In the Rock Pit - Crushing Basalt

[sabotloader]

Yesterday was a great morning to get out - so I headed to the Rock Pit with my Western Edition Mountaineer. I wanted to complete my project of getting the rifle sighted in with the new bullet that I had gotten from Bull Shop Dan. In Idaho we are required to use open sights and full bore lead conicals and I was switching from the my normal .503x460 grain Bull Shop to a lighter faster version a .503x350 grain lead conical.

When I got to the rock pit I set up a paper target @ 75 yards and completed the sight in that I was happy and confident with. After that I brought the paper target back in and walked 6 clay pigeons out to the rock wall to complete the shoot. The wall ranges about 100 yards from my portable bench.

I am shooting 110 grains of T7-3f ignited with a #11 Mag cap, I have in the past used a shot card under the bullet to keep the intense heat of the burning T7 from melting the bottom of the lead projectile. But for the last several months I have been using a MMP 50 cal. Sub Base instead of the card for the insulative effect plus adding to the capture of pressure behind the sub base.

It only took 5 shots to complete the paper project - then it was on the to real fun - shooting something that would break. I set six birds on the wall and began a systematic shoot down... The first 6 were so much fun I set up another 4 and worked them down to nothing.

Here is a composite picture of the shoot...

Sabotloader, I missed this one. Good to see that mountaineer in action. How hard are those Bull Shops to load in that gun? Do you have to use a pre-starter or will your ramrod get it done?

The .503 Bull Shop is a "Slip Fit" conical for me and all od my Knights. I just set them in the bore and with thumb pressure or pal pressure push them down through the crown and then the regular ram rod finishes the job.

Bull Shop Dan has the ability to size these to fit most any rifle once you know your bore size.

This is a little better picture of the 460 - looks just like a No-Excuse - same mold but Dan can size it to fit your rifle..

Mike what load were you using for the 460 gr?
I like the sub base idea and want to give it a try.

I am using 90 grains of T7-3F, most would probably tell you I am running them up the barrel with to much velocity with 90 grains - but I am getting the best accuracy there. I know they work at a 179 yards on elk...

OK Thanks I am going to start at 80 and work up. I am ordering some sub bases and see if it helps over the fiber wad.
Thanks again
