Brass can make a difference in precision

[clearwater]

Loaded some 223 grain cast bullets for the 30-06. 25 grains Reloder 7. Seated to the lands. 100 yards with some wind. Everything the same except the brass.

Top of photo old military brass I found at the range. Foreign stuff with a 1969 date.

Bottom same load but with RP brass. I stopped shooting and will pull and reload the mil rounds into the RP brass and see if they continue to shoot better.

Brass definitely can (and does) make a difference in accuracy. Great reminder!

If the old military brass was from mixed lots or various manufacturers, then the test wasn't very fair. I've reloaded military brass and had very good results but .......... switching to Lapua cases did result in reduced groups. The reduction was not as much as you'd expect.

I have experienced better groups by switching brass. I use three brands of brass, from best going down would be Lapua, Nosler and then Norma. I have ditched Hornady, Remington, Winchester and Federal brass back in the days for some of those reasons. Some of the other reasons are cracking at the neck, loose primer pockets after a very low number of firings, inconsistent case volume and badly dinged case mouths upon arrival of the product.
