2F is decidedly more coarse than 3F, but should I use less 2F than 3F?
specifically I am experimenting with black powder in .45 Colt.

Yep  RIP I loved the Surfin' Sound

Got the first one posted

The Wilsons, Brian, Carl and Dennis sure had their demons.

Good Vibrations was my favorite tune when I was in high school. R.I.P. 

Brian Wilson has passed at 82. 
  I grew up with their sound, many Good Vibrations.

I have an EPS blackpowder belt that is 2-1/2" wide with 1-1/2" billets.  It is 43" to the center hole.

I can take some measurements for you off it if you want.

I was looking advise for a technique to get the size correct. I know they are 2.25" wide with 1.50" billets. And I need it to be 41" to center hole.

The only police supply store in my area went out of business years ago and sold out to Galls. All the PD's now order from the internet as far as I know.

Here, in my end of the swamp, an Apple Pie, that is Honey Crisp Apple Pie is 18 bucks.  And it's the bestest durn Apple Pie onna PLANET!!

When last visiting the Conch Republic, a slice of apple pie was $4.50 and I be betting it's even higher now.  And, that was was for jam-n-fudge run-of-the-mill apple pie.

Might be a good idea to visit a Police Supply dealer and take a good look at one - include photos and measurements so you understand their manufacture.

Scouts Out!
