I understand about tuneing with the recoil spring, that I have thought about, tuneing the load on the other hand... . As I think about it, the load may need to be adjusted, assuming it is already close to the PF, 'up' to work with the new spring/springs?. I quess you may even have to change bullet type and or powders in a extreem case?.
I do have a rule book but after reading some of the dicusions about different rules i'm quite honestly alittle apprehensive about assuming it could be done without it being spelled out exactly.
As you can quess i'm new to the sport, only having shot a few matches this last summer and fall. None the less, i'm HOOKED! I love this sport. I was not at all confident with a pistol, except within personal defense range, untill I was dragged to a match and offered the oppertunity to watch, listen, learn and do. It has change my whole outlook on handguning. So much so that I deer hunted this year with a handgun, successfully too! Thanks for your help.
