Ive ran 77tmk above 3600 with rl26 in a 7.9tw, no blowups.

The 69smk with 39.0gn of Varget from your 22" bll should net you around 3525fps and it does bad things to critters. Its special brother, the 69gn Tipped Matchking is nastier, and an excellent choice for coyotes. The poly tip TMK tends to upset more violently than the SMK. The rib cage pic was after it had come through the near side shoulder as it entered the thoracic cavity. Jacket and core were found under the hide on the off side. This was appx a 110# Oklahoma whitetail that my son shot. Deer went about 30feet, most of which was sideways after he stood back up...his compass didn't really work right after the impact. Lol.

What’s you furthest coyote kill with the 69 smk?
How did it perform at distance?
The tipped match king upsets very well, even at distance. Typically the SMK has a thicker jacket at the meplate and does not upset as violently...but..
I bought a needle finger drill set off of Amazon and used a bit to relieve just a little jacket material on the inside the hollowpoint of the SMK's that my son was running on his deer to expedite meplate upset at impact. It was a bit of an experiment to see what the expansion would be. Violent is an under statement. From this harvest experience, I have decided that for whitetails, I will next try an SMK without the meplate being drilled and see if the expansion is a little slower and if the bullet tends to carry a little more retained weight. While dead is dead, I would prefer not to waste the shoulder if possible and my son is not quite yet practiced enough to start making mostly head shots. I have also decided that for coyotes, I will have him running drilled meplates for the violent expansion. It should be a train wreck on a coyote. The TMK's on coyotes have been excellent out to around 400yds, I have not yet hit a coyote at distance with a drilled SMK. In a 556, an undrilled 69smk is best off when put on the shoulder blade to aid in upset at the lower speeds. I don't think that will be necessary at creed speed. Still a work in progress, but for the price of $15 off Amazon, the needle drill seems to have helped keep the typically tougher SMK from penciling through, and added another option to keep the guns running during our unprecedented components shortage. My first choice is the 69 Tipped Match King, but so far, with the drilled meplate, I am happy with the information that I have gathered on the good ole SMK.

Saw your post on fb. Lol. Wonder what the velocity jump to rl26 would be? It's a longer barrel then I ordered, but I am a short barrel snob, ill sacrifice velocity, although with rl26 I might not be.
Whats the chamber option? I didnt see 22creed on their drop downs but I was looking at it a few days ago again hoping to see it
Who makes Tikka prefits in 22 Creedmoor? Or is it easier to buy a stainless 22-250 with 1-8” twist and rechamber?

Xcaliber does as well. Or rechamber a 22-250 like you are asking, I'm about to do it.
I've seen some killer data coming from them. Velocity and accuracy, but it is the internet. I wouldn't hesitate to try them.
Looks good, and plenty of room to move up. My 22" runs 3393fps with 42.2gn of h4350 pushing the Berger 80.5's in lapua sRP brass. I could easily lean on it some more to get over 3400fps, but this load is easy on brass and does everything I need it to, and a few more fps wouldn't gain anything worth the cost.

Will work just fine for 65/69 up to 85/88's. Too fast for light weights and a smidge slow for the 95's. Just depends upon your plans for the rifle.
7 twist is pretty fast if someone is pushing the lighter weight bullets at a decent speed.
Im still trying to figure that out myself but I know he asked for 1:8, so I just wanted to point it out.
More than likely ill stay in the 75-ELM/77TMK and MAYBE stretch it out to 88ELD-M but im not sure id go that high in weight or not.
They do. However, I feel like its super easy to always say its the shooter. They will re-inspect the barrel but you have to send them your entire gun including scope etc, exactly how you had it set up. Sounds like they will test the entire system but that shipping costs would get up there quickly.
I see your point on altitude… that same combo at SL gets me “marginal” stability.Usually when I'm trying to figure out what twist I need, I consult two things. Bergers stability calculator and the RPM formula. Got to make sure it's stable but doesn't spin faster than 300K. Altitude, temp, and bullet length counts for a lot in stability while it matters not in RPM. Bullet caliber, weight, and length also matter not. It's all twist rate and speed.
I'm shooting a C6 1:7.7" in 22 Creedmoor. At 6000ft ASL.

Twist Rate Stability Calculator
Our newly updated Twist Rate Stability Calculator not only tells you what your SG is, but it also lets you know if you are reaching your optimized BC.bergerbullets.com
RPMs
MV(12/twist rate)60= RPMs
3150 x (12÷7.7) x 60 = 294,525rpms.
For RPM formula…12 and 60 don’t need to be separated.
MV ÷ twist x 720 = RPM
I’m only at 800 ASL, that compared to 6000ASL as someone posted above is a massive difference. Not sure I’ve ever run those numbers that way before to notice
I picked up a used 6.5CM Bergara B14 Ridge and had my gunsmith rebarrel to 22CM. Staying with the stats originally requested on this post::
Berger / 85.5 gr / Long Range Hybrid Target
H4350
39.2gr
CCI 450 magnum SRP
3137 avg Velocity (3142, 3136, 3134): SD=4, ES=8
Benchmark SS #5 / 1:8 / 22" / fluted / threaded / coated
69 rounds from 9/4/22 - 1/1/23
6mm Lapua brass necked down to .263, then .253 with Redding bushing dies
Advanced Armament CO 762-sdn-6 suppressor
VLD is wrong in the picture

Shouldn't be a problem for the barrel. I'm shooting an osprey with a loaded neck diameter of .255 using 90 grain SMK's
Brand new Wilson 1:8 twist 22"
39 grains of Varget and 69 TMK's did 3,530 FPS with Alpha SRP brass. No pressure signs yet but sometimes those show up more after a few loading cycles on the brass. Going to try this on a coyote or 2.
40.0 grains of H4350 gave me 3,250 fps with an 80 ELD-M. I didn't load any higher charges but I imagine I could push this to 42.0 grains and ~3,400 FPS.

I'll chrono the load and post it when I can. This was finalizing load development. I didn't want to chase velocity, just accuracy.
i built a new 22 cred and am doing well with my main 77 Gr sierra tmk load and 39 gr of H4350, but am wanting to build one for a 65 grain sierra gameking SBT.…
Does anyone have any ideas on a starting load? I have h4350, superformance and several other powder Options. Thanks

Your 39gr H4350 load is pretty light. I'd start at 40 with the 65 maybe even 41gr.
If you have Varget, start at 38.5gn and work up with the 65gn SGK. Shooters World Match should be in that neighborhood as well.
Not following the format but for the post but I am looking for some advice.
I have everything to assemble my 22 Creed but haven’t had my blank chambered. Any recommendations for a gunsmith? 6.5 twist bartlein, I plan to shoot 70-90gr bullets in a shorter barrel length (18”-20”) any advice would be much appreciated. I know I may have to use solids with that fast twist but thought I’d give it a go.

Perhaps you should understand simple things like that before trying your hand at reloading! https://www.snipershide.com/shooting/threads/the-chode-american-precision-arms.7159477/

How about you all take your petty bullshit somewhere else?
I'll try to get this back on track...
I have 75 ELDMs and a 20 inch barrel coming. Alpha brass.
I have RL26, H1000, H4350, Varget, and Superformance as candidates.
I'd like to use RL26 or H1000, but am thinking I may need a heavier bullet and / or longer barrel to maximize their potential.
Thoughts? Should I just skip right to H4350 since I know that will work?

I would break the barrel in with H4350 since it is a known performer then dabble with the other powders after getting some 85.5 bergers to try.
