I'm building a 20 Vartarg for a customer. First 20 cal I've done. Anyone have any experience/load data with this round? This will be the fitted neck chamber.

If you have access to loaddata.com, they have a reasonable list of loads.  This is the only place I have found loads published except for an internet search. 

I am having a barrel made in this caliber for my T/C Encore.  I have made up some ammo for testing but have not shot any because I am still waiting on the barrel.



From Varmint Hunter Magazine, Oct-Dec 2008,

berger 40 grain
aa1680 16.0 grains
cci sr 450 or cci br-4

sierra 39 grain
aa 1680 16.0 grains
cci br-4

berger 35 grain
h4198, 18 grains
cci sr 450

Look on Hogdon web site.

Let me know if you need more help.

TJ

I've only shot the 32gr v-max and the loads I like are:
19 gr Reloader #7 @ 3690 fps
20 gr H322 @ 3565 fps
and the one I like the best is:
18.5 gr H4198 @ 3680 fps
hope this helps get you started

I have been shooting a 34 grain Midway hollow point with 20.0 grains of Data Powder 2200. I have only had the gun out on one trip. It exceeds all expectations. I like it so much that I wonder why I did not figure out that I needed it a long time ago. I shot about 300 rounds through it with my test loads and will stick with that load until I use up the 8 pounds of powder I stashed a long time ago.

Very accurate, relatively inexpensive to shoot, blows up Prarie Dogs better than the .17 Mach IV.

Comes highly recommended by me.

Thank you Todd Kindler for inventing this gun.

I personally own two 20 VarTarg rifles, both Coopers, (a Model 21 Varminter rebarreled by Cooper from 221 Fireball to 20 V/T, and a Model 38 Montana Varminter). This cartridge is simply AMAZING! I have used both rifles in long range precision matches in Tucson, AZ and have made believers of many competitors, including our custom 6mmBR shooters. The farthest targets in the Light Varmint class are at 426 yds, and they present NO PROBLEM for this little guy. I call it Mighty Mouse. In 2008 before I moved from Tucson I started a lady friend shooting the matches with one of the 20 V/Ts, and she was placing 2nd and 3rd herself after only 4 months. We also took one of the 20 V/Ts with us to open our PD season June 2008 near Seligman, AZ. My farthest kills on that hunt with the 20 V/T were made at 472 yds and 455 yds respectively. My lady friend managed a kill at 450 yds. Our PDs are Gunnisons rather than Black Tail or White Tail, and are not much larger that a man's open hand in most cases. I know there is always discussion about 39/40 grain bullets in a 12 twist barrel. Both my Coopers are 12 twist and I use 39 Sierra Blitzkings and 40 Hornady V-Maxs exclusively with NO problems at all on little bitty targets at long range. I have even let 2 acquaintances of mine, who had never seen nor shot my rifles before, shoot golf balls (1 1/2" dia) at 221 yds with unbelievably accurate results. You just can't go wrong owning a 20 V/T AND shooting the heavier bullets!!! My load for either the 39BKs or the 40 V-Maxs consists of 17.7 gr of H4198 (mild) in fire-formed 221 Rem F/B cases lit by Federal 205M primers. I have some cases that are now on their 18th reloading cycle with only a random, occasional split neck, and some minor loosening of primer pockets over time due to expansion after 17 previous reloads. I am hoping that all 20 V/T owners who are skeptical about heavier bullets in the 20 V/T will try the 39s or 40s. At looonng range they will amaze you with their performance!! My farthest target hits to date with my 20 V/Ts have been on our Heavy Varmint class silhouette targets (9"H x 5"W) at the extreme distance of 565 yds. In reasonable wind the 20 V/T can make that distance with NO PROBLEM AT ALL!!! Hope this helps.

Good report ae35Gunner.I believe the 20VT will continue to become more popular among varmit shooters

I'll second ae35gunner's report from my own personal experience.  My 20VT is built on a Remington 700SA with a 24-inch Pac-Nor barrel, 1:12 twist.  Gre-Tan Rifles out of Rifle, CO did the work.  I also shoot a 39-gr Sierra BlitzKing with outstanding results, and here's my load:

19.3 gr VihtaVuori N130
WSR primer
R-P .221 fireball case

It chronographs a shade below 3600 fps (3597 fps) under Texas gulf coast conditions. I use "The Terrific Twenties" reloading manual by Todd Kindler of the Woodchuck Den.

My longest confirmed kill on a prairie dog is 543 yards.  There was a slight crosswind, and it took 5-6 shots to get the windage right, but once I did, it was bye-bye prairie dog.  On a coyote hunt, we got into a bunch of feral hogs and I took 5 hogs out of the group using only 6 shots - 2 of them sows weighing between 150 and 200 lbs.  I consider the 20VT a bit light for hogs, but place that 39 gr bullet just behind the ear and that hog doesn't know what hit him!  Longest shot on one of the hogs was just a little over 200 yards.

My daughters can routinely hit my steel prairie dog target at 300 yds, and they don't shoot all that much.  It's an absolute blast to shoot!  Combine the accuracy with the lack of recoil, and you have one fun-to-shoot round!  smile

I 2nd, 3rd and 4th everyone's comments about how good the 20VT is. I bought a Cooper Mdl 21 about 4 years ago and when I saw the target they included with the rifle I was pretty skeptical, but not after close to 2000 rounds through it, I think this gun and caliber is better than great. I shoot mostly Belding ground squirrels; a big one is maybe half the size of a prairie dog, and use mostly 32gr Blitzkings. After a good day of 300 to 400 targets my shoulder doesn't hurt and my head doesn't ring; I couldn't be more comfortable.

The most consistently good powders in my rifle are H4198, Reloder-7, VV N130, H322 and H335. 4227 and 2400 shot a few good groups but weren't consistent, and 1680 and 5744 were pretty lousy IN MY GUN. Berger 30gr bullets were the most accurate but at the price just a little too steep for rodents.

My biggest problem is that now there are so many good powder and bullet combinations to try out that I'll have the gun shot out before I'm finished playing. But it's fun though!

P.S. See my comments / questions about Fireball cases on the Cartridges, Hand-loading page. How common is this problem?

I recently tried Midway Dog Town 34 grain hollow point bullets in the .20 Var Targ and was very happy with them on Prarie Dogs.  Dead is dead.  I have just purchased some Mid South bullets and expect to be happy with them too.  I shoot so much that I need to be economical with what I buy.  I have nothing against the top end bullets but think one can be happy with large volume shooting with the lower cost bullets. 

This gun is amazing.  Death from afar. 

The only complaint is the cost of the brass and I anticipate someone besides Remington will start making it because it is going to be very popular. 

You can make the brass out of .223 or .22 cases but that is pretty tedious.

(Sorry about misleading anyone. My other posting regarding the brass is a new topic in the 20 Caliber forum)

I have about 400 test rounds with various powders and bullets (including Dogtowns) to try out but can't seem to get my lazy butt out to the range. Gotta get my priorities straight. But I have tried some Dogtowns on squirrels and certainly can't see any difference in minute-of-rodent accuracy. Might not be quite as spectacular as V-Maxes or Blitzkings, but, like you said, dead is dead.

I have four Cooper rifles, three Model 21s which are chambered in 223 AI, 20 Tactical and a 221 Fireball that I had Cooper rebarrel to 20 VarTarg at a cost of $325 in 2006. I also have a Model 38 chambered in 20 VarTarg. In 2007, while Rob Behr was still the customer service manager at Cooper Arms, they rebarreled my 20 Tactical (which I had purchased in 2005 and had shot out in 3 years) at no cost to me. The current customer service manager is Mike Hudgins. You should contact him and discuss your options. For everyone's information, Dan Cooper sold Cooper Arms to Hugo Vivero, the owner of Wilson Arms which manufactures the Wilson barrels that all Coopers use. Coopers are GREAT, EXTREMELY ACCURATE rifles that are made right here in America (can you believe it). They have a reputation for standing behind their products and Mr. Vivero deserves our support.

 I have 3 Coopers, all in Montana Varminter, a .221 Fireball, a .17 Mach IV, and a .204 Ruger.  They are all excellent rifles and highly accurate.
