My Handloads using those 260 grain Devastators as tested by you showed some good results as compared to the DT stuff...
1454 fps was your average...

Intercooler the Underwood 200XTP load you show as 8.8 grains

but in my testing 9.4 grains of 800X yielded 1250+, and I think someone else posted the same 9.4 grain from pull-down.

See Redlines post here; http://10mm-firearms.com/factory-10mm-ammo/finally-5-underwood-10mm-ammo-disections/

Yup! Did you see how close I got to Mr.Redbull on the Nosler 200's? Within 2 FPS average... we always did match up well even different places and Chronographs. I'm loving my setup on the Chrony with all the new parts and all. So happy with how everything shot today too!

No more doubts on the DT ammos.

DoubleTap 200 Nosler (Hunter): 1218, 1209. Average = 1213.5 FPS/ 654 LBS

Thanks for the two gun comparison on that load.  Average of 58 additional fps and 60 foot pounds.  Not bad.  I wonder what that load achieves from a 6" barrel.

The Hunter is a 6" barrel.

My bad.  I thought it was a 5.5" or something around there, but still under 6".  Good to know.

As mentioned elsewhere I'm curious as to the 10mm 200gr Nolser results (all of:  velocity, expansion, penetration depth, and tear down).

This very much. Gonna be interesting trying to get that 400 gr behemoth to stop in gel.

What ya got that shoots a 400gr? 


The 200's left out yesterday with a bunch of others. The Nosler and PowRBall will be interesting! In your opinion although we haven't done the Hex plated, PowRBall or Nosler what is looking like the best HP? Also in there is a couple of Winchester Silvertips although they have have been done to death.

Maybe he's gonna load up one 10mm round with two 200gr Noslers stuffed in it with 1 grain of 800-X and a Large Magnum Rifle primer?

Yeah sorry I meant 300 gr had fours stuck in the head from .44, I guess.

So far it looks like 165-180 gr bullets do best, in my inexpert opinion.

I knew you meant something else, just wasnt' sure what.  It happens to the best of us!

.44 bullet heavy. Go deep.
