Tom,
I strongly suspect the Hornady .30 180's you and your dad had trouble with were before Interlock days, but dunno. I know the first Hornady bullets I handloaded were 150-grain .270's in the mid-1970's, and they were pre-Interlock. Don't recall exactly when the Interlock ring was added (which helped considerably as far as bullets staying together) but believe it was sometime in the early 1980's.
You could very well be right. This would have been mid to late 70s maybe up to '82. Maybe a year or two more using what we had on hand. I shot Speer flat bases when I had any say in the purchase, never had any problems with them. When I got out of college and started buying my own, I "discovered" Nosler, first with solid bases, then partitions.
Sounds like it might be worth another try .. now that I have some understanding of WHY it's worth another try.
Thanks much!
Tom
