Today I shot some H&G #68 (Mimek) from my S&W Model 625 .45ACP.
I have shot many thousands of rounds with RN boolits through this revolver and I've used a lot of the H&G 68 in my 1911, but never the #68 in the 625 before.
What causes this?

The load was 4.1gn of Bullseye with OAL 1.250" and Speer .45 ACP cases.
Alloy was water quenched WW and they were sized to .453".
Was there a staple under the paper right there? That's the only thing I can think of.
Are you sure you weren't shooting Cherry Bombs!! Very unusual, never seen anything like that.
Looks like nothing but air behind the target? If so that rules out any foreign object behind target, could it be lube spinning off boolit? Dennis
Total speculation here , a ruff land or crown pulling some alloy from the boolit & as the base exits it`s blown out to the side .
It may take very close inspection to find it .
I like Dennis` theory better , what lube do ya use ???
What distance ???
I have`nt had coffee yet !!!
You could try shooting a few of the same bullets sized but not lubed then a few lubed ones to see if it is a inflight lube seperation problem. What lube are you using?
Looks like a GC hole. Do they have checks? Are they loose on the base?
Maybe the bullets are doing that in protest of them being in the white?:kidding:
I doubt it is lube related. Of it was then I would expect to also see a few bits or globs of lube on the paper.
Not a GC bullet so that is out.
Interesting. Very interesting.
Could it be caused by staples from old targets behind the new one?
Does it do it all the time or just those two?
Im clueless and have no knowledge on what could be causing it...but...
Is there a possibility that the boolit is grabbing lead out of the grooves?
Your bullets are hitting the paper too slowly and the paper is tearing. Just kidding. My first thought would be that it's the paper just tearing but it definitely looks impact related upon closer inspection.
What you have are very fertile loads.
three of your four tail fins fell off your rocket propelled boolits [smilie=l:
Obviously Love Bugs hitching a ride....
What lube? Maybe a string of lube spun off the bullet but not disconnected. I have seen
lube chunks on the paper.
Definitely odd.

Thanks for your replies, guys. Lots of humour as well, it is nice to be among such a friendly crowd! :)
* There were no gas checks involved.
* Behind the target is just empty air, the holes were no where near the target stand.
* No staples at all, as you can see the center targets are slit and slides into the bigger target. * Distance was 15 yards, I was not hitting paper on 25 yards due to the Red Dot being newly mounted, so I had to go closer to find somewhere to adjust from.
* Lube is Carnauba Red.
After sighting in, this was next shot at 25 meters (27 yards), using the same gun and load with 6 shots:

I have two theories of my own, both pretty similar.
* It could be that the oversize boolit is shaved when seating and that the small excess of lead sticks and acts as a tail.
* Or it could be that the well fitting boolit pushes off and sticks to some of the lead I had trouble getting out from the barrel from when shooting undersize boolits last week. They were .4515" and didn't like my .4525" throats.
this is my vote...expecially after your next bunch of shots show no "tails".Quote:

Is it all the holes, or is it random? If it's all shots I don't think it would pull lead the same way every time. If it was something attached to the boolit, it should be a radial tear from the projectile spinning, that looks like it went in straight. Try it with the target on a peice of backing to see if it may just be the paper tearing.
Hard lube, spinning out of the lube groove.
Lost two feathers from the fletching! [smilie=l:
