I don't remember the formula for it, specifically, but in layman's terms, the force of the round on impact will be determined by a combination of weight and velocity. The more you have of either, the more force you'll have on impact.
Well, my answer did not get here quite as fast as the previous statements. It was long, so I'll try and make it quick...higher grain ammo does NOT mean that it is more powerful. All it means is that it has more weight to the bullet, but there are MANY factors that make a bullet more or less "powerful" such as bullet and case design, type of gun powder and primer, etc. Plus, in what context do you mean "power"? Power could be penetration, superior ballistics, lethality...etc. Good, but complicated question.
standard 115 grain 9 mm ammo or higher grain bullet.
You may use any 9mm Parabellum (9mm Luger) cartridge that is standard or +P, including 124 grain ammo. Recoil may be higher than with 115 grain ammo. Do NOT use a +P+ cartridge.
The 147 and 124 grain are bullet weights. The 124 grain bullet loaded to higher pressures (+P) will have a higher velocity than the standard load with a heavier 147 bullet. As far as penetration goes, I have seen tests where the 147 grain out performed the 115 grain +P but the 124 grain +P should be a good all around round.
115 grains is the weight of the bullet.
Yes, but Compact has more ammunition and subs (ammo in reserve). The 140MM Sidearm has lots of ammo and subs and is also powerful. The USP only has 12 ammo and 100 in subs but can be silenced. The ES Five Seven is powerful with lots of ammo too. The Dual Elites are quite good with fast speed and some power and ammo in total. The Nighthawk, however different, has hardly any ammo and subs (7|35), but its bullets can be quite powerful and especially powerful with headshots.
Possibly the Winchester 110 grain Silvertip. The 125 grain Silvertip is a +P load, the 110 is not.
150 grains plus preferred, but not the Buffalo Bore 190 grain hawk bullet ones, as the are not made to properly mushroom on deer. The 30-30 is the all time #1 gun for deer hunting, and virtually everyone makes ammo for them...but I always leaned to the Hornady 160 grain FTX LeverEvolution or the Federal Premium ammo. You will have to buy as many different brands of ammo as you can afford and shoot them all to see which your rifle prefers. I would not go lower than 120 grains. Fixdeluxe1's Improvment:If you can get it,I recommend 150 Grain and up.Try Winchester ammo its one of the best and if Remington does 30-30 them too.
30/06, 150 grain
230 grain round nosed FMJ.
It fires the 5.56x45mm cartridge. It is compatible with the 62 grain M855/SS109 ball, the 64 grain M856 tracer, blank cartridges, and it can use the 77 grain Mk. 262 cartridge. The slow twist of rifling (1 in 7) makes it impractical for use with the older 55 grain M193 ball ammo and 45 - 55 grain commercial .223 Remington loads.
Winchester 150 grain 30-30.
Remington .270, 150 grain.
