Quarter bores never caught on much for LR shooting and because of that it lacks optimum bullet choices. The 115gr Berger hunting VLD is pretty much the only game in town for a bullet with a halfway decent BC of .466. Everything else is .430 and less.
I just picked up a sendero in 25-06 from a trade I was thinking of re barreling it but I think it fits the bill for what I want a flat shooting round capible of taking out deer and predators at a medium distance.
I love my 25-06, but as mentioned, it has no good bullet selection. If somebody (cough, cough) would make a 120-130 Amax or Match King, I would build me another .257 in a second.
Thas what I was afraid of I'm looking into my first custom build so I am probably going to stick with a 7mm mag of some sort. I don't hunt it is for F-class basically
Unless you are completely recoil insensitive, I'd look downwards from the maggie calibers for F class. Go online and search the winners lists for the class and build accordingly. JMHO
