Howdy was wondering if anyone who has been reloading a good while would know the answer. I wanted to start reloading Winchester AA 2 3/4 for trap and had a question about powders. I am reloading 12g with WAA 12 wads, 1 1/8 oz. #8 shot, CCI 209M primers, and I wanted to start using Alliant e3 powder for around 1200 fps. I seen they have recipe for Red Dot but only place around here that sells it was sold out and guy told me to use e3 and to back off the grains a bit. Their book has the recipe with Red Dot at 18.5 grains for 1300fps. I was wondering how many grains would be sufficient of e3 to get close to 1200 fps as possible. I tried calling Alliant 4 times and keep getting answering machine for there customer rep and sent 3 emails and got no response. Thank you for any help is appreciated.
