New here, need some help
Slow night at work, so I've been trolling the older messages in the off times. Yeeaowza! What a trove of knowledge! Think I'll hang around a bit ;)
I've got a situation here that is just plumb driving me up a wall trying to make sense of it.
My neighbor has a new Howa M1500 heavy barrel gun w/ a laminated target stock, wearing a 6-24x Sightron scope. I donated the .308 Win brass, some Nosler 150gr Partitions, and the RCBS 'Reloader Special' dies (i.e. the cheap ones w/o a box) from an aborted project I had a while back. He's loaded up some (IIRC) Nosler 125gr BTs and started shooting them.
The first weird thing is that after getting the gun to print on target where he wanted (~1.5-2.0" high)at 100 yds, he began shooting at 200. The bullet impact was actually *higher* (~2.0-3.0")at 200 than at 100! Then he shot at 300, and the bullets did drop, but not nearly what I would think they should, maybe only a couple inches if that, from point of aim. This is a bit weird by everything I've ever learned about 'zeroing' rifles. If the thing is a little hight at 100, it should drop to be 'on' at 200, and some amount low, depending on load, at 300. I've discussed this w/ him and a few other local shooters, and nobody seemed to really have any good idea why it did this, other than 'it must have still been rising'. I've seen this a little when a gun was zeroed for some ungodly range way the heck and gone out there, but not something simple like a 200yd zero. Hopefully we will be able to put this gun (as well as my 40X in .220 Swift) into service this spring on the area ground hogs. I'd just like to know why the gun doesn't shoot quite the way I'd expected it to ;)
