Underwood 200gr 10mm Hard Cast

Taterhead · March 05 2015 10:03:26 AM MST

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.

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.

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 ${$default_shocked_smiley}$

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.

Intercooler · May 21 2015 02:55:48 PM MDT

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.

4949shooter · June 03 2015 01:59:02 PM MDT

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
