Hey guys, I am not seasoned in my reloading and I have a question. I am trying to load barnes tsx 270's in my .375 HH. I went through what powder I had and I found data on IMR-4350 which I have 4 lbs of. So i went to load some. The starting load was 74.5 and the max I believe was around 77.5. When I threw 74 gr into a case it looked to be just below the start of the shoulder. The bullet would be compressing the powder at the starting load. If anyone has any experience using this powder for this caliber please help me out! should I be afraid to compress the load slightly? What is safe? can anyone give me some recipes for .375HH using IMR-4350? thanks!
