Bullet holes and group shape tell the tale

Sinclair Wrote:O.K., watched the video. In another video it is suggested to stop weighing the charges, measuring cases, etc. is a waste of time. Other steps are more important, what are some of the hordes' views on this.

I would weigh charges when I was using a poor powder measure and longer stick powder. I bought a Harrell measure about 25 years ago and use Varget for most of my competitive loads (non Grendel). Yes, if a guy weighs each charge he will find that even with a Harrell he will have variance. The question is what does it mean for his purposes? We use electronic targets for prone competition now and they will give velocity and SD at the target. Not perfect but a good enough device to make decisions. Throwing charges into the brass with the Harrell measure my SD's at 600 were under 10 fps. I know that somewhere within those sixty or eighty plus rounds that probably six or eight varied more than + - .2 grains with at least three being a half grain more or less than average. After shooting three very good strings prone unsupported with an optic, I sure couldn't tell which ones had what I most certainly believed a half grain more or less than average weight. Shots went to my calls and the SD was fine for my purposes.

I also tried the brass weighing and segregating. Not even the people who do it know for sure if it matters. I think it is an OCD sort of thing unless you use different makes of brass. I wouldn't expect consistent performance if I mixed Lake City 7.62 with Winchester .308 brass.

Use good components of brass and bullet. Find a decent and consistent load of primers and powder. Use a decent powder measure and dies that are of high quality to ensure case and cartridge run out are minimal. And a press that is solid and whose ram is in alignment with the die. Thats why guys like using the Co Ax presses. Die floats a little and self aligns with the brass. No need to measure each charge, particularly if using ball powders. Chances are a decent measure varies less than the average electronic reloading scale.

The part that requires a lot of work if someone wants to be a very good precision rifleman is the actual doing part. The least amount of time spent handloading the better.
