Noticed this on their site this morning.
I must be missing something never saw this configuration before.
Anyone else know about it?

I will have to grab some.
Git some!!
I probably will! These don't look to have the Meplat of the Beartooth.
Maybe they will feed better?
Should be an interesting comparison to the DT 200wfngc's
Nice anti bear round. This matted to a 6"+ barrel would be good insurance.
Ive never had a prob feeding the doubletap in my g20sf
Got them today and a new warning label on this box:

Smaller Meplat than the Doubletap Beartooth 200gr or Granite 200gr. Looks to be the same as the RimRock 220's:

Wonder why Kevin went with this?
I have a box. Just because.
Hmmm... I thought these were 1200 FPS rated.
10mm Underwood 200gr Hardcast
EAA Limited Pro 4.75" 1174, 1194, 1199. Average = 1189 FPS/ 628 LBS
EAA Super Match 6" 1227, 1233, 1210. Average = 1220 FPS/ 661 LBS
Short of the flap rating by a good bit for Underwood.

1250 FPS out of what barrel?
That would be a G20 4.6" barrel. These would be in the 1150-1160 FPS range in that length.
I see that. I would let Underwood know for sure.
Interesting that they are running slower? ???
Yeah that's quite a bit off the flap for Underwood... might understand the difference if we were talking about the 220gr and the different powder (simply because of the lack of case volume) but with the smaller projectile it seems there'd be enough room to make up the difference... Unless everything is being down-loaded for the time being?? Anyone heard anything from Kevin about the powder change or velocity ratings in question?
Load the ammo we really want underwood this isn't it.
You want Beartooth? The order quantity is huge and from the sounds of it Doubletap has the rights to those.
Underwood has been doing everything right. If they don't have access to Beartooth so be it.
They will do their best with what they have.
And I was skeptical of them in their early days. Right? Intercooler remembers the debates we had here about them.
Yea... Thanks for watering down the ammo ;D
Well any flatpoint with a metplat of .32" would make me happy. Other companies make them like magnus bullets i think has sum in 180gr. Beartooth cant be the only ones making these. But i guess thats why reloading your own is so cool you just make your own.

I'm not sure about that one. Doubletap's WFNGC is a closely similar profile, but they are not the same bullet as Beartooth, and they haven't loaded the Beartooth for at least 5 years. I communicated with Mike McNett about 6 years ago when they transitioned to insourcing casting of that bullet. He claimed that they are identical, but they aren't. I have still have a few both on hand that aren't loaded. The lube grooves are different, the crimp groove position is different, and the size of the flat point is slightly different. I've hand loaded both, and the BT is better quality.
My guess is that UW wouldn't go with Beartooth simply because they are really expensive, and BT might not be well equipped to function as a wholesale commercial supplier. Beartooth states that they are not really into volume discounting.
A Beartooth at a hair over 1200 fps is a GREAT load.
Do you have a picture of a 200gr Beartooth? We have the Doubletap round in the pull-downs. I was always told and people coined the reference to Doubletap using that bullet.

I can take a pic tonight.
The Beartooth and Doubletap 200 gr WFNGCs. The BT is on the left of each pair. Note that the DT is missing its gas check. I pulled this bullet from a workup ladder that I decided that I'd gone far enough. When I pulled it, the gas check stuck in the case. Note that the crimp groove on the BT is a bit low, and the DT is a bit high. These are seated at 1.26". Of course the crimp groove is a non-issue in 10mm since we don't roll crimp.

Just for fun, here is what happens when you shoot into water jugs with one of these loaded to a bit over 1200 fps. The first 3 jugs were wasted. Note how far the 1st one got tossed. You can also see how there was a footprint of the water jugs scoured into the space where the jugs were sitting. This is easily the most impressive display I've seen with any 10mm ammo. The bullet continued through SEVEN full jugs before drifting right and exiting the back right corner of the 7th and going into low-earth orbit. I have meant to repeat this test for a few years, and stack jugs to the side. I want to see just how many this will penetrate. I haven't captured one yet.
FWIW, I spent a day doing side-by-side testing of the 200 XTP and WFNGC. Both loaded to a bit over 1200 fps. I shot at all kinds of unscientific media. There was such a huge difference in carnage brought by the WFNGC vs. the XTP. That blunt profile is a hammer.

PBR 200gr Beartooth
(http://i1086.photobucket.com/albums/j441/_The_Shadow/IMG_0095_zps98f4efd6.jpg)
Doubletap 200gr... I guess I should change the sheet to their own bullet?
(http://i1086.photobucket.com/albums/j441/_The_Shadow/IMG_0100_zpscc6435ce.jpg)
The easiest way tell them apart is that the BT has 2 lube grooves, and the DT has one. I haven't purchased DT components for a few years so I dont know if they've changed. In fact, I don't see the component available on the DT site at this point. Looking at the photo loaded ammo on the DT site, it shows the DT bullets that I'm familiar with. You can tell because you can see the exposed crimp groove above the case mouth. With the Beartooth, it is not exposed when seated in a10mm case - even when seated long like in my photo below.

Way back, DT did load BTs bullet, and I think I remember correctly that they used the name "Beartooth" on the box at the time.
I will change the sheet to Doubletap bullet since that seems what is there now.
I'm admittedly out of the loop a bit with respect to some of the documentation that is being done... to what sheet are you referring, if I may ask?
This one I have been working on for years :o

Nice. You're a man after my own heart. As a CPA and data guy, I can appreciate collecting and collecting data in a useful format.
Any reports of these yet? Was thinking of trying them. Looks like velocity is down.
Slightly when I tested those. Things might have changed by now though.
I am going to get a few boxes to try out
Hi Everyone, 1st Post. Been on here for a while digesting as much as I can. Shot a box of this 200 grain hard cast this weekend in my G-20SF with stock length KKM barrel, #22lb RSA.
Chrono'd 15 shots. Had 1170fps low, 1247fps High, and 1205fps Ave. Only malfunctions was two times the slide did not completely go into battery while my wife was shooting weak handed. Just tapped the slide and good to go. No FTF's. Probably will be our woods carry round. . Thanks, T
Very similar to what I saw. It doesn't look like these will hit the 1250 FPS they put on the flap.

That's a pretty big spread.
It could be unlocking.
Could be yes.

I think you are saying the slide is unlocking to fast? Maybe a heavier Recoil spring might lower the extreme spread? I am using a 22#ISMI and I read that some folks claim they are rated a little low. Otherwise the accuracy was acceptable, and I am OK with a 200HC at 1200fps. Thanks for your help! T
You might want to try a 22 or 24 pound RSA.
You can get them from Glockstore or Glockmeister.
In my G-20SF I use a Non Captive RSA from Wolff, the reason being is it applies more pressure at lock up... ::)
Glock 20SF spring test Wolff Gun Springs 22lb RSA installed
It takes 6lb 4oz to start the slide to move from the locked position
Full retraction at 22lb 9oz at lock open
22-Slightly over a pound difference 1lb 1oz to start the slide to move from the locked position
22-Slightly over a 2 pound difference 2lb 9oz at lock open over factory
Glock 20SF spring test Wolff Gun Springs 24lb RSA installed
It takes 7lb 6oz to start the slide to move from the locked position
Full retraction at 24lb 1oz at lock open
24-Slightly over a pound difference 2lb 3oz to start the slide to move from the locked position
24-Slightly over a 6 pound difference 6lb 1oz at lock open over factory
Glock 20Sf Factory spring test
It takes 5lb 3oz to start the slide to move from the locked position
Full retraction at 18lb 0oz at lock open
