20-221AI

[Gabe22BR]

New killer out of the barn !!!
Target looks promising, still have to work few gremlins out..

CZ 527 20-221AI
Preferred barrels 1-11” @ 20” #3
WS2 coated 32gr Noslers @ 3926FPS summer load in the 35* temps..
B&C stock , action full bedded as can be

It’ll find a home in a tractor, combine, semi truck, gator, jeep.. where the other one isn’t…

This was originally a 221FB… it does feed find from the mag.. had a few hiccups from the start, since action was new..little polishing the claw, look out !!! It’ll run now..5@100yd -target… 5@200yd- target

Yeah I believe it’s gonna shoot.., feed, extract from the 221FB magazines…

Any chance of a side by side photo of your cartridge and a 20 Vartarg?

Ok

One of my absolute favorite PD cartridges, too. I call mine a 20 FireBlaster but it's just a 20-221AI also. A 32 grain bullet at 4,000 fps creates interesting downrange results. Definitely has the VT by a couple hundred fps and just as accurate.

Have you ever thought about shooting the 40 grain VMAX

Please describe your forming process for the 20-221ai

No offense- no I don’t use them… Hornady makes great gifts for other shooters- just not here-


I do have a 39BK load, I like as well..

I run 222 brass into my 221FB form/trim die-
Deburr
Chopsaw the neck
Run them into my Blain Eddy plate down to 20 cal
Giaurd trim
-depending on brass- nk turn might be necessary-
Anneal brass
Size in FL die set .005” long
Load & fireform brass

Anneal, size, trim .003” of chamber 1.4320”-.003”=1.429”

I found the 32gr Nos. Likes .093” jam in mine-
39gr BK likes a .005” jump..

 

[Gabe22BR]

Dang switching winds !!!
I’ll do it again on a calmer day.. not raining …

Not trying to be smart, actually curious, is there a benefit to this round over the 20 practical? I get 4000 fps with 32 Nolsers with my practical. Don’t get me wrong I have calibers just because I want them but wondering if there is something about this that’s different.

 

[Gabe22BR]

Maybe less powder for the same speed ??
Possibly more efficient??
Lot less brass trimming ??

What was your speed with the 39

 

[Gabe22BR]

LT32-19.9gr 39BK 3515 fps

 

[Gabe22BR]

Now to see if it repeats..grs listed upper rt corner- primer used in Lft, velocity @ rt bottom

100yd test

Here is 222Rem data with 40gr bullets from the same 20in bbl. Factory brass, just load and shoot.

The big difference is annealing. Trying to anneal the necks of 221 length cases without softening the case head is very tricky. Less difficult with the 222.

 

[Gabe22BR]

Yep,
Like I said efficient little case..
