For what you have said I would not get the big recoil lug.
I think a "proper" bedding job will be of much more importance than the big recoil lug..
Steve ( Mechanical Accuracy) can bed it for you or you can do it yourself.
Its not that hard and there are lots of guys here and on other sights that will be gald to help. Myself included.
I would not worry to much about the long action it should work fine, and depending on the chamber and twist it might let you seat the bullets out longer..
Good luck and let us know how it works out...
Will do. I'm going to give bedding it myself a shot...I'm a DIY'er whenever possible. ETA: Where's a good site with bedding info / directions? I've found some but they seem kind of amateurish.
This rifle was the inspiration, except the colors are gonna be different...
