20 BR feeding issue

I have just had a Rem 700 rebarrelled from 708 to 20 BR, it doesn't feed from the mag. When the rim of the case being pushed makes it to the shoulder of the case below it, it jumps out loose and is "flicked" into an awkward position. I have shortened the mag by blocking the rear but that has had no effect on this problem. I wonder would a HS Precision detachable mag be a better solution, has anyone got any experience with this?

Re: 20 BR feeding issue

The BR familiy of cases were designed as bench rest rounds where cartidges are single loaded. You may have better luck feeding from a mag designed to feed the .22-250. The Dashers seem to 'fit' better in those, don't know about the BRs which are a bit shorter.

All of the short fat cases are problematic as far as feeding, and the rails are difficult to
adjust perfect.

What I recommend on and short fat case is to find a center feed mag and have it installed.
the center feed mags hold the round instead of the rails on the action and can be adjusted to
feed perfectly buy simply bending the top of the mag in or out.

The other plus to the center feed, is less chance of bullet tip damage because it feeds straight
into the chamber.

All of my WSMs and WSSMs have center feed mags and I have no issues with feeding.

Re: 20 BR feeding issue

Thanks for the info, you have both given me some food for thought. I will probably try a 22-250 center feed detachable mag, but at around $300 it may have to go on the back burner for a while (the other half just doesn't understand).

Re: 20 BR feeding issue

I ended up staying with the factory bottom metal and just tinkered with it until I got it working.
I spent many hours watching what happened as I closed the bolt and then I'd pull it apart and bend the mag box a little, put it together and repeat the process again. It isn't flawless, but works 90% of the time ( it only fails at the worst moments!).

Re: 20 BR feeding issue

Yea I really want to build that but I have heard of feeding issues so I'm contemplating a 20-250.

thanks
