eldeguello is exactly right............ The Goex ClearShot is VERY anemic - even the 3fg version will barely launch .44cal round balls out of my revolover.........and forget trying it in the rifle. If you try the Triple 7 - you will notice a BIG difference in power....approximately a 30% difference compared to ClearShot.

For the big Maxi' s you' re talking about shooting, I would start my load workup at 60 or 65gr of 3fg Triple 7 and go up from there until you' re happy. I think you' ll find that the 777 will offer less of a fouling problem than the ClearShot. I' ve found that ClearShot leaves just as much fouling as regular Goex BP, it' s just easier to clean out - but 777 seems to leave a little less total fouling, but the fouling it does leave can get a little " crusty" if you leave it too long without a wipe.

AS far as whether to use the 2fg or 3fg - with 777, I doubt it will matter too much in your .54cal. There is very little difference in velocity between the two with identical bullets - usually 50fps or less (according to Hodgdon' s data). I have found that my .50cal in-line does like the 3fg when using sabot bullets of 350gr or more - but I' m not sure how this will translate to a .54cal shooting conicals. I will say this much, if you fire a 400+gr bullet with 90gr or more of 3fg 777 - HOLD ON, cause it is gonna kick like a mule! Triple 7 is just that hot. And remember, if using 777, to take into account your gun' s maximum rated powder load. If the max is 100gr of BP - then your max charge of 777 will be 85 to 90gr.

BTW.... ClearShot is currently out of manufacture. Goex had an " anomaly" in the plant that was making it - that plant no longer exists . I talked to a Goex Representative a few weeks ago at the NRA Convention and they are planning on producing it again, it just ain' t happening yet. IMHO, it' s return may rest squarely on the popularity 777 gains or doesn' t gain.
CleanShot is " Kinda" out of business. They have been resurrected under the name American Pioneer Powder - same stuff, but a new name........plus they offer powder " sticks" instead of " pellets" to keep Hodgdon off of their backs. Personally, I like CleanShot loose powder for in-lines.......it is cleaner than any other powder and only about 5% less powerful. But it is cut into BIG granules, making it tough to ignite in sidelocks - and it tends to attract moisture badly. A fresh can of powder can turn BAD literally overnight.
