243 AI feeding issues

Been having issues with feeding from a Remington 700 SA ADL.

New internal mag (WSM/SAUM)? Or new follower, same?

In my experience most feed ramps on production actions need modified to work with the 40* Ackley shoulder.

modified how?

modified how?

I do it by hand with a Foredom tool,
I make the ramp slightly lower and wider. When feeding from an internal magazine, staggered feed, you need to take down the sharp edges on the left and right of ramp that come off the raceway. Those edges will catch the wide shoulder and deflect the cartridge our of line with the chamber mouth.
You may have better results with an inline feed from a single stack mag, but the magazine may need modified for an Ackley as well. I have worked over several feed ramps for Ackley cartridges to feed from internal magazines, so it can be done repeatedly.

you opened the taper on the actual action to accommodate the fatter case at the front, that it?

Yes, it also improves feeding with a variety of cartridges, Creedmoor, GT, and PRCs. Several aftermarket actions like, Zermatt, Curtis and Terminus do not need this type of work. I have only done it on R700, Mod 70s and Ruger 77s.

How much to make that mod for me?
