[QUOTE="Deleted member 107796, post: 1544954"] Sorry, but I don't agree fully with either of these posts. A flat base, heavy shanked lead core bullet will require the same force to insert into a case as any all copper, boattailed bullet, especially if the case is properly chamfered (I like to keep this interior chamfer light, as I reload WSMs with their short throat). It's never been an issue with a NP or Swift A frame or a Hornady GMX, Barnes or other. If there is a fit issue, a full length sizing should fix any issue of insertion force. Second, there is little chance that all copper bullet developers will not test to max CUP fully with real statistical data, to show than any increase in pressure is not significant. This, along with quite a bit of of user data, would make me conclude that the increase can't be characterized as, " a lot more." [/QUOTE]
