Well, for at least part of your statement, it may be as good as it gets with weights up to about 150-154 grains. HOWEVER, after that point the velocity / pressure curve comes into play. Now, you can still shoot it with all weights, but you have to back off somewhat at the upper weight bullets, or pressures will occur early. But as far as a accurate and relatively non temp sensitive powder, 7828 is tough to beat.

To get top speed with 160-175 in 7stw's you should be at rl25-retumbo or slower.
Thanks, and will do. I'll probably glass bed the action to see if I can tighten it up. First, I'll try the slower powder.

shoot and shoot more.

I shoot mine enough to sight 'em in, knock the soot out and go for it. I'll think about cleaning if switching type of powder(single base/double base) or bullet composition(guilding metal/pure copper) but other than that i just don't let her get filthy.

Thanks for the input on the 7828,I have found the SSC gave me no trouble with the 160gr Sierra,and pressure @ 81grs.I to had signs with the straight 7828 also @ 81grs.I like this powder for the reasons temp stable and very accurate.........

Re: 7mm STW Brotherhood - For those who shoot the 7mm Shooting Times Westerner

Sorry guys,I listed my 140 load its 81grs. I got to thinking and went to my book where I should have gone,before spurting my mouth off.My 160 load is 78.5-79grs. depending on which of the three rifles I am shooting it in.I will never leave the stw,but I have to keep three batches of brass one for each rifle as I fire form and neck size for them.........Again sorry for the misprint........PD......you guy were probably thinking "this damn fool is going to blow something up...........
