I've been a Interlock fan ever since Remington stopped selling Core Lokts to handloaders, maybe before that too. I try to keep interlocks on hand, but I shoot them into paper quite a bit.
I have quite a few partitions in 24, 25, 27, 28, 30, & 37. I don't need partitions in 35 and the interlocks work fine. I probably could let the 37's go to someone who needs them.
In the 60's I owned a 264 and the only decent big game bullet in my opinion was the partition, but the cost was too much for me. Now, I own no 6.5's or 338's and I can live with that
I probably wouldn't need to buy more, though every now and then I NEED a certain bullet weight in a caliber.

I prefer classic.
