In 1-ounce I presume ?I have loaded some Rem STS with 18.5 grains of Vectan Prima V, TGT12 wad and Cheditte primer for a trial run.
In what hull, and what shot payload ? If in a taper'd hull (such as a Remington hull), 21.5 grains would be way-way too much (for any payload).My first load was the 21.5 grains as shown in the chart. It seems very fast (no chrono) and a little too much for a one ounce load.
Yeah, - no lie....One of the continual complaints about trap shooting with a semiautomatic is the need to clean the gun often and clean it well. I shoot a competition synthetic and while some powders allowed me to clean less frequently the need was still there after 250 to 300 rounds. The use of the Vectan powder has allowed me to go to twice that number with no real need to clean then. Perhaps those shooters that have recoil issues will now be able to utilize a semiautomatic and Vectan powder to increase their shooting pleasure........ Larry
