Yeah, Im with James on that one. I really like my 25-06 Ackley imp. Its a real neat cartridge, I pretty much use my for varmints and long range plinking. I have used it for deer. I too have a lilja sendero weight barrel (3 groove) 1-10". It really shoots the 100 grain matchkings well,with Imr4350. Right now im using Norma 270 win brass, you can also use Lapua 30-06 brass if you want to go with a high quality brass. I have the rifle throated for the 87 speer tnt, and I know that rifle will shoot under 3/8", if only I could.
