I have been doing some testing on using the same brand of brass in my Rossi 92. 357 cal with Lyman mold 358 156. Only shooting 40 yards. Using 15.0 2400 . Shooting from a rest with red dot sight. Any way I was using mixed brass. Win,fed,PMC. I was amazed at the change in point of impact. All mv approx. 1456 fps. I would get maybe 3 in 1 1/4 inch with the win. The PMC went about 3 inches high. Fed shot left about 2 inch. Then went back to the win. Right back where it was before. I even cleaned the barrel and started over. Same as before. S it the brass or just a fluke? Should have tried this before instead of just using the random brass. I will be doing this again to see the difference,if there is again..
