This is my first time reloading, and I've consulted lots of different sources for min and max loads for a 150g bullet under IMR 4350. But they all seem somewhat different, so I wanted to get an quick poll as to what were optimal and max loads for people reloading a 150g using IMR 4350 in a bolt gun.
This is what I've accumulated from "official" sources:
Lyman (49th ed): Hornady 150g SP - 49min 57max
Hodgdon/IMR Site: Nosler Ballistic Tip 150g - 54min 58max
Hornady: Hornady SST or GMX - 50.4min 59.9max
I'll be reloading a Hornady 150g FMJ BT and trying to find a "matching" load for Hornady SST & GMX (supposedly the same ballistically) for hunting. Don't worry. I plan on doing this separately, but I'll probably use the FMJ BT load to help zero in on a good SST/GMX load. (Their BCs are very, very close.) I'll be using WLR primers if that makes a difference.
Anyway, your own pet load data would be a great help as well as any max data. I don't have a chronometer, so I'll only be looking for pressure signs. Right now I'm thinking of starting at 54g and going to 58g with the last two grains in 0.3 increments. I'm not planning on going for really hot loads, as I'd like my brass to last longer.
P.S. Was at the range today, and managed to shoot a 1" group with factory ammo, so hopefully a good load will help that.
