Morning ya'll, for the second time I have broken the spring(s) in my jewell trigger in my 243 Surgeon Scapel. My load is 42.5 H4350, Br2 primers, lapua brass and OAL of 2.840. Velocity is 3000fps. I get no pressure signs until the primer is pierced and the resulting spring damage. This has occurred over the course of firing 600 rounds in total. Any help would be appreciated.
