Robert McLeanSo I picked up a box of SST 154 from a guy on the cheap. Just wouldn't shoot for him. Anyway I am just looking to do some load work with my H1000 in my 7mm rem mag sendero. The H1000 is all I have right now. I can't for the life of me find a min. and max. for that bullet. I've only got a winchester book and it doesn't list it. The strange thing I have noticed is this.H1000 140 gr. jacketed: 67-70 150 gr. jacketed: 65-68 160 gr. jacketed: 63-66 162 gr. jacketed: 67-70 I need a min and max for the 154 sst to start my work. Not looking for a load, just somewhere to start from. I was thinking 65 but I just though I would ask the question. And can someone explain to my how those min and max numbers make sense? I know its all about pressure but it just doesn't make sense to me. |

Paul LevermanRe: Hornady SST 154From what I understand, it has to do with things like bullet shape and bearing surface, as well as weight. Not saying that this is the case, but in your list the 140gr and the 162gr have the same numbers, so a guess would be that the 162 is probably a long for calibre, boat tail, with a short bearing surface. It may also be that the shape of the bullet allows for more "freebore", hence the ability to use more powder. This is all a guess, at best, but it's what seems to be the case.Hornady, vol. X, lists the 154gr SST, H1000, start at 61.2 (2600fps), max (red zone) at 68.3 (2900fps). 24" bbl, 1:9 twist. |
