Did you do a plunk test with the new barrel?Originally Posted by 4jorgies
Hello, I have a Glock 40 MOS in 10MM.
Right after o picked it up I installed a Lonewolf barrel, stainless steel guide rod and a 22# recoil spring. The guns intended use is woods carry using 220 grain hard cast bullets shoving them at 1250fps
While working up the load I experienced a squib. There was no damage because o caught it, dropped the mag and removed the round that chambered right after the squib.
Removing the squib took a lot of effort but I was able to get it out of the barrel without damaging the bullet or barrel. I had been thinking about slugging my barrel and thought I had just got lucky enough to have done that.
The bullet actually measures .394 after removing it from the barrel.
While working up the load my biggest issue was failure to feed and sever pressure issues in the range of the powder charge that someone else used to get to the desired velocity with the same bullet.
I only achieved the desired results when I removed the decapping in from my sizing die and ran the finished rounds throug it.
I have found that doing this is resizing the bullet to .396 from .401 leaving a very small portion of the bullet at .401.
I have a couple of directions I'm thinking about going.
1) remove the aftermarket barrel and use the stock one that came with it.
2) see if I can get custom sized bullets for it. Or resize them myself but this requires a significant investment in tools and time.
3) start casting my own. Same issue as above
4) continue my process as is but I'm not sure this is a good idea
Thoughts???
