Hey fellas:
I went to the range yesterday with my Uberti Hiwall.
I loaded up 20 rounds of my usual bp loads, except I topped them off with
boolits cast of ww alloy +2% tin. The boolit is the Lyman 457125 Government.
The boolits weighed at 516 grains sized and lubed with Emmerts recipe.
I started with the bore clean, and run a dry patch through it t get rid of most of
the residual barrel oil. I also dried the chamber.
First five shots at 100 yards went into .850 center to center. I checked the muzzle
between shots to check for leading. Temperature was 75* and humid. I
blew 4 good breathes between shots.
I could see gray streaks at the muzzle beginning to form during the first string.
I adjusted the scope up and settled in on the 200 yard target.
Those 5 shots went into 1. 780. The leading became very previlent, and
chambering a couple of the last 5 became hard. I had to brush out just in
front of the chamber.
I cleaned the rifle, and found leading forward of the chamber in the bore
about 6". I started this time at the 200 yard target.
The first fouler went way the he!! high and a bit to the left. I must have helped it
along some by pulling the shot. It went 3.75" high from the last 4 rounds of
1.57.
Again, the gray streaks started in the muzzle.
I adjusted the scope down to 100 yards, and shot my last 5 rounds.
These 5 shots went into 1.75. Again, chambering became hard, and brushing out
the chamber was necessary.
I cleaned the bore again, and found the same leading as before.
I have not gotten this leading when using my normal 20-1 alloy. I believe that
the boolits were not obturating, and I was getting blow-by.
I will probably continue to use the 20-1 alloy, but it was good to know that even
with the ww alloy, I could still use my load for hunting with good accurate results.
I like the Leatherwood scope real well. I'm still getting used to the 3/4" tube.
When sited for 100 yards, I just raise the elevation adjustment 9.5 moa, or one
full revolution and 1.5 marks to hit on at 200. What could be easier than that?
If I ever get to where I can post picture, I will.
