Target & Plinking / Rudy Is Right
« on: March 12, 2014, 03:47:52 AM »
For years people had been writing that a 28 grain charge of 3Fg was the sweet spot for a Pietta Remington revolver accuracy wise.  They stated that anything over this, accuracy diminished. 

Others said the competition shooters use 15 grains of 3Fg and 25 grains of cream of wheat to get the ball just under the end of the chamber and use grease over the ball for lubrication.

Then fellows with a name behind their claims like Rudy said to use 35 grains of 3Fg and a wad for power and accuracy.

So yesterday I set out to test these ideas and came up with 14, 5 round groups to shoot at 25 feet for this battery of tests.  Two patches sprayed with Ballistol were run down the barrel between each 5-shot string.

The first 4 targets of 5 rounds each were to use cream of wheat to fill the chamber over 15, 20, 24 and 30 grain charges of Schuetzen 3Fg with grease over the balls.  The best 5-shot group by over an inch went to the 15gr charge at 2.44.  Eliminating the flyer, the best group went to the 30gr charge which came in at .88.

The next 4 targets still used the cream of wheat but now included a lubricated wad instead of grease over the ball.  Again the 15gr charge won at 2.38 for the 5-shot group and the 24gr charge won the 4-shot group at 1.13

The following 3 targets were grease over the ball only, the round seated directly on top of the black powder.  24, 30 and 35 grain charges were used for these six tests.  The winner of the 5-shot group was the 35gr charge at 2.75 and it also won the 4-shot with 1.19 grouping.

Finally, it was the wads turn to run solo and again the 35gr charge came out on top both times with tiny 1.13 and .88 groups respectively.

This gun likes the extremes, 15grains for plinking and 35gr for max flame and boom.  When that thing went off at 35 grains, all other shooters stopped to watch!

The next battery of tests will reproduce the best 35gr loads at 25 feet and then at 50 feet.  Then the gun will shoot the better of those two at 25 and 50 yards.

I will likely run this again or something similar as the Schuetzen is about gone and Olde Eynsford is expected to replace it.

Rudy is right!

Rules and Administration / The Percussion Revolver Group At Yahoo

Thanks Joel for stepping up to take over that forum!  Greg has done an outstanding job of keeping it focused and providing historical information along with modern advancements with regards to our cap and ball revolvers.

It is my hope that a lot of the posts and or information from that site will be imported here for posterity. 

I like the Yahoo forum as it basically resides in my Outlook Inbox in its own folder.  Should that crash it's all gone save for what I cut and paste to documents for future reference.  This format organizes the information on the net and is more versatile and user friendly though in ignorance, do not know if it can host photos and documents.

Thanks again Joel for taking the reins and let us know how we can help if need be.
