I did this as well as a few other "45 Caliber Kings" in a bunker thread that was supposed to be a good indication of penetration and expansion using the same test media (wet newspaper) to be fired from the same distance of 7yards.
Would have been a great information resource but only a few who committed to the test actually did it.
Oh well it was a great idea.
Here were my results cut and pasted from the other thread with Federal HST 230gr fired into wet newspaper at 7yds----------------
Fed 230gr HST +P @7yd
Kimber SIS Custom 5"
Wanted to get a decent camera before I posted, didn't get one yet so these will have to do.
Fired two shots originally and measured the depth, was surprised by the penetration(or lack of) First shot struck near the paracord I'd wrapped the paper in. The paper was slanted in near the impact point and I think that accounts for the uneven mushroom since there was no sign of any bullets tumbling. Second shot hit paper square.
Shot 1 5 1/4"________ .919" ______183.4 gr retained weight
Shot 2 5 1/2"_________.940"______231.7gr
Thought maybe the paper being bound tight accounted for less penetration than expected. So I cut paracord and shook out the sections of paper and restacked. Fired one more shot and the results were consistent.
Shot 3 5 1/2"________.925"_______230.4gr
Sitting on a quarter
So thats what I got.
I also took the opportunity (a little OT)to fire a few shots from my 16" barreled AR just to see what it would do since I had a discussion in another thread about lack of penetration with .223
I fired 3shots with handloaded 60gr Nosler Ballistic Tips.
They penetrated about an inch at approx caliber size then the expansion became violent and ended in complete fragmentation with total penetration of 7", 7", and 7 1/4"
Not much left to see other than a few pieces of jacket,plastic and the bullets bases. But it did surprise me that these 60gr varmint bullets out penetrated the 230gr HST's.
