100 grain Hornady Interlocks - was the go to bullet for my 25-06. I tried SST’s and they were a miserable failure.
I’m going to go with partitions in my 257 and the 25-06, I believe.
I’m going to have to do a lot of testing with my 1 in 14” 250”. Ken Waters wrote that the 1 in 14” twist will shoot 100 grain bullets fine. Others say it won’t. I have 87 & 100 grain hot cores. Some 100 grain partitions. I have my eye out for some Sierras.
I’d like at this time to give a sign of my middle finger sticking up to the new Hornady management.
Good luck on the Sierra, especially if Prohunters as I believe those are discontinued.
