Default Range report/powder consistency.

I spent a nice day at the range on Tuesday and got a few things accomplished. I spent most of the day shooting my muzzleloaders while waiting for my 7mm too cool between groups. It was a nice day, not too cool, not too hot, only a little wind toward the end of the day.

I had bought a new canister of IMR 7828 for my 7mm Rem Mag and loaded up 5 loads around my previous batch of powders accurate load to check and see if anything was different about the new batch of powder. I am using 140gr Nosler Balistic Tips. With the previous batch (bought about 2 or 3years ago) I was getting solid .5" groups with the best load and it spread slightly either side of this load. I'm happy to say that the new batch of powder did almost exactly the same as the old powder with one small exception, the oldpowder shot .5", the new powder shot .375". .5 grain either side ofthis shot about .75". All 5 loads grouped within about 1.5" of each other and the worst group was still under 2". I also had 1 round left over from the old powder, it printed within a half inch of the new powders group.

I didn't have a chony on hand to verify the velocities but the groups were so close to the ones from when I worked up the load the first time that I have to assume they are similar to the original results. IMR 7828 sure seems to be a consistent powder and has given me no reason to doubt it's reliabilityor accuracy.

I think I'm ready to hunt.
