I had the urge to run a few through my gen4 G27 today. I wanted to try a good 200gr hardcast load, and try a few using Blue Dot, a powder I have several pounds of but never have messed with it much. Humid out and around 75 degrees.
Glock 27 Gen4 (stock)
200gr Beartooth WFNGC, 8.4gr VV 3N38 @ 1.130": 1,032 fps (4 fps ES!!)
180gr MG JHP, 8.9gr Blue Dot @ 1.120": 1,050 fps (3 fps ES!!)
180gr MG JHP, 9.3gr Blue Dot @ 1.120": 1,097 fps (16 fps ES, 5% over book)
Now these probably aren't what you would load up if you're looking for easy recoil and super fast follow up shots, but they do pack a punch since remember, these are coming from a 3.5" barrel.
Brass had some swelling, but even factory ammo had it so I'm not concerned, just the typical stuff.
