Id like to try a 7mm-08 but am worried what kind of trajectory I will have with the larger bullet and speed loss from the short barrel.
I just don't like the idea of possibly wounding a deer from being under gunned or from a bad hit from poor trajectory.
Is there a magic factory round that I could sight in 2" high @100yds and have a 8" or so low POI and still have sufficient energy?
You will lose about 300 fps with handgun lengths.
A 7mm-08 will take you to 300 yards just fine on deer.
The 25-06 in handgun will have the approximate performance equal to what 25 Souper (25-08) or a 257 Roberts would in a rifle--Yes, it will do the job for you.
The 260 Remington, 6.5x55 Swede, and the 6.5-284 will do everything you want in the .264 bore.
270 Win, 7mm-08, 284 Win., 280 Rem, and 280 AI will take care of business in the .277 & .284 diameters.
My old 14 inch 7mm-08 XP had a MV with 140 NBT's of 2540 fps.
At my elev (4600) with a 200 yard zero, I will be 2.3 inches high @ 100 yards, -3.7" @ 250 yards, and -9.2 inches at 300 yards
IF, I make my zero @ 250 yards: 3.8 high @ 100, +2.9 @ 200 yds, 0 @ 250, and -4.8 inches @ 300 yards.
With this load, which was a light load (choose it for its accuracy) , 225 yards would be closer to an ideal Zero. FWIW-Took whitetail, antelope and mulies beyond 300 yards.
