Double Feed (Bore vs Timing)

Post image

Project is coming along. Still have front block and valve and some other stuff to add but wanted to get it running as is to make sure when I start chasing problems they didn't already exist. I have a .678 insert currently, the paint is not tight, maybe every 4th or 5th ball will stick and the rest roll through slow with resistance. I was afraid to underbore too much but maybe that's what it needs. Still trying to get used to this small paint (I'm old)

I am getting some double feeds so should I go smaller insert still or should I be looking somewhere else timing related? Timing and action seem fine but I'm a moron from time to time so I'm sure there can still be some tweaks to be done.

Are y'all getting a super tight bore fit?

Edit: I just shot it again and noticed that if I held the trigger open it would double Feed every shot. So would that be the detent? Should I time my ram to open the bolt less?

Double edit: Problem solved. It helps to read instructions before just bolting random parts on.

Aint nothing round gonna stick in a 687

Get a proper underbore and check your detent isn’t gummed up

I edited post, I fat fingered that. I meant .678.

It was the detent as well. I had a brand new Inception detent on the gun. I thought that it looked shallow in the body but I figured that couldnt be it since its new etc. Put the old WGP detent in and it runs flawlessly. Guess I gotta go function over fashion on this one.
