I'm putting together my 1st 303 rounds today. I've got hornady 174gr fmj as I'd like to stick with 175grainers. I'm using 2208 today but I do also have 2206h and 2209.
Which powder do you blokes tend to lean towards?
Looking at the data I felt like 2209 looked a bit inefficient compaired to 08 and 06h.
A mate gave me 40 once fired S&B brass. All of them were around 10thou longer than the max length after full length sizing, is that common for 303? I know people tend to not like S&B brass, but free is good
I must admit I've always thought of 303 as a large case, so I was really surprised to see how much 38gr of 08 filled the case when I filled one for the 1st time.
