Thread: YALDIZ SINGLE SHOT .410 - LIFESTYLE BLOCK

A forum quote I found recently 3in vs 2 1/2 in shells

"In terms of pattern percentage, I'm sure that the 2.5 inch shell does a better job than the 3 inch shell. The very long shot column of the 2.5 inch shell is even longer with the 3 inch shell (meaning more deformation of the lower tiers of shot due to setback forces), and neither has a proper wad, just a shot cup. In addition, many of the shot cups in the 3 inch shells don't protect the entire length of the shot column, leaving the top portion of the shot column more vulnerable to bore scrub. Thus, with the 3 inch shell, there is more chance for shot deformation and fliers. But.....with a 2.5 inch shell, you have a 1/2 oz of shot, while the 3 inch shells have 11/16 oz or 38% more shot. I think you would probably still retain more shot in the effective pattern area with the 3 inch shell than you would with the 2.5 inch shell. Neither loading, in my opinion is good for more than about 30 to 35 yds. I've hunted doves and game farm pheasants with 410's and it is a great deal of fun as long as you respect its limitations.
I would suggest that you buy one box each of 2.5" and 3" shells, then shoot some patterns (on a large sheet of paper or cardboard) at 25 yds and judge for yourself!"
