Our 10mm 180 BCSP is a bullet we make in-house. It is a jacketed/bonded lead core. It is designed for hunting and willnot fragment.

I would like to see what happens with the DT 135 grain JHP. I have some recoverred from wet newspaper and there was significant fragmentation.

I really think you are onto something about dellet design. It is interesting to note that the 10mm Silvertip is an old design. Winchester put it out at near full house loading years ago and have never changed it. If bumped up slightly by DT I bet it would hold up much better than a 180 grain Gold DOt designed for 40 S&W.

Look at the 200 gr XTP. It openned up really well, penetrating very deeply. It also I believe was a round desinged for the 10mm. That is the round in my backup mag, simply because I figure having rounds that will work on most 4 legged or through cover might be benificial, especially if I have used up all my 135 grains.

I may have to drop DT an email asking for a Silvertip loading...

I wonder how the Hydrashock would perfom at increased velocity? Too bad I do not believe it is available for reloading. My local Sports Authority is selling them for $4.99 a box of 20 to get rid of them. If I was was comfroatble loading to DT velocities, and I am NOT, I would buy a bunch, pull the bullets, and reload them...

I've seen the 180gr Gold Dot and the 180gr HST pulled out of gellatine having expanded to this size. When the bullet isn't pushed too fast for it's design then the mushroom stays big instead of folding over on itself.
Pushed too fast it's common for the mushroom portion of the bullet to fold over so that the bullet looks like a badmitton birdie, or break off of the bullet shank entirely.

I shoot 180-gr Gold Dots at 1185-fps from my G29. They perform exactly as I think they should. I don't see the point in overdriving a bullet design.



Yeppers, that is over 1.00" expansion and 100% weight retention. That's why I'm not a 10mm speed junkie.

I know this is not a tell all test but when i have fired DT GDs out of my G20 into milk jugs they were small and looked like a badminton birdie. Now the Reeds Silvertips at 1300fps mushroomed out. They looked a lot better. And for anyone who assumes i am badmouthing DT ammo, im not. Just reporting my observations.

At 1300 FPS, it doesn't surprise me at all to see a GD turn inside-out. They are relatively "soft" bullets and work best at medium velocities. Loaded down a touch, and they will expand very widely.

I've seen pretty good expansion out of 155 grain ST bullets at .40 S&W velocities, and rather minimal expansion from XTPs.

I do trust the GDs to expand if cloth is in the way, though. I've had STs and XTPs fail to expand if the hollow point fills with cloth, but never seen that behavior from the GDs. Maybe they act similarly to a "soft point" in such a case?
