I have read about some people that want to make the most accurate hand loads measure thier bullets.
How many of you do that? I tried it to see how it would turn out. I purchased a box of 100 Sierra .277 135 gr. SMK and I measured them using a comparitor on the ogive. This is how it turned out:

0.639 = 18
0.636 = 13
0.635 = 15
0.634 = 64
__________
total of 100

Do you think the difference in lenght would really make a difference in grouping out to say 400 yds?
Do you think this is a big waste of time? I have never done this before and am wanting to get the best results.

Thanks,
Mike

I did learn there is a learning curve using one....
The Hornady SST seem to be more consistant. I will try them next!

I would think that a micrometer or calipers would be more accurate. The comparator gives you only a visual measurement, right?

Someday I want to run a test (couple thousand rounds worth) where I start from scratch and see what does and doesn't make a difference. I keep reading about weighing cases, but then the shooter doesn't weigh bullets or primers. Then there's the uniforming the flash hole, and neck turning, and case sorting, and.... and I wonder what is actually worth the time and what is common knowledge because we've always done it that way?

So, ranting done, I like Sunny's answer. Now that you've done it, go see if it makes a difference and tell us the results.

I wonder the same thing, let us know how it turns out. Enquiring minds want to know. Smile
