FROM YOUR POSTS:
“The one factor could be I switched from a CCI 250 to the Fed 215 on this box.”
“Other than the ammo being 13 years old & having a new stainless 26" barrel on the M-77, I've shot this same load for decades.”
“That, and it was 85 degrees today @ the range. Most times I shoot it, 45-65 degrees.”
Three strikes and you are out! But you were very lucky. Should have bought a lottery ticket on the way home.
REMEMBER:
When you change any component, drop back to an entry level load and work up.
New barrel = new chamber = new gun=start load development again.
Don’t shoot cool weather max loads in hot weather.
We are glad you posted this to help us watch our loads too.
Thanks,
