22 creedmoor

#951
Guys , I just got on here after a long hiatus, I have got to say, I am impressed with some of the test results you guys have been getting with this cartridge, I burned up one barrel shortly after starting this thread and I've got a spare barrel in the safe, it has always been one of my favorites, you comp guys running these new 90+ bullets are doing what I always thought was a bad ass match round.

I applaud you guys for smoking rounds down down range.
I'm back in the game again but for hunting only and I've got some 50 gr sierras im about to test out on some Yotes, Remember.....Speed Kills!

good luck to anyone who jumps into this fun round, take care

How many rounds did you put through the barrel before it was shot out?

Anyone have the 90 grain ALCOs start to come apart at 3060ish fps?

With a 26” barrel I was able to get them to 3150ish. But I can’t get a decent ES or group size. I think it’s because when the bolt goes forward the inertia moves them about .010. I have a crimp die so maybe that will help?

I’ll get ahold of some of that VV555. Do you have a starting charge weight?

I also blew up 2 ALCO 90 grain bullets at 3070fps. 3030 fps didn’t have any problems and produced a 3/4” group.

What primers do you use?

Impact velocity was about 1600 or so then?

From the pictures it seems that the bullet was able to achieve fragmentation it would seem. Is that correct?

Nicely done.

With H1000 and 95smk I’m guessing I should find a load somewhere between 42gr-44gr? Of all the information I’ve searched through this is kind of what I have seen. Just wanted to make sure I was on the right path.

With H-1000 I started at 41.5 and went to 45.2, best node was at 3050s with 44.2 grains.

I tired, H4350, 4831SC, RL26, N565, and H-1000
Current load is 43.00 of N565 for 3010

I have 5 to 600 through mine I would guesstimate maybe towards 700 I haven’t kept track like I should . Running 75’s at 3435 with 41h4350. Throat is really fire cracked. But it still shoots in the .3s

I tried that combo and it was terrible. TS Custom barrel, 1:7, 22". Then someone commented on this thread that was way too slow of a powder for that bullet. Settled on RL26 and 88 eldm which was amazing.

What speeds can I expect out of a 16.5 shooting 50-60gr pills? I am considering going to a smaller more efficient case like a 22GT over the creedmoor, unless I can still get blistering speeds with a short barrel. I already own the barrel so I am set on the length. Any input?

What you’re talking about is my setup. I have two loads for my 16” 22creed. Mine is a 1-8t X-Caliber.

60g Berger FBV @3430
68g Hammer HHT’s @3450 (leaning on it)

If anyone is looking for 22 CM brass, Grafs has 100pcs of Peterson for $79. Comes in a bag, with a label that reads "Major Manufacturer blah blah blah" Don't know if the brass is "seconds" or blem but they look exactly like the 50 I bout for $56.

If this post doesn't belong here, please let me know.

I thought I'd try a 22creed, seems like a neat rd. Nuke 2.0 action, 26" varm criterion 7tw barrel nut, Peterson srp 22creed brass, cci450, h4831sc and 95smk. Started load testing today with 42.4gr set as max, with plans to go up if primers looked alright. Bullets are set .020 off rifling as a generic starting point. Anywho, 5 powder weights/3rds per weight just to see what it will do. Ground was saturated and bright sun/60° with 4-5mph wind= some mirage and soup to deal with.

Everything was going fine until first rd of the 4th powder charge. Bullet didn't impact as predicted. As I scanned target in that area, I then saw a large rip 4" low and 3-4"left of aiming point. I shot the next 2 rds and they landed as predicted. Shot the 5th charge weight and those rds performed as expected.

Has anyone saw or heard issues with 95smk? I generally assume keyholes are too slow fps/too slow twist. I had no issue at slower/lower powder charges. Barrel was allowed to cool to ambient before string. Got any ideas?

I'd read through the 20pages of 22creed loads and seemed that guys that had 6.5tw barrels seemed to have issues with bullet blow ups and as barrel wore seemed more frequent. It just seemed weird that I had a keyhole at that speed. I'd have thought at lower charges, ok, but those holes are perfectly rd.
 
#989
30rds on barrel, only had 42.4 loaded as max, didn't want to trash brass or pull down if I hit pressure. That was 42.0 and ave 3060fps. The start load was 2990. All bullet holes were rd, except the first shot of 42.0gr(3065fps). It about had to be a bullet issue. Everything was stable above and below it.
 
#991
Yep, I've saw guys drive them a fair amount faster. The bullet blowups I've saw, no part of the bullet got past 35yds, much less to 100yds. Keyholes on target were stability issue or baffle strikes, I thought. I would think if I'm on edge of stability at 3060 or 3140, than the slower loads would have failed miserably. And if I was blowing up a bullet at 3062fps, then every bullet shot today(3110ave, 3142ave, and 3172 ave) would have blew up. Just checked actual twist in barrel with a tight patch, right at 7tw or maybe a smidge faster.
 
#993
Running the numbers in berger stability Calc, not sure how a 95smk can be run without blow up or stability issue. My load is 1.35 and 1.34. To get to magical 1.5, it needs 3225fps and a 6.5tw which is spinning bullets at 358k rpm. It's does shoot the 85.5bergers really well, only downside is this chamber is perfect for 95smk. With the bergers, to get within .060 of rifling, the bearing surface area is only in case nk about .130". I don't like having less than bullet dia of bearing surface in nk, but to get close to that I'd be jumping .140". For some reason, the berger loads will show first rd being 40+fps faster than the rest of the string. Any other load or rifle doesn't do that, so has to be something about this load. 1 example, but every 85.5 load does this.

@6brshooter I think the 95 SMK is just not for you. I would pick a shorter / lighter bullet. And I wouldn't worry so much about getting close to the lands. I'm jumping the 75 ELDM a mile and it hammers.

Yeah, that's where I'm at. I did just talk to Sierra tech, he was pretty familiar with that 95smk and it was designed for service rifle and needed 6.5 tw to stabilize it but it wouldn't take the rpm that the bigger 22s would launch at. I did tell him that some guys were getting them to work and his reply was wait until their barrel has 4-600rds on it and see how they like it. I asked about the 90gr smk and he said it was the same as 95, just not designed for the bigger 22s speed. Super nice guy and seemed fairly knowledgeable but not sure what the point Sierra is trying to do. Make the big heavy for caliber bullets for cartridges with balls, not 223 or 224valk. He recommended the 80smk for its toughness, but its pretty lame bc wise. I will soldier on with the 85.5 as they haven't landed sideways and have shot the better groups so far in testing.

I saw 85.5’s blow up last year in a match and the guy was using 22GT at the 3200fps speed limit for PRS.

Yeah. I was all set to get some 90smk to try but I can't find any less than 250 quantities and don't want that many if they don't shoot or land sideways. I wish this freebore was .060 shorter and it was a 7.5 or 8. I knew that there would be a narrow envelope between stability-accuracy-blow up, but its almost so narrow that the wiggle room in nonexistent. When these super long bullets get going this fast and some wear/firecracking of barrel is in play, the fps and tw really start fighting each other.

I did just talk to forster, my 22creed fl sizer die is overhoned in nk and doesn't add any nk tension. .250 pin gage jiggles in nk of die and expander is .2225(at least it's correct). My 1x fired sized brass is a slip fit on bullets, fml.
