Does it shoot good?
Checking the bore would be the next step I would take. If no carbon build up in throat and first few inches of barrel then inspection of bore for diameter is needed.

Sounds like size die is not sizing brass enough? If case cannot expand at all this will make pressure higher ... expanding case act like a shock absorber ...same as water on rnd or in chamber causes an over pressure condition on upper end loads.

Hammers with 4166 at 2975 and RL 16 (slow, but I haven’t done much load dev).

The sizing die works fine for the 4166 and Rl16 cases.


The barrel shoots great with other powders no complaints, I just wanted to find a way to make varget work because I have a lot of it. After hearing the loads/velocity everyone is getting here, it’s making me scratch my head. Maybe I have a hot lot of Varget.

No donut (bullet is not seated bast neck shoulder junction).

I will check for carbon ring tonight, but it has done this since new.
Adding an extra 0.001" to the freebore diameter (Not lenght) also help getting rid of any potential carbon ring issues.

    Been a while since I did any shooting with my 22BR, had a baby girl 12/27, wife was in hospital 2x with post pregnancy serious infection. Sleepless nights and slammed busy with work. Thank god thats behind us! haha. Shes 7 months now, everyone is good and getting more sleep these days. Finally a little time to play with some of these projects.

    So my custom 22BR reamer came from Manson a few months ago, been sitting in the shop. I have a Bartlein 1:7.5 HV .218 blank that PVA will be chambering this week with my new reamer. Tightened up the neck a little, 0.254 and 0.130 freebore. Also have a 22GT Osprey that Ill compare to the 22BR. So how much faster it is with same bullets and barrel life

    Originally wanted to go GT but I might just do a BR. Problem is I’m loaded down with H4350. Seems like people are having alright results with it. Anyone having recent luck with 88s and H4350?

    Never been a BR/BRA/BRX or GT guy, just a 6.5G and 6.5x47L, but the squat little cases with a .224 bullet sitting on top is starting to intrigue me.

    Please excuse the JV question, but what would the velocity look like when comparing say the 22 Grendel, 22 GT, 22 BR, and 22x47L?

    I know I wouldn't go with something as large as 22 Creed due to the barrel life, but what about the little guys from the Grendel on up? Does the 22x47L also get into barrel burner territory based on the case volume?

    Thanks

    I can't speak for all of those but for the 22 Grendel you're looking at 2800 - 2850 with 88's out of a 22" AR barrel. The 22 BR is doing about 2950 - 3000 out of the same barrel length. I'm betting the 22x47 is in between 22-250 and 22-250AI/ 6 Creed speeds.

    26" 22gt, with 90s and H4350 I never found pressure working up to 3270fps, close tho, alpha brass was just starting to show the ejector slot from the bighorn bolt. I run it at 3100. Good accuracy at 3200 as well, but why burn the throat. I'd think the 22x47 would likely top out 3320-3350. 22creed, mine will push 88s just under 3400......from a 22" barrel. Due to the overbore, i bet a 26" would make near 3500, but jackets may fail. All my fast twist 224 barrels are 219 bore diameter, 8 twist I dont think it matters as much unless you're trying to push lighter bullets at mach speed. If I were to persue a br based variant, I'd go 22 bra with alpha brass. You lose very little to the dasher, but gain fair bit over br. Cases dont grow, they hold pressure very well, long neck is generous for various bullet lengths. I really like my 6bra, stupid accurate rifle.

    Just loaded a dummy round for my smith....Lapua 6BR brass resized with a cheap Redding full length sizing die, expanded with a .223 mandrel and seated a Berger 85.5 LRHT to 2.330" COAL. Can't wait to start load development for this little cartridge!

    Man that's so sweet. Good shooting! Makes me want to put a 22bra reamer together. Get away with a lil slower burn rate, run a tad bit more velocity. Plus I already have the dies for 6bra.

    Since the dasher is in the br family, would this thread be helpful in load dev for a 22 dasher?

    One thing that cost me a few pieces of brass was insufficient outside chamfer. Once I put a good chamfer on, I did all my necking down in one step. Used a honed Forster die, went straight to my target neck OD (0.004" under loaded).

    Worked up 88 eld's with varget and reloder 16 in a 21" Shilen 1-7".

    Varget didn't seem to wanna shoot good anywhwere near like 16 but velocity was a little better.

    2,950 with a case load of 16.

    Need to chrony and check es/sd
    Have you ever tried n150?

    Anyone have a JGS 255nk 130 freebore(225 diameter) they'd be willing lend to Manzella Precision to chamber my new barrel? I'll pay a wear/tear fee and all shipping.

    @padom are you neck turning on the new 254 nk chamber? Seems like most are using 255nk.

    Curious what loaded neck diameter you guys are getting with necked down unturned lapua? I figured it'd be around 0.250", speccing out a reamer for order right now.

    I don't have br dies, so I'm looking at Wilson or Harrels FL bushing dies. Might as well go with the a 6br die, as it's multi use over the 22br available from Wilson.

    Nope and have plenty of clearance. I tightened my neck up a hair because of my fired vs loaded neck diameter difference. Leaves me .002 per side

    I just checked my print...my new reamer has a .255 neck not .254! My mistake...the PVA had a .256 neck...I tightened it up .001

    I've found amp 6br aztec anneal code to be 152-155 depending on load psi, anyone use the aztec for 22br? Is it near 165/170 to heat the small necks up? Lapua 22cm turned is 175 aztec in my testing.

    I am getting an AZTEC code of 0155 for my 6BRA and 0158 for the 22BR.

    I anneal every firing and both shooting very well.

    Finally got some time to get some rounds down range, started with seating depth while the barrel speeds up. Starting load of 27.0 grains of Varget with the Berger 85.5 hybrid seated with .005 jump gave me 2,832 fps. Group shown below are shots 9-11 out of the Benchmark 1:7.5 twist in MTU contour finished at 26" and for those that believe shooting suppressed compromises accuracy........

    So, I loaded up from 27.6 to 30.4 of varget and an 88gr ELDM and got pressure to the point of popping primers at 30.1.

    Any clue.

    Anyone running lighter bullets? Shorter freebore? Just curious. Pondering a low recoil hunting round, 77tmk have an excellent reputation for killing deer even elk with proper placement. Would likely be a 20" pipe for supressor use.

    I'm unning the 75eldm from an 18" 22cm. Loads sub moa at 400y with no powder tune, just some seating depth tweaks. Running 3100fps. Shot two mulies yesterday morning. First was large body buck at 275y(2600fps impact), in the crease, did a 50y death sprint and piled up, massive lung trauma, deer bleed out profusely from the mouth before I got to him, no blood as I cut neck, it was all in the boiler room and on ground. Nickel entrance through a rib, exit was quarter size throug a rib. Next was a younger medium body buck, 475y(2250fps impact), strong crosswind, but my nephew who's never killed a deer, put the bullet at the neck shoulder junction, pencil entrance, quarter exit. That deer was lights out. I was impressed with bullet performance. This load is no pressure, and is only 40gr H4350 I feel another 150fps is on the table. I also only have 65 rounds down the pipe but has already speed up 50-60 from first 20 rounds.

    What twist is the barrel?
    7tw osprey 219 bore at 18" I will likely run 88s for hunting at around 3000fps or so. Faster velocity makes em prone to over expansion for splashy results on game. My 22br reamer is ordered will be 0.140 freebore for heavies like the 90atip. My 22cm is freebore at 0.120 and works with 75s seated 37k off lands. They're well above neck shoulder junction. As throat wears away I'll likely switch to 77tmk as the bearing surface is quite a bit longer.

    Edit for grammar.
