Mine squashed the brass at first, but I was having a little problem with the extractor being overly tight. It was hanging on to the brass and causing intermittant failure to return to battery. When I loosened the extractor a little, both probs went away and it barely dings the brass now. I think that most folks will tell you that its pretty gentle on brass.
Disturbed, ive shot about 300 rounds of wolf throught my mil spec, no problems what so ever, but remember wolf ammo is steel cased not brass so dont but it to reload it, also its laquered to prevent rust. for cheap ammo its great...Waterbull
If the WW2 model dents brass so badly that you can't reload it, I want to shoot Wolff (cheap crap) through it. I have two Series 1 Kimbers that I would never shoot Wolff ammo through but the WW2 would be a "beater" so to speak and I want to shoot cheap crap through it if it beats the **** out of brass.
i have a ruined AR15 barrel from the lacquered wolff ammo. it glazed the chamber and now the only thing it will fire is wolff ammo till i find a new barrel. im never using that stuff in a firearm again.
Most non-premium HPs don't always expand (in fact many don't expand much at all), so you'd really be getting ball performance out of them.
Premium HPs (Golden Sabre, HydraShok, SXT, Gold Dot, etc) were engineered to open at the lower velocities of a .45 ACP (I know Federal spent a LOT of money making the 230-gr. HydraShok work). But still they don't always open up.
The other expanding option might be Federal's EFMJ (Expanding Full Metal Jacket) but I have no data on their availability or effectiveness.
Bottom line: HPs don't always feed in 1911s without modification. Those that do, don't always open up. So, if hollowpoints feed in your gun, worst case scenario is they don't open and you get the same performance as ball ammo. If they open up, they do big time damage.
Ball ammo never opens up, but the vast majority of 1911s will feed, fire and extract with no hiccups. And it does make a .452" hole, which is nothing to sneeze at.
Personally, my 1911s have fed 230-gr. HydraShoks and Golden Sabres well, but I have had failures with them (all failures to feed), maybe 3 or 4 out of 100. I've never had a problem with FMJ ammo in my Springers or Colt, 100% reliability with both brands of gun. So, that's what I carry. Either Federal American Eagle, or Winchester White Box or PMC, all seem equally high quality. That being said, the WWII is a fine weapon, so it's really going to be up to you and your comfort level. Of course for authenticity, you'd have to carry ball.
One last thing, I did have one 1911 that choked on ball. It was a full-size Llama. Would jam 2 or 3 times PER MAGAZINE with ball, and was a single shot with HPs. Didn't matter what magazines I used. Needless to say, it went on the chopping block real quick.
Ummm, what, you think there's not 230 grain HP available?
After receiving your reply I did a little search and you are right, they are available but extremely hard to find pre-loaded unless you get the high performance stuff, and a non-hand loader is not going to pay big money for a day just cutting paper. Most of the sporting good / gun shops in my area stock 185 JHP or 230 FMJ. Those are your only options.
