Any differences between rcbs 201-kt vs the new offering which is the RCBS82047 ? I'm looking for one and people are asking more $$ for he kt version than the new one..

Both molds drop a H&G #68 clone bullet as nearly as I can tell.

Shorter top drive band on the new mold/68 clone.

The 201 had equal bands for the bullet's base and top drive band. The "new" rcbs mold has a larger bullet base band and a smaller top drive band.

IMHO:
Bullts with larger drive bands do better. A link to a custom mold maker that has been putting out the offset bands on the 68 clone for a couple years.

I use/shoot an offset (bigger bottom/base) version of the 68 clone in my 45acp. It's a mold from the mold maker in the link above.


good luck

I believe that the MiHec and other molds with the narrower top driving band are faithful to the original Hensley & Gibbs #68 design.

My RCBS 452-201-KT produced bullets that were slightly more accurate than my H&G #68 mold. It then became the 452-201-SWC, then it became the 45-201-SWC. If they made ANY changes from the KT, I would be very surprised if the bullet was actually any better.

As with any of the mold makers they bounced back and forth with multiple drive band widths.A link to a picture of the original h&g #68 mold.

The link above clearly shows equal drive bands.

I've seen/owned h&g molds that had the equal drive bands and the original offset drive bands.
A link to another popular target bullet that h&g made molds for, the h&g #130. It has a smaller nose then the h&g #68 and weighed 185gr. It also has the large bullet base and the smaller drive band.

H&G also made a "heavy" version of their h&g #68, these are extremely hard to find. Instead of making equal drive bands for more weight h&g made an even longer bullet base to increase the weight og the 68S (heavy).

A link to a search using bing, it has pictures of the h&g #68 bullet with the equal bands and a bb.

So when the OP asked about the difference in the 2 molds the answer is:
The 201 has equal drive bands & rcbs's new mold has a large bullet base and a smaller top drive band.

I don't know if there is any difference;all I know is that I got one KT from the mid '80s and it still casts extremely good bullets and shoots great!
