20 Practical N133 Varget?

[jpx2rk]

The ones I was using were the MidSouth shooters supply 34 gr FB. If like the .224 bullets these are made by Nosler. I've had good accuracy with the .224 diameter from Midway and MidSouth 55 gr HP.

I've shot them in 204R and 20P with 12T, 11T and 10T. Just never got them to work for me. And I was only looking for prairie dog accuracy.

I've been using the 34g Dogtown brand, and getting sub moa w/ AA2520, 450's in Frontier brass, 2.20" oal , 25.0 - to 25.7g powder charges. Not as accurate as the 32/40g Vmaxes, but "good enough" for pdogs and sage rats IMO. LOL

I'm running 39 gr SBKs at a measured 3870 fps using 25.5 gr of H4895, BR4s, IMI brass. Barrel is a 26" X-caliber 11 twist 3 groove. Here's a pic of the first groups I shot during load development. Five different H4895 charges from 24.9 gr to 25.7 gr, in 0.2 gr increments. Target was at 100 yards

Not to hijack the thread but whats a resasonable velocity for 40s out of a 24" barrel? How hard can you push this cartridge?

Generally, even though a 20P has a tiny bit less case capacity than does the 204 Ruger, a 20P will nearly, if not, match the velocity of the 204 Ruger in the same length barrels.

Some of the 223 brass, Lapua for an example, is some pretty tough stuff and can take higher pressures without giving up primer pockets so don't be surprised if you hear of velocities well above that of a 204 Ruger, just know when you hear about those speeds it's happening at higher, sometimes much higher, pressures.

At reasonable pressure most 20 Prac. should be able to reach 3700-3800fps with 40's out of a 24in tube.

I shoot the 32 Vmax with Ramshot exterminator, this combo works well and loads good through a progressive.

Hi all. Just finished my first .20 cal build in 20 practical. New to the forum as I was searching for experienced wisdom and recommendations / load recipes and this was the most recent .20P thread.

I have my first velocity ladder for 40gr vmax's worked up using headstamp sorted / fired brass, BR-4s & N133 (22.0 thru 24.5gr in .05gr increments). I'm pretty comfortable with this work up as I can find multiple, similar N133 recipes in various places for this load.

But on another hand, I picked up 2# of N120 as another .20P shooter at a "gun-show-conversation" recommended it & 8208 as "other" good candidates for a 32gr vmax load... and now I am second guessing the 120 purchase. I cant find any 20P data utilizing N120 anywhere. I can however find VV & hornady loads using N120 for .223, and 222, 221FB... so...

I've been kicking around giving a ladder a test run with the 32 gr vmaxs, maybe even using CCI 450's to assist with a lower case volume load, but just have this feeling to be wary. Seems N120 can pressure spike quickly.

Thought I'd reach out for some experienced input. I would welcome any and all feedback.

Attempting to add a photo of my yet-unfired .20P build. It's a 26" with 1:10 twist.

I know that I am seven months late to reply to this, and you probably already know the answer, but I have used N120 with CCI 450s and I was not impressed at the accuracy nor the velocities I was receiving out of my rifle. However, I only use CCI 450s for my 20 practical loads. Some people think that it’s silly or over the top, but that’s what works best for me.

RL10x was best for velocity I found. 8208 would have been good too but never tried it. H4895 was my other choice 40gr bullets around 3650 and accurate as sin. Speed isn’t everything. If you want to go fast use 32’s. The 40 noslers will hold together more than vmax or sierras.

With AR and White Oak Armament 24" 1:10 twist .020 freebore
Hornady 32 Vmax, N133 best load 24.0, 3850 fps. LT-32 23.3 3890 fps, and 8208XBR 24.5 3705 fps.
Nosler 40 BT, 8208XBR 25.0 3644 fps, very accurate load, low SD's
Hornady 40 Vmax, 8208XBR 25.0 3650 fps, most accurate load, all groups typical from .23" to .45" groups.

There are a lot of good powders that can shoot really good. Between my rifles and those of my friends who also shoot .20 Practical, we have run through a lot of bullets and powders over the years to find the magic. If maximum velocity is what you want - continue to lean towards the slower powders. If the best accuracy is what you yearn for, I'd also try some of the faster powders, specifically Accurate LT32. With 32 and 40 V-Max and 39 Sierra Blitz King (our preferred bullets), the LT-32 is hands-down the champion powder in all of our rifles. H-4198 and H-322 runners-up. We all get under 1/3 MOA, using very heavy, long-barreled, home-assembled A/R's. Good luck!

Have a 20 Practical bolt gun project in the works, Tikka with a 11-t Bartlein, and I'm looking to gather some loading components, I know from what I've read the 20 Practical shoot well with a variety of powders bullets ect., shooting for accuracy and all around proformance, I'd like to know from some of you "experienced" 20 Practical Shooters out there, what is your "preferred" powder, bullet and primer choices, thanks fella's

I built one..it was a was incredibly accurate..I regret selling it..it was kind of boring to shoot with in 100-200 yards...that thing hit what ever you point it at..its just enough weight to buck the wind, yet lite enough to cook down range..with little powder, very little recoil but man was mine loud..I had an 18" barrel..x-barrel ..the .20 practical has a very long throat so finding the perfect COL is a good reason to keep clear reloading note ..and remember to keep that in your testing..it makes a big difference..if I remember correctly..the bullet will barely seat in the case when touching the lands...
Here is a link to some chatter about the .20 practical you may enjoy, and find helpful..
Safe shooting and take it slow..a little goes a long way with the .20 cal bullet loads..
Just my thoughts, and experiences

I am slowly puting together a 20p. I will be loading with N133 to start with. Really want 40gr noslers varmint ballistic tips bot nowhere to be found. Next would be 35gr bergers, but also gone. I do have some but saving for my 204r. So will be between 32-40gr vmaxes since i can get them. Im hoping this powder works well. Going to get a 1:10 twist barrel.

 

[RabbitSlayer]

I have a pound of n133, so I have looked at a lot of data. Anything I have looked at for 204 and 223 the velocity is low. That may not matter to you. I sold the 204 to build a heavy barrel and sporter on a tikka both in 20 practical, so I am interested in your findings. From my research, 8208, h4895, and benchmark are what I am going to try. Exterminator is cheap and worked good for me in 204 and 223 if you don't care about temp stability too much. The real problem is good luck finding the powder you want to try!

 

[7887mm08]

8208 with sierra 32 gr blitz kings are my go to load

 

[jpx2rk]

I tried some X term and H335 yesterday in a Urban full bull 20P with some 34g Dogtowns and got some decent groups, the upper powder charge weights seemed to be the place to be, but no MV yet.

My load for my 20P was 25 grs. of H-335-CCI primer-40 gr Vmax-LC cases. Barrel was a Kreiger 1:11 at 26".

 

[JB10]

Im not after high velocity just decent accuracy. I do have several powders i can try also. I am keeping all my H4895 for my 6br though untill its around more. Think i got n133, w748, h335, cfe223 i can play with
