Why is it not done ?
Last week I cast some 358 SWC 163 gr. with a gas check type base.
I have been experimenting with the 35 cal Checkmaker I bought from Pat.
I have been using pop can aluminum.
I put some checks on these boolits
then sized and lubed them with my Lyman 45,
the checks visually look like they were sized/crimped onto the base.
I loaded them into some 357 Mag cases with 11.0 gr. AA#7
no problems, the checks stayed in place throughout the whole process.
They shot fine, accuracy is what I'd expect with my ability.
I ask again, Why is it not done ?
