Here's a pic of the new 20 Tactical cartridge flanked on the left by a .223 and on the right by a 17 Remington. The .223 and 17 Rem employ the same 23 degree shoulder whereas the 20 Tactical has a bit more improved 30 degree shoulder. To make a .20 Tactical round, you simply run a .223 through the .20 T size die and you're good to go. General balistics are as follows:

.223 55gr 3380fps 1396 fpe
.20 T 33gr 4300fps 1355 fpe
.17 25gr 4120fps 944 fpe

All from 24" barrels.

I don't want this post to turn into a huge debate over which one is "better", I don't really care. The .20 Tactical is new and unique and thats good enough for me to want to play with it. Kinda like playing with a new woman.....

Tromix will have these available in about 30 days. They will most likely be configured like the other Tromix TackHammers. You can see them on the website if you like.

Send me one (for free! ) with lots of ammo (for free! ), and I'll do some ballistic gel tests!

Yep, the .20 caliber bullet is a Hornady V-Max. The other options are the Berger bullets. They make them in 30, 35, and 36 grain weights. Weidner's carries the entire line of Berger bullets, so it's no problem getting them.

Not sure what the point is. Other than chumming for business, maybe? That's perfectly legitimate, capitalism is a great thing. Just what problem does ".20 Tactical" solve?

Edited to add: if you didn't want a debate over which is better, why did you title the thread "New .20 Tactical vs .223 vs 17 Rem" ???

The reason I don't care for debates on this board, is that most individuals simply try and convince others that whatever they personally own is the "best" and whatever someone else may have, sucks.

You are correct, there is no point in that.

Tony,
I ain't looking for a debate.

I am however interested in the .20 tactical for potential use in varminting,and taking furbearing critters with Minimal pelt damage.

Just from the figures you posted I can see that trajectory out to 250m or so would be as flat as the .17 and likely a bit further because of higher mass,and energy levels are higher.

You mentioned that Berger and Hornady make bullets for it but I havn't found hornady .20 cal bullets in the past.Is this something new from them in support of your new pet?

Either way,color me interested in the external ballistics,and curious about the terminal on Coyotes,and Fox.Anybody have any field time with it on critters??

Thanks.

My ballistics program is TU at the moment, but usually you will find the initial launch speed is more important than anything when you are only shooting 400 yards or so. It's only past that, where the high BC slower bullets start to take over in the bullet drop department. Out to 400 yards or so, the 20 should be extremely flat. That 4300fps launch speed from the 20 should prove very flat and have less bullet drop than the 17 or the 223 out to 400 or so yards. In the wind, time of flight is fairly critical and that 4300fps speed should again help some, but you only have a 33gr bullet, and that is working against you so wind will still be an issue.

For varmints out to 400 yards, without wind, the 20 should fare well. If the distance is past 400 and you have some wind, I would go with a .338 Lapua or the big 50.

The local shop here has the Hornady 20 caliber bullets on the shelf, so availability should not be a problem. The real disadvantage I see with the 20, is simply the lack of range in bullet choices. Right now, there is only 30-36gr weights whereas the .17 has 15gr to 37gr and the .223 has 40-80 or so. That limits the application of the new 20 to a narrower window of application than the .223.

The bolt action varmint guys have been working with the new 20 for quite some time. You can see more info at www.woodchuckden.com

What about throat erosion with the .20? Is it available with a pre-ban config upper? I take it feeds through regualr mags?

I imagine the throat erosion on the 20 would be higher than that on the .223 and basic barrel life may be a bit shorter. If you plan to run 10,000+ rounds through your varmint gun every couple of years, I would probably just stick with the .223.

The 20 will feed fine from standard magazines. I can make an upper in any configuration you like, pre or post.

SSK Industries, as well as Les Baer will have AR's in 20 Tactical in the near future as well.

.50 bmg on a varmint?

Tony,
Does this mean your offically back in buisness?

Yes.... www.tromix.com
Back up and running.

I just opened my mail, and the new 20 Caliber loading manual has arrived. There is one ballistic chart that shows the Hornady V-Max bullet leaving the muzzle at 4325fps, sighted in 2" high at 100 yards, it ends up 3" high at 200 yards, 1" high at 300 yards, and 5" low at 400.

Comparing it to a 55gr .223 at 3300fps, you have to be 5" high at 200 to end up dead on at 300 and you are 13" low when you get out to 400. So with both rounds basically set-up dead on at 300, the .223 will be 8" lower than the 20 Tactical at 400.

Of course the .223 is going to hit a lot harder when it gets there. At 400 the .223 is going 1832fps with 768fpe, whereas the 20 is at 2552fps, but is only packing a meager 477 fpe.

Tony,
Thanks!
I am mostly concerned with 200m and under,and the oddball 300m Shot on "Sir Charles of the wood".
Thanks for clearing that up.
The trajectory is impressive.Especially for those that 'Chuck hunt in semi built up areas.

No need for the .338 Lapua.I've got a .338GT for such silliness,and have yet to find a varmint that needs the killin' a Kudu takes.

Been fussing with the idea of a Corbin Swaging outfit since this years bonuses were announced.
Unless the kitchen project spills over,I just might just go oddball again.
No promises,but it's nice to know I have options out the ying yang.

Thanks for the reply.
Good luck with the resurection,and godspeed!
