I want the utmost confidence in my hunting load, so that I know I’m making an ethical kill.
Negative sir, but I've never had lot to lot inconsistencies with any Hornady bullets I've used for any of the calibers I load for. On a better note. Dropped to 53.5 grains and it's shooting right back to where it did with the last batch of brass at 55 grains.
Couldn't agree more. Once I get paid I'll be making the switch to lapua. Can't put a price on a animals life, I wanna know everything is signing tight when I send em downrange, every time.
Did not go through all the thread, sorry if I'm repeating others;
1- Scale calibration. Hopefully, you have some ways to check the calibration of your scale. I have high-end mechanical scales as well as auto-dispensers and electronic scales. Many years of frustration... Recently upgraded to A&D Engineering FX-120i; the world is definitely a better place now.
2- Velocity. I think you should invest in a chronograph, will tell you a lot.
3- Weigh your brass and bullets, see if they are the same between the two batches with different groupings.
Good luck, hope these will give you some ideas to build on...
I did with virgin brass. Then this just happened. View attachment 424722
How do I go about that?
John Barsness recited a tale in his Gun Gack book, about a friend who would load for his 7mm RM using only new brass. With one new batch of brass his accuracy went to hell, and he couldn't figure out why. Turned out the case necks weren't annealed properly from the factory. After he annealed the cases, he went back to shooting tight groups.
I have never done h2o tests. My rifle will shoot just fine between brass batches. When switching powder lots with H4350, I had to drop .1 grain to match fps.
This is for a hunting rifle correct? If yes then don’t bother. Should be able to get 1/2 MOA with Hornady brass. Or at least I do. Other things are wrong.

You’re just doing a comparison between the cases that caused you an issue and the ones which didn’t. As long as they’re all in the same state, it doesn’t matter what state that is in.
That is a big difference in charge.
I compared a old still new case I had prepped with 55 grains in it, the powder is almost to the bottom of the neck. Then put 53.5 grains in a new prepped case and it was almost to the bottom of the neck in the exact same spot. Why do these Remington cases have so much less space than the old ones? That's some atrocious quality control if you ask me.
I'm not sure, thats terrible. Maybe they sized the body way too small. I would compare a once fired old and once fired new. Clean and see how they look. When you size the body, FL or body die, see how they feel compared to each other.
When I mess up on bumping with my body die, or accidentally seat too deep, I sharpie foul on the outside of the case. They still shoot well under 1" groups and 100. Mind you I'm not too far out of line in the measurements.
I have Remington brass that I use for my 270, never had trouble with it, that rifle's best group was 5/8", but it only did it once, 3'4" once as well. Usually 1" and never really over. I have revisited that rifle, tweaking it and am in the middle of working up a new load. When hunting is over I need to have a closer look at the brass, Im sure I have new in bag, different lot#'s. Bought them way back when from WholesaleSports.

Oh man you guys talkin bout bumping and stuff is way above my pay grade haha. I send'er all the way home to factory specs cause I play it safe like that and don't get carried away with .
