I bought a can of Hodgdon benchmark and loaded some 22-250's and man it was great good groups and metered great it looks like varget cut in half. well it's a fast burn rate and worked well with 50grn bullets so I thought I would try it in my 243win with nosler 55grn BT's but I could not find any data so I bought Hodgdons annual manual for 2007 and it said start at 39grains so I did and the first round sounded like a 300 wsm going off and I had trouble lifting the bolt flat primer and shinny skid mark on 30% of the rim all the signs of a hot load. Well I called Hodgdon and the guy said it's the right data and could care less. I then looked back in the manual and for a 58grn hornady bt it shows start with 35grains?????? can I just start over and start at 35grains with the 55's Now keep in mind my gun has never minded warm loads at all. I think the guy at hodgdon should have been a little more concerned dont you?
