Ok thanks75 eldm 10thou off with 42.6gr h4350 is 3420fps in my 22". Only needs half a dime to cover groups.
Work up to that. It shows no pressure in Peterson srp brass, I worked up to that after barrel sped up 80fps.Ok thanks
41.4 gr of RL16 gives me 3330 FPS out of a 20" barrel. Alpha brass. Shoots great.Has anyone had any luck with the Hornaday 75 edlm s In their 22 CM I have some Berger 80.5 but Hornaday is cheaper?
That’s good to know! Mine is a 8 twist 22” barrel with the 75 Gr Hornadys @ 3440 FPSFor those looking at which twist rate they want IMO I would avoid 6.5 twist. IMO I think 7 is too fast as well. My next 22CM barrel will be an 8 twist. I shot 88 grain ELDM's and I was stuck at 3200 FPS and the reason was RPM's. When deciding on a bullet and if you have an idea on velocity then I would calculate RPM's and make sure you are okay with rpm's and velocity. I was blowing up rounds in a new barrel because of RPM's. Good luck. Also a quick phone call to the bullet maker to find out what RPM the bullet can handle can save you some regret.
All of this is my experience. Your experience may vary. Good luck

7 tw for some 90gr bergers, they seem to be the only heavy bullet thar won't eat itself at more than 3100fps. 24" 7tw slings 90s@3230, my 22" 8tw sends 75gr@3430.
I've shot prob 400 hundred 85.5s through my 7tw osprey blank, no issues. Ran 75s at 3250 without problem either. Velocity is lower tho as it's an 18" barrel.7 tw for some 90gr bergers, they seem to be the only heavy bullet thar won't eat itself at more than 3100fps. 24" 7tw slings 90s@3230, my 22" 8tw sends 75gr@3430.
So far 95’s have worked well at 3080fps in a 7 twist Mullerworks for me.I have shot about 200 90 grain sierra's at 3100+ fps without issue in a 26" 7 twist Osprey. I will soon start working with 95 grain Sierra's and hope for the same results. The only bullets I have had come apart were 147 ELDM's in my 6.5 PRC.
Sounds good I’m running a 8 twist so I will be running between 75 & 80 grain bulletsSo far 95’s have worked well at 3080fps in a 7 twist Mullerworks for me.
The 95smk is fine at 3000 max. I had issues with them randomly in a new 7tw barrel. Thinking since it happened at several different velocities(3020, 3110, and 3180) sporadically, it must be a bullet lot issue. Sierra ballistician I talked with flat out said those were designed for 223 and 224valk, at their speeds. In a bigger 22 case they would desinigrate.. I mention I'd saw several guys post about it working, to this he laughed and said "for now, let them get a little throat wear and see how they like it." If it works fine, but it isn't gonna work long enough to wear out a barrel. I can see it being good for a short barrel that will not be over 3000fps, but handicapping a 26" pipe to 3000fps with a 95smk or rolling a 90gr berger at 3230 is a no brainer for me.I have shot about 200 90 grain sierra's at 3100+ fps without issue in a 26" 7 twist Osprey.

I wish you luck, maybe with fresh barrel and 5r type rifling, they will hang together for a little bit. I found the 90hr berger to be more accurate and easier to load. The bc difference, at same speed, wasn't worth the hassle and blow ups. Factor in throttling back the 95smk and the bc wasn't worth it.So far 95’s have worked well at 3080fps in a 7 twist Mullerworks for me.
Barrel is now in the corner and replaced with a 6.5x47 barrel. I may dabble with the 22 Creedmoor down the road if I want a bolt action coyote rifle instead of my AR-10 .243.I wish you luck, maybe with fresh barrel and 5r type rifling, they will hang together for a little bit.

Thanks for the info. I believe the Sierra representative. I also believe, as stated before on this site that the bore size has a lot to do with it. The osprey is .219 as opposed to say a Kreiger which is .218. I have 15 rounds loaded up to test in my rifle that currently has 462 rounds through it.

All I'm saying is that the 95smk, according to Sierra, was designed around 223 and 224valk speeds. That's 2500-2900(maybe optimistic), you start hammering on them in a creedmoor at 3000+ and it's a crapshoot on whether they stay together. And if they work today, there's no guarantee they'll work in 400+ rds of barrel wear. My point was the 90gr berger hangs together up to 3300 in a 7tw 22 creed, shot better at 3230 so I settled there. In over 100+rds, I've yet to have any weird impacts, just where they expected to go. The 95smk, I had 3 or 4 out of 24 not get to the target or land sideways(jacket presumably starting to fail and causing yawing). That happened at low speeds of 3050 and a higher. No amount of hoping will make that work.Have you done the analysis to see where differing twists, RPMs, speed, BC, and stability intersect? Like how much is the BC degraded? And does it make a difference in wind error forgiveness at distance? Or does it matter so much that a person can shoot a lighter/ shorter bullet with a poorer BC faster to make up the difference? Just curious; not a loaded question.
As far as twist rate and rpms go it's completely agnostic of bullet weight or length, barrel length, or altitude. It pretty much establishes a glass ceiling of top speed. But stability can be managed by twist rate, speed, and altitude at the cost of BC. I guess the question is: At each individual persons altitude, what is the BC cost of keeping the 95 SMK below 300K RPMs? Whether by speed or reduced twist? Is that BC cost negligible in wind drift at distance or is it considerable? And then finally, if you self-limit to another sturdier bullet, are you still limited by speed and does that bullet have an optimized BC that is better than the 95's degraded BC?
My dope was true to 1260yds using .308 BC at 3080fps.I guess if nothing else shoots good in the heavy weights except 95smk in a given barrel, it would be viable in sub 2950 range. Do you know what the g7 is of the 95smk? All I'm seeing is the banded bc
Just shot 41 grains of h4350 no signs of pressure wonder if I could just jump to 42 grains or just go up a half of a grain using 6 cm lapua brass 450 primers 75 edlm bullets.I know several folks including myself have been playing with the 22 creedmoor for a while now. Please keep this thread to actual reloading information, and if you can please post some round count, barrel life numbers are all over the place.
Here is a brief summary of the cartridge. You need to know that it is a laser beam and varmint vaporizer! The 22 creed feeds awesome out of a aics/aw mags, has increased case capacity, and can toss 80gr pills over 3400fps. Also, you can use youre existing creedmoor die sets with a different bushing and seater or call up whidden and get a custom set. Using 6mm creedmoor brass is the easiest way to make brass, but some have fireformed 22-250 brass into 22creed.

I was breaking in my 22CM with lapua brass 41 grains of H4350 1/8 twist 75 grain edlm bullets don’t know the freebore forgot to ask gunsmith just told him to set it up with that bullet just wondering if I could jump to 42 gains or no . 41 grains showed no pressure signs .For brass you might look into Alpha Brass. I believe they will be doing a full production run of 22 Creedmoor in the next 45-60 days if not sooner.

Ok thanksToo funny,
Seems like most land right around 42gr of H4350. I'm planning to start at 41, work up to 42gr with a 75 ELD as soon as Fritz is done with the barrel.
what load & powder does anyone use for the berger 85.5 ?For what this is worth, my load above shoots great with Hornady brass but as with most tinkers I wanted to try some loads using small rifle primers. I bought some Peterson 6 Creed brass ( seems to be very good brass) and have been trying to use RL26 with CCI 400 AND 450 primers and it's been very unfulfilling with wild velocity swings. I will try again later using faster burning powders but for now back to the proven.
I use 4831sc or N560 with 90gr bergerswhat load & powder does anyone use for the berger 85.5 ?

Some barrel questions…
1. Shooting 80-90s, what’s the verdict on twist? 7? 8? Somewhere in between?
2. Min barrel length? I’m thinking 22 with a TB Ultra 7 attached all the time. Anyone going 20 or shorter?
Throat erosion.. I tied them when the barrel was new and I couldn’t get them to shoot good. I tried the Bergers then and it loved them. Fast forward 600rds and a little over .125” of throat erosion, I couldn’t chase the lands anymore and lost some accuracy so I revisited the 88s and they have a lot more bearing surface. I seat them .005 off the lands and get 3200fps with .25 moa or better. Now, the 88s perform the same or better than the 85.5s, performance numbers, BC etc. are the same or better and the price is less than half… that’s very hard to ignore for sure! So I switched to those and am shooting more for less with the same or better accuracy numbers.Why did you switch bullets?
I've been shooting the 85.5's in a 22GT and I've been super impressed with them. They are up there with the venable 105 Hybrids imo.
What kind of barrel life are you seeing with the 22cm? Any worse than a 22-250?I’m running a 26” barrel in 1:7 RH Twist… I had a custom reamer made by JGS for my first rebarrel. I figured it would be best to get ahead of things for when the time is right. The reamer arrived and I got the itch to have a barrel cut to have ready to go.
FYI.. current barrel has just over 600rds through it. It’s a REM Heavy Varmint Barrel 26” 7 Twist. The replacement barrel is 26” M24 7 Twist.
As far as bullets go, I used to shoot Berger 85.5gr LRHTs and then switched to 88gr ELD-Ms. They both shoot light out.
I haven’t burned through my first yet but made another barrel just in case. I don’t know the barrel life yet but have been documenting for when it’s done. From everything I hear, they’re around 1200-1800 depending on how you treat them of course. I don’t worry about it though, it’s like a sports car, you don’t look at the price of gas or the mileage, you just drive and enjoy the experience.What kind of barrel life are you seeing with the 22cm?

I'm running an 18" 7.5tw 219 bore ace lt palma, always suppressed. More of a utilitarian hunting/target build at 10-11# all up. Shooting 88s and 90s, running 3100fps with H4350 or N555. I've had 3 22cm barrels now, 22in 8tw was the first, 2nd was 18in 7tw, this ones 18in 7.5tw.Collecting parts for a new build I plan to shoot suppressed 100% of the time.
