Have owned at least 4 different 110s over the years. I'm left handed. A couple I didn't own very long, but the other 2 have both had this same problem at times.
Because of the upcoming Bison hunt, I had to get out my old 110 in 30-06. Hoping to use the same ammo in it and the kids 7400 in 30-06 as well. Last week at the range, the 110 would not fire some of the Rem core lokt 220 rounds I put in it. Some it did fire. I have adjusted the pin before, tho maybe not on this gun. This one worked fine a few years ago. Haven't used it much as I like the savage 11 I have in 300 wsm better.
Anyway, adjusted the pin to protude a tad farther. Today at the range, with handloads, none would fire. I successfully fired those that did not fire in the 110 in the 7400.
I'm at a loss. I think the spring tension and the pin protrusion can both be adjusted but am not sure what to do since my last adjustment apparently made things WORSE!!
Here is a pic of the disassembled pin:
Anyone got any suggestions?
