Just bought a new Omega and will go to the range next Monday. I have Pirodex pellets, but want to try loose powder. Nobody within 70 miles of me did not have 777 FFG in stock so I bought FFFG. I do not have experience with shooting loose powder. Is there something to know about measuring or amount of load of FF vs. FFF. I know that FFF is finer powder. Any input will be appreciated.
Since you were originally shooting Pyrodex pellets, the first thing you need to remember is loose Triple Se7en FFg is approximately 15% stronger then Pyrodex in pellet or loose form. Since you purchased Triple Se7en FFFg, it is able to produce even more power & BARREL PRESSURE.Although the increase in velocitybetween the FFG and FFFg in the Triple Se7en's is not as great as many believe.
If for instance you were shooting 100 grains of pellets in your Omega, start your testing out at 80 grains of Triple Se7en FFFg and then work your load up from there. Do not exceed 120 grains of the loose powder in your rifle. Not that I would fear the rifle will blow, but there is no need for it and it will be all the bang you're going to need unless maybe Cape Buffalo are the quarry of the day. 120 grasin of loose powder is very powerful. Most people shoot 100-110 and find that plenty. Only your rifle will tell you where to stop.
When I shoot my Black Diamond XR with T-7 FFg and a Shockwave, I shoot 110 grains of powder. When I shoot T-7 FFFgI shoot 100-105 grains of powder.
Also you might experience a slight crud ring in the breech when you shoot. Be sure and swab the barrel between shots for your best accuracy.
