The short of it
1)Bought a Glock 20
2)bought a Lone wolf 40 S&W conversion barrel.
3)Ran a 40 S&W case through my press (setup for 10mm). So basically I have a 40 S&W loaded to an OAL of 1.26"
4) 40S&W loaded to 1.26" drops in the chamber and as far as I can tell, does not touch the rifling.
I determined this by
A)noting that the round chambers freely and does not get stuck (can't wedge it into the rifling). Feels like it's spacing of the mouth of the case.
B) Jammed a bullet into the rifling measured to the crown. I did this for three different bullets and got 4.148", 4.144" and 4.144". I then put the 40 S&W loaded to 1.26" in to chamber and measured to the bullet and got 4.182".
SO by my calculations the bullet is seated ~0.035" away from the lands.
Looking at the chamber, it does look to have a long throat.
So what I am asking is does anybody see an issue with doing this?
My intent is load 40 S&W up to 10mm velocity and just simply use 40 brass rather than 10mm.
Just wondering if I am missing something before I go to the range tomorrow. Starting with 40 S&W data.
Thanks,
Andrew
