He has accufit stock in long action. according to his post. My question about the recoil lug was to make sure his action is sitting right in the stock first. The he'll have to overcome the bolt throw then the mag issue. Just my take on it.
I did this with a 22-250 blind 30-06 mag several years ago.It worked okay but my solution was kinda rigged up and I went a more conventional route with the Axis 22-250 mag and follower,bottom removed. that got it done for me.
I believe that if he has the regular recoil lug it will not fit correctly from the start.correct? he doesn't say what his original stock setup is,was.
his deal is doable. I'm just trying to break it down in steps for him cause it's a little overwhelming when your new to this and new hear.Thanks for the pics Dave, a big help.

Lol I got so frustrated with it all that my last build was a new short action with the AICS bottom metal and an accustock from NSS. That took all the fun out of it!!!!
I was done in a 1/2 hour!
