50 yard bench rest 15? slight wind 1mph, overcast, snowing
White Bison .504 Simmons Pro Diamond 4x32mm scope
500 gr Bull Shop Conical .504 diameter sized in Lee sizer
90 gr of Pyrodex RS & Triple Seven 2f
80 gr of Pyrodex RS & Triple Seven
Due to the warm weather and lack of wind.. I figured it would not be too bad shooting today. Granted it was snowing pretty good. I also loaded all the powder charges in Lane Tubes for easy loading. I had ran a box of Bull Shop conicals in 500 grain through my Lee Sizer the other day, because the Bison really likes that diameter conical. So I figured I was all set.
90 grains of Triple Seven 2f was used there. I wanted to see if the Montana X-treme bore conditioner would hold that first shot. So I dry patched the barrel without Windex or alcohol and popped one #11 cap to check for fire channel, before I started the test. I did not swab during the four shots. I also never noticed a crud ring of any kind when loading the other shots. I was more then happy with that group. Especially since I normally shoot 80 grains of Triple Seven. 90 grains would be a load good enough for about anything IMO.
I laid a clean patch on my tongue to just get a little moisture on the patch (since my cleaning solution spray nozzles tend to freeze closed in this weather) and went to check the first four shot group. I then swabbed the barrel with a very lightly moistened spit patch. There was no crud ring from the Triple Seven. I then shot this three shot group with 90 grains of Pyrodex RS. I would have shot more but I was sure I saw good old Murphy hiding in the woods and did not want to blow that group.
I then swabbed the barrel again with the same spit patch and shot off about fifteen more rounds into various targets. I actually swabbed one more time before the patch came apart.
During our cold snap I had made colored ice chunks. I used small plastic containers and set them out in the -30 degree weather. So I was setting them up on the back stop and splattering them all over the woods. It was a lot more fun then paper punching.
So far this Montana X-treme bore conditioner seems to hold the first shot into the group. Also swabbing is very easy. Whether this bore treatment is the cause is hard to say in the Bison's case because this rifle really is a gentleman on the range about swabbing, and shooting dirty. Also these Weaver quick release rings came back to true zero real well. The weaver are a lot cheaper then the Warne.
The rifle cleaned easy (as normal) and I treated the bore with the Montana X-treme again. So we will see how it does at the next range session.
