7mm rem mag. Hsm 168 berger

[Spedray]

I have been shooting this round for years. Picked up some more ammo recently and my groups went from .75 moa to barely keeping it one paper. Shots everywhere with no rhyme or reason. Tried some 175 power shoks because I thought my scope was bad, and they shot .75 moa. I noticed they have their own brass whereas the older stuff was norma. Also they are packed in a cardboard package of five instead of a plastic holder. Anybody else seeing this?

That has to be frustrating!

My guess would be that they are trying to deal with the shortages also and possibly using different components where they can find them.
Different brass, primer, powder cann all have an effect.

But to go from .75 to 8 moa at 100 is unreal. I bought 5 boxes and thought I was good for awhile. Next step is to clean the barrel good and shot over a chronograph to try and see that's going on.

Those exact rounds are what pushed me in to reloading. I purchased 2 boxes that shot great than 1 year later picked up 2 that shot horrible. Brass was different on the two lots. That was years ago before the shortage.
