Or... Underwood 9, 10... whatever they are calling it ;)
Good work!
Is this the same powder ? Clean shot ?

No it would be this one MAJOR PISTOL = D037-01
See the Shooter's World Guide for reference of the cross overs

Now the hard question !
Where can I get it ? Found several vendors such as Powder Valley etc...but none have a listing for the Major Pistol ? Or maybe I'm missing it in the ads ?

Why bother?
Use the longshot data: http://10mm-firearms.com/factory-10mm-ammo-pull-downs/underwood-135gr-sierra-jhp-pull-down/
I haven't looked at the Sierra vs Nosler JHP's up close, but reduce 10% and work up. Way less powder using Longshot, and very, very similar performance.
Power Pistol will get you close with even less powder. Alliant's max load is listed at 10.6 grains at 1.250" for 1530 fps, probably closer to 1500 from a Witness in real life.
Parabellum Research loaded 11.6 grains of power pistol at 1.256" and it was tested by IC at 1541 fps. Pull down write up at http://10mm-firearms.com/factory-10mm-ammo-pull-downs/parabellum-research-pbr-135gr-nosler-jhp-v-supreme-pull-down/msg34244/#msg34244
LOVEX is an Imported Power and Not sure but Powder Valley Inc. doesn't have the MAJOR PISTOL which equates to D037-01.
According to LOVEX it is *(Very similar to AA#7 by weight)
Shooters World only sells to those with a FFL6 unless things changed...
I wish I could be of more help but it is what it is
you guys are helping !
I had a G20 gen4 I couldn't get used to shooting as I favor the 1911 style. Bought an STI perfect 10 that is accurate as hell with the Underwood ammo ...but they went up about $10 per 50 and I've already got a Dillon press so figured if I could come close to duplicating their formula I'd try and roll my own ?
There are plenty of different Underwood loadings listed when they first started they were using IMR800X, then went to Longshot as he changed to other loading machines because those didn't handle the 800X well. Since the powder shortages he has ventured to this LOVEX stuff which may be cheaper and available!
Be sure you look over the Double Tap and SwampFox pull-downs and compare them to Underwood...
I get some of my best accuracy using Blue Dot
Mmmmmm....Blue Dot.
Near max velocities with max accuracy. Love that stuff.
