I understand that FPS doesnt mean anything when it comes to Pressures.
I would imagine that 1300fps is quite a bit higher in pressure than 1150 or 1180 though.. and im not going to shoot 1300 in my sxs..
I dont reload so thats probably more the problem than anything as it seems that if you reload, there are formulas that will take into consideration the Pressure you are getting from certain loads.
Going the easy route, i was just trying to find out the pressures of some of the Winchester AA's extra lite target loads that are 1oz 8's at 1125 and 1185 fps..
Probably not going to be able to get that information anywhere.
I think that we have determined that those loads should not harm the shotgun since i do have the steel barrels and not damascus. So I will try those and see how it goes, and how they feel, compared to the RST 2 1/2" (1180) lite loads i have been using but are getting expensive with shipping etc..
Thanks for the input and what ever else anyone wants to add is very helpful information and speeds along the learning process, as i really dont want cracked wood and bulging barrels if i can help it
