I posted this in the reloading forum, but may be a better fit here.

I am going to try to load for a friend's Encore in 22-250. I load for a couple of bolt 22-250's now, but here's my question.. how do I find the lands on an Encore? For my bolt guns, I seat the bullets long and run the cartride through the action pushing the bullet into the casing. I repeat until I know that I am at the lands, then I seat the bullet from there to desired distance off the lands. How do I do this with an break-over? I have a few ideas, but wanted to find out the right way.

Have you tried the Stoney Point Chamber-All tool?

The guage is probably the most accurate way, but here is how I did it with my 30 Herritt.
I took a fire formed case trimmed as exactly as I could to the trim length in the mannual. I then seated a bullet out way too far and pushed it into the chamber. ( Not forced, just thumb pressure.) I got an idea of how far I needed to go and ran the cart. (devoid of powder and primer) into the seater and pushed it in until I could almost close the breech. I then smoked the bullet and seated the bullet a little each time until the markings left by the lands was very faint. This was then kept as a guage cartridge for that bullet and others with the same ogive. I seat my bullets 5 to 10 thousandths deeper than that guage when working up a load.
Tedious? Yes, but I don't consider any time spent at my loading bench as wasted!
