@wind gypsy It's supposed to be a 0.003" neck tension mandrel, when you order from KM you order by desired neck tension and not the diameter of the mandrel (in this case it is 0.2415"). Which I know doesn't make sense, as spring back will differ between brass lots and brands. However, I think...
Always a soft spot in my heart for the Ruger No1. A friend has a 30-06AI in a No.1 that he is holding onto for me for when I have the spare cash. However, my itch is for a break action at the moment.
As said above, I found using a custom undersized mandrel in conjunction with FL sizing for minimal shoulder bump to be the single biggest improvement in my ES numbers over any other change in my reloading process.
I hadn't heard of them before, just had a look at what they retail for in Australia 😬 I could build three custom rifles for that price point. It looks like the perfect single shot though!
That's a good consideration I didn't think of, having the option to switch barrels would provide a lot of versatility. I also like the idea of being able to improve the trigger.
I am located in Australia, and typically not many hunters would use a single shot rifle for deer hunting. Generally, if you come across one its a 45-70 H&R. However, I have an itch I want to scratch, and that is to hunt with a single shot break action rifle.
If you had to choose one to start...
