I've heard good things about the Hornady SST bullet, so the last time I ordered from Midway, I took the opportunity to buy some SST bullets. These are the 150 grain .30 caliber bullets. I loaded them for the .30-06 with surplus 4895 powder.
IMR 4895 powder was originally a miliary powder for the .30-06 cartridge. While a lot of shooters say that there are better powders, this stuff came in my door as surplus powder, at a substantial cost savings. Of course, since the powder is an unknown variable in this rifle, I started the charges on the low side.
That is 25 cartridges with 5 of each load, and they go up in one grain increments, so I have five at X grains of surplus 4895, five at X+1 grains of 4895, five at X+2 grains of 4895 and so on. I mark the individual cartridges with a felt marker, either on the primer or on the bullet with a specific color, then put a cheat sheet in the box, so when I get to the range I'll know what cartridge holds which charge. When I shoot the targets, I'll transfer chrony data onto the target, then analyze that data when I get home.
Of course, while I'm firing, I'll shoot the lowest charges first and watch the primer for signs of pressure. If, for example, the X+3 load is showing pressure signs, I'll stop shooting. When I get home I'll disassemble the unfired cartridges and separate the components. There is no sense shooting something that might be unsafe.
I hope to find a load that will be sufficiently accurate that I can quit load developement and settle on a load for this rifle. The .30-06 has a reputation of being easy to load for. I'm betting that my primer/powder/bullet combination will yeild a good round.
