Great Alaska bear protection round. The Syntech coating makes this a great hard cast round for the Glock 20/40, especially if you've kept the original polygonal rifled barrel. The Syntech coating, in conjunction with the nickel case and sealed primer--see picture, assures it will be ready even after severe weather or a dunking. It groups well, is easy to shoot, and you can see by the post-shot primer picture (bottom), there is no sign of over pressure--a concern with the chamber on the Glock. I did want to mention that this uses a small pistol primer, so you will have to sort these out of any ammo with large pistol primers you plan to reload.
