Dan Wesson Razorback doing great now!

[sqlbullet]

I ordered a FBFPS from Wilson for my Razorback... but have not put it in yet.  Had not thought about the mainspring.  Only about 1/4 of my loads are "full power" 10mm loads.  The rest are "FBI" loads.  Would the mainspring increase help in my situation?

A FBFPS + a 25 lbs mainspring will yield the same damage to a shok-buff in 25 rounds fired with no recoil spring as 45 acp 230 ball ammo does.  The is based on testing done by Ned Christensen of Michiguns.

I think this should be the factory set up for 10mm guns.  Clearly the factories don't agree with me for whatever reason.
