Gentlemen,
After my conversation with JES he agreed to re-bore my re-bore to a .349 bore and also recut the throat. It seems he's had some problems with tight throats with his guns.
As mentioned his turn around time is good, the gun was returned to me on Monday. With the holidays and bow season coming to a close I have not had time to check anything and it may be a few weeks before I do but I will report back. At the least next week I'll try to slug the barrel again to see if it's really at .349.
In the interim yet another guy who had a .35 Whelen rebored by JES and had problems has stepped forward,, a Rem. 7600 blowing primers, the solution seems to have been recutting the throat.
