I know there are easier ways to go about this, and I'm not trying to build a custom prize winning target rifle. Just something to play with, maybe a year from now change again.
Other than availability, what I'm most confused about is whether or not my 110 is a long or short action. Then what bolt head do I need. When I see a 223 head listed, whether in stock or not, it usually has a "SA" in description which I assume means short action. But then looking at specs may say fits 10 and 110.
I'm probably over-thinking this, just don't want to order wrong parts. It looks fairly easy to swap parts and adjust firing pin depth.
I'm old and retired so I got time to tinker.
