Does a Remingtom WSM receiver (used for a custom 7wsm) need to have the feed ramp altered to feed 180 bergers out of an AICS mag?

TIA

Would you happen to have a picture of the modification? (I searched but found no love...)

Thanks.

You can do this in 1 minute and a dremel "cone shaped" grinding stone.
***You need to pop the plate out of the front of your AI mags first so your longest OAL rounds fit. Then insert the mag to see how much the action needs to be modded.*** (like wnroscoe said below)

If the front plate has been removed from inside the AI Mag I'd notch the feed ramp. I used a .250" center cut end mill to do mine using a plunge cut (.260 Rem, modified AI magazine) A dermal will also work but, be careful. The same holds true for any caliber that has had the front plate removed from the AI magazine.

Load your magazine and start it in the rifle, you'll see where the notch needs to be and how much you'll have to remove. Dont just start cutting.

That is EXACTLY what I needed to to know--thank you. The work will be done in a proper machine shop--I am not a fan of the dremel for metal work on rifles.

You'll be GTG then. I only made my notch about half the diameter of the .250" end mill, worked like a champ and the rifle feeds like a fat chick at a buffet (I stole that saying from 7mmRM)

I did mine with a dremel (AKA hand mill), it came out pretty nice!
