I was suppose to work a 1/2 day today but the morning was so nice -I voted I not work and go do some more shooting!
What I wanted to do today was to collect velocities and see which of the two bullets fit the Mountaineer the best. So I packed up and headed to the farm. Got setup and placed the chrono about 10' off the muzzle. For some reason I spend way to much time worrying about shooting the chrono than I hitting the target. Now that I am back here I also should have moved the chrono to the target and got some 50 yard velocities... darn me!
Anyway here is the information I was seeking...
I had decided that I was going to load the .502's which seem to fit the greater portion of the newer Knight 50 cal bores than the 5015 might. It was a great match for that bore. I could insert it in the bore and push it down through the crown with the heal of my hand. Those of you that use a short starter it will be a easy to insert it. Even in my tighter Ultra-Lite bore using the .502 and a short starter makes short work of loading. In the tight bores you will be happier if you have some sort of palm saver for your ram-rod.
Another thing I wanted to prove to myself was that the bullet was sealing the gases behind the bullet. So the first three shots were taken seating the bullet on top of 120 grains of T7-2f. They were then shot across the chrono. Then I loaded the same load but used a MMP sub-base. No real difference in velocity but I think the sub-base may have effected the flight of the bullet by sticking in the powder cup of the bullet. Anyway they did not seem as accurate as you can see. Next I loaded the .5015 bullets in the rifle. They were fairly loose easy to load easy to get down but I felt there was enough pressure that they would not come off the powder. The bullet did seem to contain the gas as the velocity remained relatively the same but they were a bit lower on the target.
This is my Mountaineer and yes I like thumbhole stocks
Here is the target with velocities - do not get to critical of the groups - I worry much more about the chronograph than I do - how tight the group is... I know 'cop out'
These are some additional pictures of the shoot activities...
