I am building off a Rock Island Arsenel 1903. Its ser.no. is 318,668, the recomended cut of is 286,506 for the Rock River Arsenel. Thanks for the tip about Kinks, I am skimming th ones I have now. I do agree about the cross pins. I am planning ahead in the event I screw somthing up on inleting.

I cecked the unalterd feed ramp with .300 win. Mag. dummies ad a dummie shank/chamber. At the moment it almost cycles the same way with 30-06 and the mag. well holds 3. Looks like the feed ramp needs to be moved back a little bit, due to it shaving a bit of the bullet tip.
