RE: How much powder do you use?
Same here, the hotest accurate load I've found in any of my guns is 130gr of Pyro pellets under a 300SST. Everything else is around 90 to 100gr of loose 777 2f in the inline and 70 to 100gr of Pyro P in the sidelocks. I too look for the most accurate load for each bullet I shoot, not the fastest.
