Hello
The 45 AUTO reviews that I did were shot with a Walther PPQ 45 with a polygonal 4**¼ inch barrel.

First I do forensic exam of the ammunition. Next I shoot a group while chronographing. Targets were were set at 15 yards. Chronograph is a Oehler 35P

Then one round of each ammunition brand is shot into a 55 gallon plastic barrel of water. The bullet is then recovered, photographed and then measured for expansion. In cases where the bullet fragments and loses its jacket, a weight is taken with all the recovered material and also a weight taken with just the lead core.
Here is the link to all the photos of the review;

45acp SPEER G2 230gr JHP +P — Postimages

Data Sheet



This is the second generation Gold Dot. A polymer material is stuffed in the hollow cavity in an attempt to solve the plugging up of the hollow cavity with clothing issue.
As expected, expansion in water was excellent with good weight retention. Very nice Standard Deviation was recorded.
This product used small pistol primers.
I'll start including price/round in reviews.
While shopping around I found quite a variation in pricing. Those on-line stores that carried this product, the cheapest, Cheaper than Dirt, was $1.54 per/rd, and the most expensive was the Speer website at $2.35 per/rd. So, shop around..
