Very interesting John.
I just loaded up 30 rounds of .223 with some very old Hornady 55 grain SX bullets with a max load of W748. The SXs have been kicking around for 25 or 30 years. I used them in my .22-250 with good results, but I sold the .22-250 over 20 years ago.
Fired five shots at about 100 yards with my Savage with a 1 in 9 twist to see if they were close to the same POI as the Speers I loaded with the same charge.
When I went over to check the target there were three holes. It looked like one was enlarged enough to be two together, but there's no way three could have gone through the same hole!
I think I'll break out the Hornady bullet puller and replace the SXs with some 50 grain V-Maxes.
Maybe I'll use the SXs with some Blue Dot at a lower velocity.
