Bolt o-ring, is it important?

I got some different o-rings to play with. I was trying to find a good match that wouldn't pull out my freak inserts. It has occurred to me is it even needed. People take o-rings of Autococker bolts all the time. I imagine there may be a small drop in efficiency and maybe consistency. Has anyone tried this? It seams like I heard of someone running a Phantom that way.

I would just put whatever size on that doesn't stick in you smallest barrel or insert. You can hurt efficiency by having air go back into the body.

This is correct... you don't need the oring, but it acts to seal the breech and ensure all of the pressure is on the ball and not escaping around the bolt. You will loose efficiency and will likely see more velocity fluctuation from shot to shot. I'll second what worrpt says, just use the smallest oring that will seal the breech w/o pulling out the insert - usually a 110 to 112 (you might have to stretch a 110 or 111), or a similar ID 1.5mm CS oring.

Could make you gun fire at the end of the pump stroke.Depends on the sear tolerance. Slide trigger adjust forward .Swing trigger slightly grinding the seer maybe needed.Food for thought.

I put on a big fat oring, it bumps up to the barrel and doesn't pull out my freak inserts. I'm getting 45+ shots on my buzzard

Great point! Sear tolerance definitely should be considered... unwanted autotriggering is always a possibility if you remove the bolt oring

True, fortunately mine seems to be one of the more forgiving Buzzards. It even works with a couple of my cocker barrels.

For sure the correct barrel is a must.
I always had great luck with deadly wind. The inserts never came out of those. I would then match the oring to the insert.
But lucky duck hit the nail right on the head.
Palmers will make you a nice barrel with a bevel. Ask for wedgits too. You have other options like the techfit.
Edit: and here

THE-SHOOTIST Anyone chubbin' like me for this?
mailmanmike Since Monday! That's more than 4 hours though, so according to those cialis ads I should see my doctor.
tlane77 I think for a non-chemical chubby it's 6 hours before its time to see a doctor. So you should be good for another couple hours.
splattttttt I wasn't goin to google "chubbin" because I assumed it had to do with fat. The lard type, not the fun stuff. But what ever feelings Jeff's experiencing, then they must be of the fun like stuff...

Figured I'd add to this, that SSC will also add a bevel to any barrel if you ask him; he did one for me a while back when I sent him a barrel to freak bore.
