m also curious as to others data for the 77s.

I found heavy charge weights with very high fill rates of N555 and RL23 to give me the best performance from my 22in barrel with 77tmk. They shot well mid 3300s, and mid 3400s. The mid 3400 loads would show pressure in hot weather. If I recall upper 3200s was top end with H4350. The bearing surface on the 77tmk is very long for its weight.

Thanks! I've got 555 and a tab of 23. Wish alliant would go back to the glory days where you can buy their stuff for $25

77 TMK shoots well with RL-26 in my 22 Creed. 88s have shot well with RL-23. Haven’t used H4350 except for when I was testing the 95 SMK.

I settled on superformance with 77 tmks out of a 24" proof barrel. 44 grains got me 3425, I think.

 

[Smokinyotes]

Broke in the new 24” IBI barrel on my Tikka yesterday. Used 42 gr of RS Grand with the 85.5 Berger lrht. Velocity was right around 2900. This was with Hornady brass. I’m going to start load development next week with alpha LRP brass, fed210m, 85.5 Berger’s and RS Grand. Here’s hoping for tiny groups and 3300 fps.

Man I need to try and find this r26 black market. A month ago someone was garage selling some r26. And I didn't buy any

I’m currently shooting 80.5 Berger’s with 40 grains of H4350. Shoots 3300. Next time I’ll probably try N555 as I get better case fill with it. But the H4350 seems to work well.

 

[Nine Banger]

I haven't yet.
After two effed up cases I figure I'd better hold off.

Probably need a bushing die. I've got a 6mm .270 bushing already. Probably be a good winter project. Hoping I figure it out.

I tried one shot and the Hornady case lube that's in a tin.

Maybe I need to trim the brass back to 1.910 before sizing?

My loading skills are definitely good enough to be dangerous but never have tried wildcatting brass down.

That could be it, but I used some short cases and some "regular" cases and it didn't seem to matter except they will get longer.

Try this on the necks after One Shot.

Seems like a good burn rate and is cooler burning than even h1000. Would be a great one to try in this cartridge IMO.
