I find 1oz/1145fps to be a bit much in the recoil department for a 6lb 16ga....for target shooting, hunting low volume game it is fine.
1oz/1295fps seemed a bit overkill for trap loads in a 8lb plus 32" 2E Krupp Pigeon Special.
The above guns are hard buttplates.
To keep this in perspective, I had no problem with heavy bismuth loads in a Gold Light 10ga.
