Bit more on the why of the question.
At the moment I have the 30-06 and 45-70 like you saw in my sig.
Finding these days I really don't use them enough to warrant having both. I kind of end up picking one because I haven't used it in a while and go back and forth like that.
Still want a 'cover all' calibre, something for game at distance, and I'm looking to start reaching out a bit further at the range for fun and in some field shooting.
Plenty of calibres that will do that, but the misses likes a shoot now and then too, so figuring her in a bit. The 45-70 about knocks her over, 30-06 is ok for a short stint though.
Trying to keep recoil around/under that is why.
THERE IS NO FREE LUNCH....
you can apply that to many thing in life including shooting. If you want "more oomph"... you're gonna get more oomph!!
You cant satisfy the lower recoil requirement for the wife (if her technique is good, and she doesnt shoot off a bench (what even is that??!) she'll be right....my 'boss' like the 375HnH, no probs, yet the free recoil is up to twice the '06....
Recoil force is determined solely by 4 factors/variables;
1 Velocity of the projectile,
2 Mass of projectile
3 Propellant charge
4 Mass of the rifle (inversely - more mass less recoil)
So yes, you can theoretically have more oomph but you would need to damp it down with lots of countering rifle mass... (I posted the recoil calculation somewhere else...if you want to have a play with the numbers)
As far as trajectory goes, it is determined by ONLY 2 variables[all things equal, climatic conditions elevation, location on the earths surface and direction of projectile(Brett! haha)];
1 Velocity of projectile
2 Ballistic coefficient
So if you had a 50cal projectile with a ballistic coefficient of say, 0.6, alongside a 22cal projectile also with a BC of 0.6, launched them both at say 2500fps.... they would follow the identical trajectory....of course the heavier one would retain more energy at any given distance....
1 Projectile VELOCITY
