Then you use a Lake City case(military surplus), the same bullet, using a standard Fiocchi Large Rifle primer, that groups out of that rifle very nicely. But almost every other load, the Federal cases work quite well.
I will also note I tried some subsonic loads in .308 using the 190-grain Hornady Sub-X bullet and Titegroup powder, and some 169-grain match bullets I picked up a while ago from Midway(blemished bullet sale, can save some money), and based on past experience I dropped the powder charges by .2 grains on the first, .3 on the second, and both were still right at or a touch above speed of sound. I don't know if because the test barrels they use make a difference, or they'd rather have a "Let's make sure a bullet doesn't get stuck in their barrel" precaution. So next batch will be a bit lower yet.
But it was a fine day to be outside, and I'm glad I went.

I have been reloading for 60+ years. The changing of a single component making a difference is the mystery of the art.
Resonant frequency. Every barrel will have a resonant frequency that is also part of the accuracy formula. Check hodgdonpowderco.com for a burn rate chart. I have never tried Titegroup in a rifle, burns way to fast.
A pistol may have a resonant frequency, but the barrel is to short to have a great difference.
I have a Remington BDL 25.06 that I worked for varmint hunting, with loads for 75g, 100g, & 120g bullets. It will shot dime size groups at 100 Yds. If there is a miss, it's not the rifles fault.
It has also been glass bedded and the barrel was cryoed.
It was brand new out of the box, so I did a barrel break in of shoot 1 clean for 30 rounds, shoot 3 and clean for 30 rounds, shoot 5 and clean for 40 rounds. Making 100 rounds before any changes were made. Be sure to use a good copper cleaner. When the patches stop turn blue, the barrel is clean.
