While we're still discussing: I just went through my safe today and rediscovered a Shepherd scope in the back of it. It's practically brand new, it's an older model.
Something I didn't really add into this budge was the cost of quality glass. I could steal something from one of my other guns, but I really dont' like doing that. If I wanted to use this scope, here are the ballistics it'd need to "match."
0"@100, -10.12@300, -39.6@480, -71.03@600, -107@700, -153@800, -212@900, and -286@1000yrds.
The only thing I could quickly find was the 300 Win Mag, loaded with a 130grn at around 34-3500 fps.
EDIT: I found another caliber that might fit the bill. the 270 Weatherby Mag. I can order ammo for it and develop a load for it later on.
I still really like the 260, but if I could save some money by not having to buy some optics that'd be great. Plus these weatherby mags are so alluring with their fps and flat trajectories. The 240 weatherby mag is also a contender, but it seems like the 270 will do the same speeds with a heavier pill. I also really like the 257 wthb mag, it seems like a really good in between round. For overall performance though, with a 130grn I think I can't go wrong with the 270...but maybe I don't need a 130grn!
Back and forth and back and forth, too many options; thank you guys for your patience.
