Well today was fruitful to say the least. I did a break in on my nephews gun that went surprisingly well. I shot a 300 yard group with Wildcat 169.5 grain ULD RBBT HPs and the ULD flat base HPs. I will post the pictures of this in another post tomorrow. I have to say I am EXCEEDINGLY happy with the group made with the RBBTs.
The topic of this post is, at the least, perplexing. We shot a ladder test with my brothers .338 win mag and had surprising results. The velocity increased with the increase in powder for the most part but the impact string went up and down. Alot. I was expecting something that resembled the velocity string. I expected the bullet holes to rise and settle then rise and settle. No such luck. In fact the last shot was only an inch and a half higher than the first shot but the extreme high and low shots were over 6 inches apart.
I will post pictures of the actual target and the velocity and shot graph tomorrow (it is too late and I'm too tired to mess with it right now) but I wanted to get all you experienced ladder testers on stand by for this one. I have no idea what is hapening on this one. I actually have a theory. I am wondering if the gun was taking a toll on my brothers shoulder. He said that he was doing fine and he did keep shooting in a group (somewhat) or rather the shots were coming out near each other. They just weren't rising up the paper.
Please keep an eye on this post for the incoming info. I really dont want to shoot this ladder twice if we can put together a satisfactory node from the info gathered.
Thanks guys. /ubbthreads/images/graemlins/wink.gif
