CHUCKO:
I will have to disagree. The bullet weight, in my opinion, does make a difference.
Example: During military testing of the 30-06 round. Using the marrying system, the 150 grn bullet would only group @ 600 yds, M-i Grand, and the same for the Springfield 1903. The 180 Grn was good to 800 yrds.
The 308 was a similar story. 150 grn good to 600, the 168grn to 1000yds.
Colt H-Bar. The 55gn bullets, opinion, good to 400 yrds. Now I don't remember the bullet weight, however, it was greater than 55grn, won the 600 yrd match at Camp Perry twice. I am positive that the bullet weight was instrumental in that. The 55gr wouldn't make it.

I was able to get it to print on one page and clear up the slides. Opinion. Printing has to be @ "best" setting to contrast the text.
