Beiruty, valid question. I intend to shoot what I consider rather large animals in the near future...elk sized animals which I may need to take at a distance greater than 100 yards, and for which I'd prefer they drop with one shot. I realize that shot placement is more important than bullet size in general. And of course a big thumping gun that has lots of recoil isn't typically helpful in getting great shot placement (if you anticipate the monster recoil). That's the main reason I'd like to shoot someone's gun in these calibers, to see how "bad" the recoil is. But, I'm aware of plenty of people using these calibers who don't seem to have any problems.
Regarding ballistics, I've been doing a lot of research and if you believe Hornady's ballistics chart then:
A .30/06 150 gr SST has velocity of 2,627 fps and energy of 2,298 ft/lbs at 200 yards. But I'm also looking at the bullet trajectory, and if zeroed at 200 yards you have to hold 1.4 inches low at 100 yards, right on at 200, and then hold 7.6 inches high at 300 yards.
A .300 Win Mag shooting same bullet has 2,802 velocity and 2,615 energy at 200 yards. And again if zeroed at 200 yards, hold is 1.1 inches low at 100 yards, right on at 200, and 5.6 inches high at 300 yards.
I had to use a different source to look at .300 WSM and .325 WSM characteristics, but generally speaking they're very similar to the .300 Win Mag's...lots of downrange energy and very "flat" shooting".
But of course, the question is, is this downrange energy, and this "flat shooting" significantly better than the .30/06? Better enough to justify buying a new rifle? Better enough to justify the recoil? I don't know. That's why I want to try shooting one of these calibers, to help shed light on these questions I've been grappling with.
And for the record, I'm comparing all these calibers to my Remington 700 .30/06 BDL. It is a beautiful old gun, with real wood stock, and real character. I'd prefer to stick with it, after some accurizing work and a new recoil pad. (Basic plastic pad now, so it thumps pretty good)
Thank you for the thoughts. I welcome more. I'd like to do this right the first time. I'm all ears...
