Well, I've been scratching my head trying to figure out how to tune the vertical out of my new 6BR build. It's not too noticeable at 100 & 200, but at 300, 400 & 500 it is approaching 2 1/2" of vertical.
It's Panda, Edge stock, 9 twist almost 28" long, 12-42 Nightforce, just one ounce under 13.5 lbs. with all the weight I can pack into the butt end of the stock.
Admittedly, it's muzzle heavy. Might have to cut it off.
I got to messing around with my rifle/rest/bag setup in my shop this evening with it sitting on the bench top.
With the forend touching the front stop where I normally shoot (about 1 1/2" in front of the bag) I tested how much force it would take with my fingertip to lift the butt end off of the rear bag. Not too much.
I then slid the rifle back until the forend was just even with the front edge of the front bag. There was a noticeable difference just using my fingertip under the end of the buttstock.
I'll point out that my 30BR shoots like crazy with the front stop in the forward position mentioned above. It is not nearly as muzzle heavy though. In fact the 30 shoots so good that I can place the cutting edge of a hatchet facing me at 27 yards and split a 115 Euber and score 2 wipeouts at the same time on an IBS 100 yard target placed at 100 yds.
Well, back to the 6.
I thought I would get a bit more scientific and get the trigger pull gage out.
I caught the hook of the gage in the hex of the brass weight plug in the end of the buttstock.
With the stock forend back out at the position about 1 1/2" in front of the front edge of the bag, it took about 1 3/4 lbs to lift the rear end of the buttstock off of the rear bag.
With the front edge of the stock at the front edge of the front bag it took about 2 1/8 lbs to lift the buttstock off of the rear bag.
By moving the rifle rearward 1 1/2", I increased the weight toward the rear of the rifle by 3/8 lb. I was honestly amazed by this. Never thought this small amount of movement would mean so much.
Will this help in solving my vertical problems??????????????????????????
I'll know when I get to shoot 500 yds, conditions permitting.
Just thought you might find this as interesting as I did.
By the way, my 30 does shoot like crazy but I was lying about the hatchet thing.
