Below is a pic from my last outing to the local range (yesterday). I'm still experimenting trying to find the best load for my Remington 300 WM. As you can see, I have 4 pretty good groups and one with a little bit of a flier.
The last time I shot this rifle for groups at 100yds it (and I) seemed to be a pretty consistent 1" grouper. The consistent pattern looked very much like the lower right group in the target below (two very close with one outlier). I probably shot 5 groups that followed that pattern in one form or another - some a little under 1" some a little over 1".
I have a couple questions...
The only thing (that I'm aware of) that changed from my 1" session and this session that is closer to 1/2" is that I changed the scope from an older 3-9x Leupold VX-II to a new Leupold VX-3 4.5-14x LR. I don't think there is anything wrong with the VX-II, so the only thing I can think of is that the 14x sight picture helped me hold tighter. It doesn't feel like that should be the case, however, as 9x at 100yds should be plenty for grouping.
Has anyone experienced a change like this just from a scope?
I'm feeling a bit premature in saying that I and my rifle are shooting 1/2" 3-shot groups, but of course that is what I want to say
I plan to go out again and see what happens, but I'm looking for any insight or thoughts on what I might be missing that could cause a change like this.
In the mean time I'll be loading up some different bullets and powder combinations to see where that gets me. I have some 180gr Accubonds and H4831SC powder to throw in the mix. My goal for this rifle is to be able to turn in targets like the one below on a consistent basis (close to 1/2" average).
Thanks for any thoughts and insights.
