This past weekend I finally found time to do some shooting and sight in the scope I just mounted on my Black Diamond. Before I went I discovered I only had about7 T/C 250 grain Shockwave's left so I headed to WalMart. Guess What Sold Out. They were nearly out of everything. I found a package of powerbelt 295 grain bullets. I figured I could get the scope close with these then fire 1 or 2 rounds of Shockwaves and be ready to go this Saturday when season opens...............Wrong

I had the gun shooting good at 25 then moved out to 100yds and the gun was shooting about 5"low. Made my adjustments and was hitting within an 1" either side of the Bullseye. Close enough for this blind man :-) I then fired two rounds of the shockwaves and never hit the target. I was just using a 8 1/2 x 11 page printed from mytargets.com. I am not a physics major but I would assume I was shooting way high or am I wrong. Does 45 grains of bullet weight make that much difference?

I have since went out of town and bought another box of Shockwaves to use. What is the best way to site this gun in. Start back over at 25yds with the Shcokwaves and then move out? Thanks for the input

I would get a VERY LARGE PIECE OF CARDBOARD and put a small bulls eye dead center in it. Then start at 25 yards with Shockwaves. If your Black Diamond XR is like mine, use 100 grains of powder to get the scope close.

Shoot your first three shot group at that distance and if they group tight, which they should, then make an adjustment to the scope. Be sure and swab between each shot you take. When you shoot your second group be sure and do an extra good job of swabbing the bore. Keep swabbing and shooting until your cutting the bulls eye out at 25 yards.

Then move it back to 100 yards. Mine then was hitting just at the bottom of the bull with the same load. At this distance I also started working the load up. I got it up to 110 grains of Goex 2f and was happy with that.

I also had real good luck shooting 200 grain Shockwaves and 375 grain Buffalo Bullet SSB's. All of them shot real well out of the Diamond. I intend to shoot the 200 grain Shockwaves this deer season and see how they do in the large hay field....

Good luck with the rifle.

Thanks Cayugad, I just found the difference in the two bullets pretty amazing. I figured I would be about 3 or 4" high with the shcokwaves but to completely be off the chart surprized me.

One projectile is saboted , the other is not , In my tc powerbelts hit anywhere from 6-12 inches higher than saboted bullets .

"I have since went out of town and bought another box of Shockwaves to use. What is the best way to site this gun in. Start back over at 25yds with the Shcokwaves and then move out? Thanks for the input".

Yes, start back at 25 with the Shockwaves. You'd be surprised at how much difference in point of impact can be attributed to seemingly small bullet weight changes in large-bore rifles. I learned this when working with the .45/70.....
