I am a novice trap shooter, sporting a vintage 870 Wingmaster pump.
Couple weeks ago, I shot 4 rounds using Federal 1 1/8oz target loads. Afterwards, felt as though my shoulder had been squarely kicked by a surly thoroughbred (one who just hated shotguns, no less).
This week, shot another 4 rounds using Score Silver 1 1/16oz target loads from ammosupply.ca. Afterwards, shoulder felt as though I had been nudged by a somewhat apologetic mule; much improved.
Next week, I look forward to shooting another 4 rounds, this time using Score Bronze 1oz target loads, again from ammosupply.ca; shoulder is hoping to be nuzzled by an amiable pony.
Kate, my shoulder thanks you (and Prairie Shot).
