I recently got into swapping barrels on 110s, and just found this forum.
I pulled off a .30-06 barrel & put on an ebay .243 which shot just fine.
Then I bought another 110, .270, pulled that barrel off, put the .243 on it and put an E R Shaw .35 Whellen on the first one.
My name is John I am 83 years aged, I live North of the Twin Cities Mn. I shoot at the Dell-Tone Luth range 2 or 3 times a week. I promise to be quiet.
