That missed the 1 inch target by about an inch at 350 yards. That was a perfectly clean bore.

This was shot taken 9 days before that one, with a copper and carbon fouled bore. Same distance same target with less than 1/2moa deviation.

Other loads I've developed will have a POI shift/ accuracy drop. This one is about 2moa.

I'll skip the second shot and go to the third.

If I would have kept on shooting it would have fouled to the condition that shot well, but since I don't want to waste reloading components, I don't use that load anymore.

I now load develop in an attempt to find loads that don't have a clean/fouled bore deviation... and have done so successfully in all my rifles. The sniper you speak of simply doesn't have ammo tailored to his specific rifle.
Oh I see very informative, thanks.

Nice video dude! I have a 94 and I sure wish I could shoot it that far. Pretty cool how you could see the bullet in mid air.

Thank you!

Twice a year at my range, the sun rises in just just over my left shoulder and I set my camera just over my right shoulder, and the reflection of the sun off the base of the bullet is bright as can be.

Thanks again!

Default copper fouling

Thanks to all. Though pro and con you set a direction. Loved the '94 400 yarder!
