My experience with that is 3 Parker Hales, VZ 34 and a 1953 marked 98.
My 2 Mark 10's already had good springs. Forgot my 9.3x62 (dont know what model) I put a heavy spring in it as well.NP just.lucky, sounds like.

Re-read my first response, sorry about that. On some meds. for my new knee and had a couple beer on top - My bad!
I don't get on the fight, but can be sarcastic. Again, sorry - you're right, was "off base/side".
