Having grouping problems

Hmmmm, looks like I've got some cred now.

Try coming down just a tiny bit on that benchmark for experimental purposes, but I think you're doing considerably better than before, because my benchmark loads shoot well year round.

Your gun won't throw the first shot with benchmark unless there's a problem with the rifle.

I don't use Remington primers, but isn't the 7 1/2 a magnum? Try some BR primers, and your groups will probably be just as good or better than mine.

You get a lot of credit. This is my first time using Benchmark. I actually had to go steal a pound from a buddy. I'll get her honed in. Thanks a bunch guy!
 
Very welcome, should be very consistent if you load in the middle, hence testing out a little below your first load to make sure it still looks good at those speeds. I like benchmark because you don't lose a lot of speed using a lesser charge.

I was looking back at my data from several years ago with 8208 and the 75 vmax. There's a little sticky note that reminded me about vertical flyers using the 8208. It looks like it started about 1.5 grains under max and was never cured.

I'm able to ring 1.5 MOA steel year round using the same load and same drop chart year round out to 600.

That's all the room I have.
