You can re-bore to 356Win or 35/30-30 without making any changes to the bolt. It's a straight re-bore and re-chamber. I have not done a Zane Grey, but did have an SC converted to 35/30-30. I was very happy with the results.Since they were all made in 30-30 you'd have to change or modify the bolt to switch to the .35. I recently had mine rebored to 38-55. Haven't shot it yet so can't report. I have a 336 rebored to same caliber however and it works great.
I mailed my complete Glenfield rifle in a hard plastic padded gun case, with a box around it. I paid JES an extra $25 dollars for the added shipping cost on his end. But I cleared it with Jesse first.I understand this in an older thread and that few may respond but must ask...having just acquired a Zane and thinking seriously of sending to JES doe 375 rebore. The ? Is it wise and easier to remover the wood...and bolt for JES to do work??? This rifle is decent and am sure the 375 change makes sense.
I hope you reload, or plan to soon. That will keep you shooting, no matter how little factory ammo is available. Best of luck!Hogan and ballistics, Thanks and sorry to hear, Hogan about...USPS....too much water in their system and no buckets.
Epoxy, carefully done, is wondrous...I had already decided to remove butt stock only...forearm r&r is so picky...will leave bolt in also...you watch I will change to 375 and 30-30 ammo will be abundant as it was.Must tend to snowblower now...
Thanks and all the best.
