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...

good report. And good shooting. Those are some impressive numbers there.

Awwwwww comeon Sabot, watching a chrony blow up is FUN Especially from a 220 grain round nose from a .300WM. Just don't ask me how I know that

Looks like the sabotless might be well on its way to becoming a reality.
Now if you could find a way to mask the sound of loading 😀 That fingernail on the chalkboard sound is what gets me . Sabotless might be a really good thing for all the pac west states and colorado , etc where full bore conicals are required , at least it would provide a better option then is currently available. Although unlike you i still like big lead but I wont hold that against you 😀😀

I would really like to pass on that opportunity!!

You know with the very thin gas rings he created it really is not that bad. I do not know how was able to do that portion of the bullet. But, once through the crown there is really not much bad sounds especially if it fits correctly.


It really is not that I dislike - Lead conicals - it is - ya it is I really do not want to use lead unless I have to and here I have to.
