After much thinking (and smoke spilling out of my ears) :) I came up with my latest outside the box idea.

Heres the question:
Would a 30-06 handload with the 180 grain Barnes Triple Shock X-Bullet (boattail) at 2700 fps match the BDC cam on the Leupold M3 scopes for the 180 grain 30-06 at 2700 fps? Or does the TSX bullet differ so radically from other bullets as to not match the trajectory on the BDC?

Heres the idea:
A custom 30-06 bolt action, with a Leupold Mark 4 LR/T 3.5-10 M3 intended to shoot the above mentioned handload for almost everything.

Supposing the BDC matched up with the load's trajectory, what would be the ideal barrel length and twist rate this handload?

Since I'm not quite the ballistic genius I wished I was :) I'd appreciate anything anyone has to say.

Thanks in advance!

if its set up for a differnt bullet the points of impact WILL be differnt
how different will depend on the bullets and ballsitic coefficeint
every barrel type will give slightly better velocities and that would depend on how much powder and what type of powder you put in your handloads

If you can match the BC and velocity it will be very very similar. Even though its not exact, the BDC's are not precise either. I did that exact thing for a .223 and decided it was pointless. I sent my leupold LR/T M3 3.5-10 back to the factory to have m1 dials installed. Id deffinately go with the m1 dials after trying both of them. That way you can more precisely make a shot and site it in. And it takes barely anymore time to turn the knob 4 times as much. If you have a balistic card of a particular load, its just as fast.
