Frequent range trips.
If I load up say three loads for data, for a specific rifle of mine, I don't wait, I go to the range that weekend and see how it works,, if it don't like the results, I discard the data and try something different like OALs or powder.
To this day I have never had the desire to weigh my brass, and in my 7 mm rem mag loads I use two different brands of brass, Hornady and Winchester. The diferences that "Benchrest shooters" see in their accuracy due to varying weights in their brass, doesn't really affect what I'm looking for in a hunting load,, yes I'm looking for top-notch accracy but not necessarily one- hole at 500 yds accuracy..(although that would be nice)
Thanks for coming!
