Hi, New member here. Joined to discuss this topic, I have read good info MANY times here in the past so figured it was time. My situation and thought as follows. I have reloading experience, I load 348 win and load heavy 357 revolver for the hunting I do in MAINE. I got a sweet deal on a Browning A-Bolt Stainless Stalker chambered in 30-06. Now while the 30-06 is a fantastic cartridge, good for both deer and black bear, I find this gun to recoil a bit more than I'm comfortable with. My 348 doesn't bother me but its most likely heavier, fits me better, or both. So my last trip I load up some "light" 30-06 loads 165gr speer BTSP over 54.0gr of IMR4350 that per Speer load data should run about 2500fps. (This is a handicap 30-06 load which is really on the higher side of 308 winchester loads.) They did shoot real nice and were lets call this the max recoil I want to deal with in the A bolt platform (which I really like this model). So the 165 30 cal bullet has a lesser Ballistic Coefficient than the Heavy 30 cal bullets like 180s 190s which will perform better and kick more. What I'm getting at here is if I am going to shoot 160 to 165 grain bullets EXCLUSIVELY I really think I should be looking at a 280 remington. I dont mind it being a gun I have to reload for to save money. However I dont want it to be a 284 win thats seems so far forgotten its super difficult to get brass and components. Plus the A bolt is not available in the 284 win. I was on the search for a while for the A bolt 7mm-08 but if i plan to shoot 160 and 165s all the time I feel I'm crowding the powder capacity too much in this caliber. I dont want to feel undergunned in the woods either. 280 remington seems ideal for my application. 160 to 165 gr bullets. Large Maine Whitetails and occasional Black Bear. SO HERE IS MY QUESTION All things being equal (rifle weight,model, etc.)besides bore dia, comparing a 30-06 to a 280 rem, with a 160gr bullet at 2750fps WILL THE 0.284 RIFLE KICK LESS? When i look in the reloading books I read that with certain combos of powders. The 30-06 and 280 Rem can push the same bullet with the same case pressure of roughly 48400 CUP (IIRC). Many sources state the bore dia has no effect if the projectiles weight the same. Force = Mass x Acceleration Pressure = Force / Area Please help me wrap my head around this. I dont want to spend time and money changing rifles, calibers, reloading equipment to end up with the same results. Like i said the plan is to never shoot a heavier bullet than 165gr. I would like to try my share at shooting over 200yds but reality is the gun will be shot under 200. Maybe up to 400 at targets if I do any good with it. Thanks in advance.
