Steel Shotshell Data... Am I missing something..?
Hello, I am new to this forum. I have a question about steel shot data.
I have been reloading shotshells for a while now, but have always just done 2 3/4" lead shells. Since I am a waterfowl hunter, I decided to reload some 3" steel this year. I have a reloading handbook (Lymans 5th edition to be exact) I started reloading these, and they patterned very well: Winchester Plastic Cases with Plastic Basewad. 43 grains of Alliant Steel power Fed 209 primer One BPI Ranger Plus wad One 20 GA 1/4" fiber under shot This shot was 1795 FPS with 10500 PSI And then, I got looking at another load that had more pellets...... Winchester Plastic Cases with Plastic Basewad. 36 grains of Alliant Steel power Win 209 primer One BPI Ranger Plus wad This shot was 1480 FPS with 10800 PSI Sooo... My question is, why can't I just load the exact loads I am currently doing, except take the basewad out and put in 1 1/8 ounce of shot. (basically, why can't put 43 grs of powder in the second loads to get more FPS?)? Also, there are many loads that have all the same components, except the have a car over the shot. Do I actually need the card? I know these may be STUPID questions, but in my time of reloading, they all were light lead loads and never had to deal with high pressures and such. Thanks very much for your help! |

If you increase the amount of shot weight, pressure goes up if using the same powder charge. More shot lesss velocity. You did not post the weight/amount of shot in each load you listed.

Shotgun recipes are to be followed exactly. Any change in components can raise pressure dangerously. The card over shot could be to open the pattern more on firing, this is a guess. You might want to post here for better answers. http://www.shotgunworld.com
