    I'm about ready for another bottle of powder. I'm using Pyrodex RS right now. It's the equvilant to FFG. So, is 777 better? what about performance? Will using 777 in the loads I've got dialed in now be thrown off if I use the same amount? Thoughts?

    Yes it will be different, 777 is a bit more denser in weight and more potent. Dunno how much however

    777 is much cleaner can be cleaned w water and not corrosive as pyrodex

    which is better? i dunno

    777, cleaner- less sulpher- and yes start low and work charge up to best grouping! I'd say load same as u are and shoot 3 bullets at 75 yds then see if group is tight or need to back down a Lil bit!

    [rquote=1868441&tid=130068&author=Rebel]if i recall approx 85 grains is similar to 100 of pyrodex[/rquote]Yeah real close! I shoot 90 gr t7 with a 200 gr t/c ballistic tip made by Hornady, same as the SST and have a 4.5" rise to fall point of impact out to 200 yds!

    right now I've got a pretty decent 3-4 inch group at 75 yards with 80grns and a 295powerbelt hollow point. If I go to t7, use maybe 70 grains?

    [rquote=1868456&tid=130068&author=Mastevt]24 inch's from barrel end to breach plug. 1:28 twist.[/rquote]I wouldn't drop below 80 IMO, but it may close ur group up some, and I use whinchester primers labeled for t7 they fit better I'n my breech plug and less blowback!

    Scott....I know I'm preaching here but a 3 to 4 inch group at 75 yard....?? I know you can do better using the right components. I have some extra Hornady 300 gr. XTP MAG with Harvester Sabots that you can test out when you buy that new bottle of Triple 7 FFG powder. I'm using the Remington primers also. I guarantee that you will get your group down to at least a 2 inch three shot group at 100 yards.

    Here is what my Knight KRB7 .50 cal. will do at 100 yards using the Hornady 250 gr. FTX with 110 grs of loose Triple 7.

    Thanks MM. I got a few Hornady's left in 250gr SST/ML. I just got off the phone with Inkwithattitude. Nice guy. He's giving me some ideas to look for. I gots to get this ML cleaned up now. Got the kids fed and Brandon off to the game, so now I can clean guns.:D

    I like 777 just because its easier to clean and no sulfur smell. Because I don't have a basement or garage sink I have to clean rifles in the kitchen and my wife appreciates the no smell factor. Soap and warm water is all you need for 777.:cheers:

    I don't think 3-4" groups at 75 is half bad. :02:
    There's a lot more people with muzzleloaders that shoot those groups than shoot smaller.
    Can it shoot smaller, yes. Is it needed, no...


    I like 90 grains of RS and it typically shoots all bullets pretty good. It's always been the popular loose powder measurement for years (for bullets/sabots anyway).


    I've always shot RS in my rifle and the only complaint is that you do have to clean it within about 2-3 days before damage occurs.
    I use 777 in my cap and ball revolver and go 2 weeks before cleaning and it cleaned up like new. I'm not suggesting that time for you but you might be able to load it the night before the season, shoot it a couple times, and clean it after the season is over. Triple 7 might save you an hour or two.

    I'd see what 85gr of 777 does :thinking:

    Just remember that 3-4 Inch group at 75 yds is gonna be 12-16 inch at 150!!! Most people don't realize that, find ur bullet and powder combo that blasts a awesome group at 75 or hundred and u will be dumping them what ever range you shoot!!

    I agree with the Triple Se7en recommendations. I'm not saying it won't kill a deer, but I would suggest more than 70 grains. I usually use between 85 to 100 grains for my TC Encore and it shoots TC XTP's pretty well with that.
