Would this be a winner in 10mm? I'm sending a couple of BCSP's for gel testing and will post the video here when he does them. Problem is the BCSP's are Cor-Bon only. These Winchester's can be loaded by one of our suppliers if they would be something people wanted (hold up better to high velocity?).

I like.  I don't understand the JHP/JSP label, though.  Which is it?  According to the image, it's JSP.  Some heavier bullet offerings would be nice, too.  For decades, I used JSP's almost exclusively for high-power hunting handgun rounds.  That is, until CA banned lead bullets for hunting.

Still, they are labeled JHP, but the image is a JSP.  I wouldn't be interested if it is, in fact, a JHP.  I've used these bullets (JSP) in other calibers.  It appears they discontinued the .41.  Bummer.

I like the general premise, but at the end of the day I don't see a gain from what's already available.  Hey, the just my opinion, I could be wrong.  I say run it through some testing and see what we get.

 My order gets here Monday of Cor-Bon BCSP's and I will send some over for Gel testing. I'm hoping to see the pretty Mushroom some like to see without anything funny happening to the bullet. He also has to lengthen his Gel because I think these will hit in the 20-24 inch range of penetration (the BCSP's). If this works okay he said he would work up some loads with the Winchesters since the Cor-Bons were only about 1200 FPS.

Good stuff.  I'll definitly be looking forward to the results.  Though I'm not really betting on anything one way or the other either.  It will be interesting.

Nobody has done it. tnoutdoors9 doesn't have any interest in doing it either so it will be a first. If we can get the block super extended I would like to send a couple of my 220's to him and see how far they travel and do to it. Might need 40" of block for that.
