Bullets I have on hand are 40, 55 and 60gr Vmax, 70, 75 and. The load data I had originally used to determine my charge weights gave me very low velocities. I also got IMR 3031 which also is used for a wide range of bullet weights. In this video I revisited some load development using H335 and a 62gr Hornady FMJ bullet. 223 Rem at lower pressures than most other Hodgdon propellents they list so I picked up a pound. If you get a suppressor, this load will also be slightly quieter & slightly less wear & tear on the can. Hodgdon data indicates this can be used for everything from 40gr to 77gr. The Hornady actually costs less at $0.16/ea which gets you to $0.225/each.īy Adjusting your load components, you can actually decrease the cost of the load (even down from $10/lb surplus powder), significantly reduce muzzle flash, while maintaining the exact same energy levels, while using, what I believe to be, a better projectile for hogs.boy, I hope my math was right.oh well, been embarassed before. This would only need 18.1 grains of powder to push it to 2440fps & the same 990ft lb e of your H335 load, and 50,000psi chamber pressure. Using the same N120 powder, but a 75 grain Hornady projectile loaded to 2.25"COAL can get you down to burning 100% of the powder in only 8" of barrel. They necessitate smaller powder charges, which means you have less to burn from the start, and they spend more time in the barrel, which has the side effect of giving the powder more time to burn. You might also consider Heavier projectiles because they increase powder % burn in two ways. More expensive N120 would push your cost up to $0.276This N120 load should burn 100% of the powder in 13" of barrel Runing N120 & Nosler 55 BT at a longer 2.25" would only need 20.4grains to get to the same 50,000psi chamber pressure, and should go 2,850fps & get 990ft lb energy. The longer BT takes up more case capacity which increases chamber pressure. Your 55g Nosler BT is 0.810" long, while their Hornady 55g FMJ is shorter at 0.735". So QL almost exactly matches their velocity claim. Running their load thru QL nets 3,122fps at 50,000psi chamber pressure. Their manual lists it using Hornady 55grain FMJ at 2.244"COAL with a max of 20.7grains. It is much faster & burns 100% in a 16" barrel What fps do you actually get?This load probably costs you $0.20 for the bullet & $0.0364 in powder, if your using surplus powder. QL says your running about 47,000psi chamber pressure & should be getting about 2835fps & 982 ft lb energy. So you have 1.7grains of burning powder leaving your barrel (24g x 7% unburnt powder = 1.68g) Your load: 24grains H335, Nosler 55g (0.810") should burn 93% of the powder if using a 16" barrel & 2.25"COAL I use Quickload to play with subsonic & suppressed loads & to learn what "normal loads" are doing
