Hi Ya'll it's been awhile since I posted here but I have two questions about my 110... I am going to switch out barrels on my long action. What is the difference between a small shank and a large shank? When I pop the barrel off will I be able to tell by a measurement? Then it is an older 110 so will I be able to put an accu trigger on it or should I go with an after market trigger like a Timney?

Thanks
