Today I wanted to see how the Scorpion Funnel Nose 260 grain bullets shot out of my stainless steel, 1-28 twist, .50 caliber GMB. The rifle is percussion. I used Winchester Magnum #11 caps. And Goex 2f black powder. The rifle has a Simmons Pro Sport ($19.95 I believe it was) 4x32mm scope on it.
Since the target could be seen at 100 yards, I decided that was good. To save some walking I even got out my spotting scope today.
I wanted to test the bullet with different powder charge. My shooting card said the rifle likes between 85-110 grains. So I started at 100 grains.
Believe this or not.. that cross hairs on this cheap scope almost cover that 2" circle. Just a small amount of red could be seen around the hairs. And I noticed it shot to the right a little bit. But for that scope and that distance, I was not all that unhappy. I just can't shoot these 1 and 1-1/2 in groups like some of you. But I do my best.
I then knocked the charge down to 90 grains of powder. It should be noted I was swabbing between shots with MAP.
I was now down to a one inch dot. When you set the cross hair on it.. you can not see it. You know your on it I guess because you can no longer see it. 90 grains did pretty good.
So I kicked the charge up to 110 grains of powder.
If that one had not been a flier, that was doing well. I could tell that wearing only a T shirt, sleeveless at that, and shooting, even with the heavy barrel I could feel that recoil, but it was not too bad. And the accuracy was pretty good too.
So I kicked it up to 120 grains of Goex 2f.
While I could have shot more with this powder charge.. there was no need. I did not need that much of a charge to hunt deer. I think the 100 grains will do just fine.
I then set up two old grapefruits from the back refrigerator and smoked them at 100 yards with 100 grains. I aimed 8 o'clock on them and that little funnel nose just made them explode. Pretty cool.
For a deer bullet I suspect this will do me just fine. As for the scope on this rifle, that too will work, but I might just put a real expensive scope on this stainless steel barrel to see what the rifle can really do.
