There are two basic performance parameters I’ll be concentrating on to evaluate the loads on their effectiveness. One is sufficient pattern density -- enough pellets in the pattern, at a given range, to ensure multiple hits on the target’s vital areas. For turkeys, the load will have to place a minimum of 210-230 pellets in a 30-inch diameter pattern with three to four skull and/or cervical vertebrae (S/CV) hits on a turkey head-and-neck target to be deemed effective. The other is ample pellet energy -- enough per-pellet energy to reliably penetrate the target’s vital areas at a given range. To ensure the pellets retain ample per-pellet turkey-S/CV-penetrating energy the pellets must not be used beyond their maximum effective ranges. My analysis of the maximum effective ranges for pellets comprised of different metal types is:
35 yards -- No. 6 lead shot;
45 yards -- No. 6 tungsten-composite shot (min. 12 g/cc), No. 5 lead shot or No. 4 steel shot;
55 yards -- No. 5 tungsten-composite shot (min. 12 g/cc), No. 4 lead shot or No. 3 steel shot.
Some may say that these maximum effective ranges are too stringent, but as previously mentioned, turkeys are big tough birds so let’s error on the safe side when it comes to pellet energy.
I read your excerpt Dewey and I don't buy what the guy is saying.
First off I think his patterns are too thin. He states 210 to 230 hits in a 30 inch circle. 100 hits in a 10 inch circle is a common accepted min kill density for turkey. That's 100 hits in an area that is about 78 sq inches. More than 1 hit per sq inch. A 30 inch circle has 706 sq inches. 220 hits is less than 1 hit every 2 sq inches. A little too thin for my taste and NOT "on the safe side". IMO 220 hits in a 30 inch circle is just too thin of a pattern to consistently kill turkeys.
As for his stance on pellet energy, now I think he is too much "on the safe side". There is being on the safe side and then there is being realistic. Lead 6's in my experience, and many others, will kill turkeys out to 50 yards IF
you have the proper pattern density. I believe I am being conservative when I shoot lead 6's at 40 yards with a 5 yard cushion and a proper pattern density.
I came across this post this morning on another forum. It talks about lead 6's and their lethality. There is a little BS in there, but I think you can see that others have had good experience killing turkeys with lead 6's at reasonable ranges. http://gobblernation.com/phpBB3/viewtop ... df41edf838
