BR: Are you asking me?

If so, I don't recall ever saying they did not expand and hold together.I never even mentioned them; I discussed Partitions,not CoreLokts.Someone else mentioned corelokts after I posted on the Partitions

But as long as we're on the topic,my understanding is that Remington, quite a few years back, turned the spitzer-type CoreLokt into nothing more than a standard C&C bullet to cut costs.Johnnie B and others have mentioned this on here many times...IIRC there were expceptions and the round nose was one of them,and they are built the same as they always were. Apparently not all CoreLokts are the same.....




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
