CZ Firearms is helping the Canadian Liberal Party confiscate firearms from legal owners

I'm not sure they actually have a plan for how they're going to confiscate privately owned guns yet. The only ones they've taken so far were ones that gun dealers had in stock. I can't really see too many retailers being willing to help the government on this one either.

I've lived in a few provinces, and a number of towns/cities in each. I've had interactions with a fair number of officers, both 'local police' as well as district RCMP. I can honestly say, there are quite a number of good individuals in Western Canada.

Unfortunately, I can also say that there are more than a few whom aren't. I'm sure that's the story where you are, too.

Henderson neck turning

45-90 is right about the triway cutters sucking if you have to remove .100 + like you do for these Sig 277 - 6.5C conversions.
Problem is not everyone has a precision lathe with 220 3 phase etc.
I tried turning some of these Sig cases on my mini lathe and it was painfully slow.

This cutter rocks now that I fixed the chip clearing. Also found an easier way to set cutter depth by just putting a .015 feeler gauge between cutter and mandrel. Cut necks to .014" on the money.

That little Lyman rips bulk cuts off when you need to remove a lot so it'll stay on my bench. I just trimmed to within about .005 on the Lyman.

Reshaped the neck turn tool so it wouldn't clog up with chips every 3 cases.

After fixing the cutter head I tried my first run of 120 cases.

Trimming .005 with the tri-way took 20:05 minutes measuring 1 in about every 10 or so.

Neck turning took 23:12 minutes. I don't really have a frame of reference if this is good? Beats the living snot out of my mini lathe.
I'm not really a fan of turning necks but these 277 Fury cases are great in a large frame AR 6.5C & they kind of need it.

Snipers Hide loads using these cases.

I wasn't trying to load this hot dammit. Intent is to just run near max pressure bolt gun loads in the AR without tearing up cases.
Let's just chalk this up to science. Will not run at this level, but Damn.

It's nice using cases that have pressure head room. For whatever reason all 3 of these beat the hell out of predicted velocity using 3 different powders. All loads were in 3 x fired converted Sig Fury cases.

18" AR with +2" RL gas 7.5 twist suppressed. All ejected at 3:00 - 4:00 o'clock without any gas adjustments between loads.

144 Berger LRHT seated 2.850" using Alliant RL-26 Just wanted to confirm these mag fed without issue (they did) and hoped for 2720ish Fuck me.
Per Gordon's this should've been 2735fps & 62K psi
Based on Speed below these were probably 70K psi.

130 Berger AR Hybrid OTM seated 2.820" Using Vit N550
Gordon's is typically close with Vit N550, but not this time. Predicted speed for load below was 2777 @63k psi.
Someone must of poured extra Nitro in this lot.
Based on speed this was probably 75k psi giving these Fury cases a workout.
I'll revisit this powder -2gr and see how it does.

Hornady 100gr eldm-VT's Using Alliant RL15.5 seated 2.820"
Gordon's prediction for this load was 3100 @63k psi
Reality 65k psi & no sweat for these cases. They held moa @100 so I sent 5 at 600y steel. Saw impacts but no trace. Dam things get down there quick.

Am very curious. . . how many rounds of these hybrid cases have you fired in that barrel?

Have you inspected the chamber with a bore scope to see a ring developing where that steel head and brass body junction is?

New 6mm Advanced Rifle Cartridge

No doubt a lathe is the best tool to use.

I'm not waiting on major tool so I just ordered one from Hornady.
It will be off from my chamber but I can take measurements and do the math.

I don't plan on sucking up to the lands even if it were possible which I think not with the aeromatch 105 in a magazine dimensionally impossible I think 🤔.

Touted as jump tolerant which as I have found not the norm from Hornady.

Columbia River Gorge a bit over a week ago. The scenery in the American west is just beyond belief!!

Load development help?

Its not the scale thats the issue its my fingers tend to overshoot by .1-2 then i have to get some out and go again.
Here's a trick you might find useful with that Hornady trickler you're using:

Get a large diameter clear drinking straw and cut 1" inch off. Press that 1" piece of straw onto the trickler tube ~1/4". This clear piece of straw makes it easy to see how many granules of powder are about to drop into your powder pan, making it easier to control. In addition, rather than setting the trickler flat on the surface, you my put a piece of folded paper under the front to give it a little tilt and reduce the flow coming out of the tricker's tube. Then, with all this, rather than turning the the tube to move the powder out, use your finder to tap (vibrate) the tube where you can actually control it dropping a single granule that you see coming to the end of the straw. This is the method that's worked really well when I'm using my manual tricker like yours.

But i loaded all to 46grn according to the scale. I just need to practice being more precise.
Hmmm??? Are you loading 56grs like you said in your OP or is it 46 grs? If you're actually loading at 46 grs for an -06, the fill for those cases are too low. 56 grs sounds much better, especially as you've stated that you saw a published max at 58.2 grs.

3.38 is what im loading to. And i believe its just behing the lands as i dont get a mark on. The bullet and the bolt closes without force ( with firing pin and extractor removed) there abouts.
Hmmm??? It doesn't sound like you found where the lands is, where you know how far off the lands you're at. If this 3.380 is right at the lands, as you suggest, then that's increasing your start pressure by quite a bit to where you're probably at or a little over pressure using 56 grs, which your chrono velocities suggest to me.

It's ok to be close to the lands, just be aware that an increase of start pressure can skew your velocity comparison to published load data. And as the throat erodes, that's going to cause the velocity do decrease sooner than you think.

Its a 22 in barreled rem700bdl from 1978

Hodgdon says max is 58.2 for the powder.
But im also not inclined to try to max out velocity. A consistant 2700fps would be good enough for me i think for shooting at most distances. Im more interested in getting as good a group as i can velocity and pressure isnt my main goal.
With the info you're providing, that 2700 fps out of a 22" barrel with that round sound like you're already pushing max pressure.

That said. I do plan on putting a 25 in barrel with a #5125 lothar walther contour ( its going to be krieger but i like those dimensions) and blueprint action and pillar snd glass bed sometime before next years hunting season. So ill have to redo the process. But im approaching this as a learning experiment. And i appreciate all the help you guys have given me and continue to do so.


As to the photo ill have to get it monday afternoon as i have a 24 hr shift tomorrow and i work pt monday.
A Krieger 25" barrel sounds like a nice project. :)

Chrono expectations in a semi vs bolt gun?

Example bolt gun runs ammo A for 50 shots with velocity from 1100-1130 (30fps) spread, AR runs same lot ammo but with a 90 fps spread 1025-1115 (90fps) spread. There's no way the AR can group as well at distance just due to the velocity delta. However the more interesting question is what would cause this. Lower velocity sure, you have to cycle the action, but why 2-3x the variation in speeds? It can't be the ammo because it gets 1/3 of the velocity change in a bolt gun, so in my brain it has to be something that's AR platform specific, or a specific issue with that gun, that's causing 3x the pressure/velocity variation shot to shot. Poor ignition/light strikes, poor bullet sealing, inconsistent unlocking etc.
I actually do shoot the same lot ammo in both my 22” Bartlein AR And my 26” CRB comp/impact/foundation bolt gun (federal 77gr smk fgmm) velocity drops a bit and yes SDs grow ( goes up about 5 fps). Is accuracy the same, no, but fairly close. My bolt does ,55-.67 average. My 22” heavy ( .936) Bartlein JP upper does .75-.85”. Is this due to inherent quirks with the AR platform maybe some but mostly me not shooting the AR often enough to remember how to ride the recoil better.
