What about H4198?

It’s great - just ran out-
Developed a load for N120..
never looked back!!

 

[Gabe22BR]

Mr Magoo swapped out his 1” tube 6.5-20x leupold-

Installed his NF comp onhere’s 5@100yd
Then went to 200yd to see where the hold was-here’s 5@200yd

& 300yd is just as huge!!!


Guess I’ll load up 50rds now, about burnt through these 25 rds sight in & plinking sweet gum balls..

 

[Gabe22BR]

What about H4198?

H4227 is awesome!!! My 1/2lb not going too far, still loading 221FB w/ it…
I had no problems using H4198..actually like it -I did not try either IMR 4198/4227…

 

[Gabe22BR]

19.16gr powder in case (N120)

Drop tube on 1 case the other was just the funnel-

I believe case density comes into play…

 

[Gabe22BR]

So I just took my loaded Cooper 39gr BK loads, I worked & loaded last yr….thinking they would be a starting point, possibly already set up.
19.9gr LT32 - 39BK .002” jam-205M primer

I played w/ the seating depth some- nothing to prove on there- played with the powder charges- same thing- didn’t realize I already had the load…

 

[Gabe22BR]

I’ll be sticking to the 32gr pills in this rifle as well.
Just waiting on my scope to come back, then it’ll be ready…

 

[Gabe22BR]

I got a few 40gr Bib I might work up a load for.. just to see…

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
View attachment 1631574View attachment 1631575
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..View attachment 16340265@100yd -target… View attachment 16340285@200yd- target

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

Years ago, late 1980's I believe, there was an articlee in Precision Shooting about a .221FBI.....221 FireBall Improved. Haven't been aware of it since then until now. A 20 Vartarg Improced seems the perfect .20 cal. Yours appears to hold a little more powder, but also more trouble to make. A friend rechambered a so-so shooting Rem. 700 / 221 with my reamer and it became very accurate. And made brass from, I believe, LC .223 brass....much stronger. Hotter loads and picked up a good amount of velocity. If I were wanting to go .20 cal.your cartridge would be my choice.

 

[Gabe22BR]

No problem to make-
221fb form die that is set .004” long for shoulder , trim little long
Run in my Blaine plate to get all way to 20 cal to shoulder
Load & fire-

I set my shoulder in the 221FB form die to keep it tight against BF…

 

[Gabe22BR]

An Awesome guy sent me some perfect brass for my new CZ barrel-
#1- is to deburr the flash hole
#2 is to run it through the 221FB form die- push shoulder back to a “crush fit” in the chamber-

 

[Gabe22BR]

Then
Got trim closer to length-come back deburr, chamfer

 

[Gabe22BR]

Next is to use the Blaine Eddy plate
Going from 22 cal to 20 cal-
I use mineral oil
Just spin them down to 20 cal

 

[Gabe22BR]

Now I’ll trim them to finial length-my max OAL chamber length is 1.4320”-
KNOWING the brass will shrink as the 40* shoulder is formed
- the shoulder blows forward & outwards-

Also I I annealed the cases after this stage-

 

[Gabe22BR]

Now I size the neck down in my die to .229” for the expander to set it- for turning-

 

[Gabe22BR]

Now for a quick bath ( acetone Or lacquer thinner) - to get rid of the shavings & chips- and lube-
Little puff of air to dry them out-

 

[Gabe22BR]

Now for turning-
And ran back through the sizing die to squeeze nk back down…
One last Bath-

 

[Gabe22BR]

Bath-

I try to touch the shoulder with the cutter in this state-
Even thought it’ll blow to 40*- this will help keep the dounuts at bay

 

[Gabe22BR]

Now to anneal-

Burn one for analysis- to get a code
Then use the code to finish the rest-

Kinda funny how this code is the very exact same for my Lapua 221FB & Lapua 222 brass I made into this same case…
let them cool off-

 

[Gabe22BR]

Now I chamfer & deburr 1 last time-
I use a Redding primer pocket cutter- not sure of the factory set depth- it doesn’t even touch Lapua pockets… so I’m pretty sure it doesn’t take much out, just true it up mostly

 

[Gabe22BR]

Now to prime and load them-
I’m using IMR 4227 -15.2gr
The Supertrickler makes easy work

Don’t be eyeballing my custom cup.. I made…


I use Wilson arbor dies- cut with my reamerone can make a dummy rd to find the lands-
Therefore I can set my die up to jam the bullet .005” into the lands- for futher assurance of keeping the cartridge tight in chamber…
