Good morning everyone,
I'm still fighting with my K-31 Swiss, just a little. I am actually getting pretty good accuracy, with the RCBS 30-165 SIL mold that I bought a few months ago. With 16.5 of 2400, I can usually keep 5 shots at or around 1.5 inches at 100 yards, with a 3 x 9 scope. Most of the time, I have a couple touching, and the a couple out a little bit, but over all I am pretty happy.
The struggle continues to be the hard seating into the chamber. I guess I was blessed with or cursed, depending on your perception, with a gun with little to no throat erosion.
Every bullet that I have tried is difficult to seat into the chamber. My k-11 closes on this same bullet really easy, and I am hoping to get the k31 to work the same.
The RCBS is the best so far, but when seated to the correct depth, I am engraving the rifling into the nose 2 - 3 thousands. If i seat down about .100 it goes in way better, but my accuracy suffers some.
I feel bad for slamming the bolt shut to close, and I fear that this will eventually have consequences.
Any ideas? I know there are methods of nose sizing, but I dont know how that works.. Can some one explain that process to me. Sorry to be ignorant of this procedure..
Also, I could borrow an old Lyman .309- 334 mold, from a guy. Has not been used in many years, but looks like it would work. I hate to borrow anything, but the bullet profile looks a lot like my 30-165 and I wonder if the nose might be smaller? Do any or you guys have any knowledge of this bullet?
I think this is an obsolete mold design, and I had not heard of it, until he showed it to me.
Any thoughts would be appreciated..
