I have the lathe(and steady rest). I fit and chambered the barrel and I have the reamer and head space gauges. Oh, I also have a barrel vise and receiver wrench. It will only cost time and I will be tinkering with something anyway.

I'll try a different batch of primers before I do anything. I can use this batch for cast bullet loads where they should be fine. I just wanted to know how much I can take off the bolt face of a push feed Model 70 without creating another problem? Incidentally I also have the Tubb firing pin so I can easily adjust firing pin protrusion if necessary.

Thanks for the answers.
