I had failures to extract problems with Titegroup powder (2-3 per a box). So I got an lb of Blue Dot powder to see if it will be any different (I wanted Power Pistol but the local gun store it out of stock). I used the same 138gr RN copper plated bullet and also had some 147gr FP copper plated as well.
I was going to use 6.1gr of BlueDot, powder dencity must be off because my Lee Auto disk charged only 5.5gr
-------
So I shot 100 rounds of reloads though the gun; 50 with 138gr and 50 with 147gr same charge for both.
First box (138gr): had about 2 Failures to Extract, AND about 4 or 5 Failures to feed. 8-O (never had any before) The OAL was 1.14in -- longer than the OAL of the Titegroup loads (1.10in)
Second box (147gr): I think I only had 2 Failures to feed, don’t remember if I had any Failures to Extract but wouldn’t be more than 1. These loads had OAL of 1.15in.
The first box might have been a little light; I had round (same as powder flakes) black ash-like residue on my arms which might’ve been unburned powder. I think it was happening less with 147gr loads but not sure. This is my first time using Blue Dot, so not sure if this is normal or not.
I also had 3 failure to go into battery, at lest I noticed 3 ; at my range when I shoot I can see the back of the gun in silhouette and can’t tell if the slide is in or out of battery unless I lower the gun and take a better look at it. Which made me wonder if it happen more than 3 times and I just 'shot though it'… :?
Next time I go to the range I will do a test with primed cases to see if the gun fires out of battery. The last thing I need is worrying about a KB. :?
btw the gun has about 550 rounds though it right now.
