Why is this off?

[Jonathan_S]

I would probably...

#1 Have somebody else shoot it
#2 Re-mount onto the stock

One more thing that came to mind...  I have had difficulty switching between lead core and Barnes without cleaning the barrel.  I can run lead core behind a Barnes no problem, but not in reverse.  So makes me think to ask; were the first shots Barnes after a previous session being a Nosler or something lead core?

That is interesting. I wonder what causes that to occur.

I was shooting lead core before switching to Barnes. I didn't clean the bore before I switched.

The Barnes group well, but take 2-3 shots to start grouping. Those first few shots are always way off. I've been out on 4 separate range sessions and observed this behavior with the Barnes.

Good call Rad.

Good call Rad.

Yes indeed.

I called Barnes tech support and he said that some barrels don't do well if you mix lead and all copper because of how the barrel picks up different metals. Suggested a thorough cleaning then shooting all copper and reevaluating.

Or not shooting Barnes  definitely the route I took

I second the dropping Barnes idea.
I also try not to shoot different types of bullets without cleaning. Especially during load development. I even avoid different types of powders during development without cleaning

[wooltie]

Haha yeah....especially when you get irritated and shoot a different load just to prove that "it's not you" and the other load shoots a quarter size group at 200 yards.

   Graphite coated powder or copper bullets will really mess with other powder / bullet results.

You missed quoting the most important part of my post!

Thanks for the input from everyone. I didn't know about the effects of mixing powder and bullet types.  Makes sense.

i don’t have any evidence that powder differences will affect much but it would just be another variable

True, but if that does affect your rifle then you limit shooting to either all copper or lead core. Makes for expensive practice.

I use the same ammo all the time regardless if I’m hunting or practicing or just shooting to shoot. Practice like you play

agread. One reason why I like the hunting vld’s.   Typically once I find a load I like I stick with that combo for the life of the barrel
