Ammunition: contemporary information

(You need to Login or Register to view media files and links) with contemporary information relating to ammunition / loading for long range shooting with the muzzle loading and black powder cartridge rifle is available on my web site. Historical reference material rather than hands on reloading guidance.

David,
You are to be commended for all the hard work you have put into your website for the BPTR shooters.  I have had a long interest in what Metford was doing with barrel rifling and bullet alloys for a long time. What I especially find interesting is your report on his bullet alloy experiments where he could change the elevation 3 ft in 600 yds by changing the bullet's hardness.  I've suspected this for sometime, that nose shape has less to do with elevation than has been reported on another website.  Rather it's nose upset that can quickly change the b.c. of a cast lead bullet rather quickly if it isn't perfect every shot.  In otherwords, the nose bumps up off center.  That along with the center of pressure where it changes as velocity decreases which I have very little understanding of.  This may have had something to do with the success of the Metford shaped bullets which are now, in various forms, called the "money bullet".
This last year, I played with an alloy using antimony and seemed to have fewer unexplained fliers at 9 - 1000 yds. It's virtually impossible today to practice at long ranges over here so having only 3-4 LR matches to attend limits experimenting to the match itself.  Not easy to do when you're trying to do well in the match itself.  Bob

Bob,

I share the same issues as you when it comes to long range load development / experimentation; pretty well all of my range access is in competition. 

It is an endlessly engaging subject that I doubt anyone has the time/resources to pursue these days as some of the 19th century riflemen did.

Check out the groups shot with NO lubrication!  Kind of flies contrary in the face about using lubes and the constant discussion which lube is 'best'

The frustrating thing about that report is that where lubricant was used it does not say of what it composed!

John Boy,
It's hard to tell from those old readings of what is meant by no lubricant.  While reading Walsch's book, "The Modern Gun and Sportsman's Rifle" written in 1884, it is noted that Metford was striving to shoot accurately to 1000 yds.   At that time, they were shooting for the "Duke's prize which required 15 shots without wiping out.  One of the cartridges Metford worked with was the No. 2 Musket which was a bottle neck.  It held in excess of 90 grs of powder and was said to carry no lubricant but the cases seemed to be loaded with 2 felt wads surrounding a lube soaked wad.  There were also card wads used but I can't remember the order off hand.  At that time, I don't know if that was considered a lubed load or not.  It may have required a lube cookie to be considered a lubed load.  
As you mentioned, a lot of this flies against everything we're doing today.  Bob

I was not thinking out of the box!  I shoot BPCR reloads all the time with just a 1/8" LUBED felt wad.  No leading and accuracy is maintained
Two years ago, 38-55, 42grs KIK 1.5 or FFg, Ideal 375166 and a 1/8" felt wad.  Shot 5o consecutive rounds with no tubing or patch, 200 to 500 m ... with minor sight adjustment from prior year.  One water cotton ball and 3 dry - last ball had little foul on it
