What velocity are you getting from the "Lehigh", hunting results? Case bulges in 10mm loadings can be a quirk of not fully supported chambers of some 1911's and stock Glock barrels, or maybe they're telling you something you might want to pay attention to....... pictures when you can10mm is an awesome round. I have a Les Bear Hunter Longslide. I hunt with Lehigh Defense 150 g extreme hunter loaded over power pistol.
I use 5 Redding dies for this caliber. I have a die to take care of the lower case bulges, full length titanium sizing die, case mouth expander, seater and I taper crimp in a separate step. I use a LE Wilson pistol max gage to check every round.
Just new to the 6.8 I haven’t worked up anything for it yet. The 120g SST’s shoot sub MOA out of my rifle. That’s as far as I’ve gotten so far.
Where did you purchase the bullet/only? tksI’m not sure of the velocities. I just copied an Underwood load after pulling down a few rounds. The bulges are not really noticeable to me. Not like a smiley face or unsupported case. The only way I can tell is that they don’t fit into my Wilson pistol max gage. I’m using nickel plated Starline brass. I called Redding and asked why the full sizing die didn’t work and they told me about the push through die. I bought it and it worked. My first 10mm was a SA and then I bought this long slide Les Baer. The bulges were only in the SA not the Les Baer.
There aren’t any signs of over pressure at all in either pistol.
