Going to be working on some HW and Bismuth loads in the next few months, anyone wanting anything in particular please let me know.
I have thought about buying some Bismuth BB and loading up some 1 3/4oz for Geese. Remington hulls with TPS1035. If the cost of Bismuth shot go's down like some metal guys think it should. It would be a bit more cost effective.
Reasons for a 1 3/4oz 10ga BB Bismuth load. 2oz of Lead BB is right at 100 pellets. B .17" from ZIP metal is $109 per 7lb. http://www.zipmetals.com/ZipMetals-Bismuth-BBs-B-17--7-lbs-_p_242.html
Finding the pellet count for 94% Bismuth 6% tin in .17" B shot size might take buying 7lb. But it should be near 100 in 1 3/4oz.
This is for 3% Tin 97% Bismuth but it should give you a rough idea with 6% Tin
10GAGENUT, I'm interested in HW and Bismuth recipes. I've got both. The Heavyweight is HW15 in #7's. I'm looking at 'salting' existing steel shot and Hevi-Shot recipes with 3/8 ounce of HW and using felt and/or cork to make up the space difference. Tested loads like this would be good however, especially with current Alliant Steel powder. I have Lot 34 and lot 38 powder. Also wondering about PT53 12 gauge wads also salted, but there no existing data for a load that would just fill the cup with two types of shot. MY '10' is retired, but I would get the 10 gauge manual just to have it. Thanks, Bob
I've never had much luck with duplexing shot types I've tried HS and HW13 with steel and basically wasn't to impressed, I would think with HW15 and steel there may be to much weight difference to get a decent patterning load. Some people seem to have good results with these loads, if anything with HW15 7's I would try for a 7/8 or 1 oz load which you will get better overall results from, cost more but it may be worth it.
The B 6% tin Bismuth should give the 100 +- pellet counts I would be interested in. I would probably just weigh 100 then load using the primer tray. 100 pellets are plenty for where I would use this load. Should work unless the Bismuth maker is being honest on their quality control.
Rotometals B shot is not very consistent weight wise, I've spoken with several people that said weights were off by 2 grains from pellet to pellet. They should be able to get a bit closer than that.
