Yes Retired Firefighter, cut my teeth on A tiller,
The_Shadow, Thank you for the info
I planned on starting a few loads with 231 At starting weights, along w/BE86
I've got approximately 2 lbs of 231 left if I can find a good powder for both 45acp and the 10mm then I'd order up a bunch I guess I Just need to read and study some more.
  1911 junkie here with an occasional Glock thrown in.  I've jumped in to the deep end of the pool now when it comes to the 10mm

Newbie here, New to reloading the 10mm but not to reloading in general
Picked up my secound 10mm pistol yesterday a 30 year old Delta, & DW Razorback
I've got dies, cases, New Starline, once fired Master, and Winchester on hand. Lg assortment of LPP
Both standard and magnum. With powders of 231 my favorite for 45acp, power pistol,Be86, & Unique
Bullets on hand 180 GDHP, and 180 Hornady XTPs.
With 180 tmj Armscor on the way. 

I'm seeking to load light loads to start thought to try my hand at using 231 initially and work up

I was looking at the .40 loads for the Speer 155 tmj s would those loads be reasonable to approach on the high side in/using 10 mm cases and the 1.250 col with LPP, ? 
Any suggestions for milder accurate 10 loads would be great?
Planning on picking up a Lb of blue dot also. 

Trying to Put together a supply of reloading components local ranges require jacketed bullets mostly

My SD loads are factory win Silvertips 175gr and Corbon 165s

Congrats, Valors are sweet
