SMOKELESS 20 gauge 2 1/2" low pressure
 

Now last but not least I am also working with a 20 gauge 2 1/2" chamber gun that I will need some help with powder's and charges .

Will be using Remington Premier hulls trimmed to 2 1/2" , will either load 3/4 or 7/8 ounces of shot .

Primers used will be like the others ,
CCI209 and WIN209

Wads will be the Clay Buster 1078 and 1075 .

Thanks !

I asked for data for 2 1/2" . All they show is 2 3/4" . I am sure something has to change when one cuts a 1/4" off the shell .

And on top of that I already have data for 2 3/4" shells from Hogdon , IMR , Winchester and Alliant .
