You guys may want to try annealing the tips, it appears to work very well, and would be a more cost effective way of getting the desired results.
The serrated jackets still haven't shown up but once they do I'll whip up a batch & send em back for your pleasures

Hi Marshal......Do you know what the tip thickness is after you draw down the .308's to .264"?. Annealing definitely softens them up. I quit bonding some of my bullets for that reason when I didn't want them softer.....Rich

Rich,
The thickness doesn't change much if any, the length is gained from reducing the base, but since I don't have any on hand right now I cant give a 100% honest answer.
I kinda think that since the lead is down .300+- annealing would be an easy way to go.... maybe

Hmmmmm.......

Time to fire up the torch and get some more jugs!

Re: 160gr Matrix

I forgot about the Corbin jackets being a straight wall (.015") for about 3/8" before they taper sharply to .026". Most jackets taper immediately so that would explain being thinner further down the ogive (because of what Marshal explained).......Rich

Re: 160gr Matrix

I got the bullets from Marshal that I serrated and I am afraid this is not a viable option as far too many collapse (fold) during the point forming process. Marshal has been extremely cooperative and helpful which I greatly appreciate. At this point, I would agree with the annealing procedure. As a bullet maker myself, I can tell you that Marshal makes a good bullet, especially at the price! Any additional steps, such as tipping, trimming jacket length, bonding, etc., will greatly add to the cost. One other thing you might try is drilling out the tips with an approx. .030" bit if you want a little more expansion........Rich

Re: 160gr Matrix

I decided to run a quick test on the 160's today. I only fired two rounds thru my plastic barrel filled with H20, but the results looked promising. They expanded at least 200'/sec. lower than the 215 hybrids. With a very small test, it appears in this media that expansion takes place between 1700-1800'. I will probably run some more when I get time........Rich160gr Matrix-dscf0802.jpg
I found a couple pieces of lead with the 1811' but lost them in the shuffle

Rich,
That is a bit lower impact velocity than I have tried.
I shot some annealed ones that had 18" of penetration as compared to 24" without at 1900fps with the bullet shedding a bit of the jacket , the rear half weighing 80gr.
