Title: 200g polymer coated lead "Blue bullet"
Post by: gadabout on August 04 2021 08:00:52 AM MDT
I am loading using universal as I had good luck in 9mm with it. Hods site has it at 6.2 max so I will load 6.0. I thought I had loaded a few of these in Power Pistol but it must have been 40 cal. I have done a lot of 155 and 165 but not the blue bullet so far. Any input would be nice Thanks  Craig

Well I loaded 56 as it's all the brass I could find. We will see how it shoots.  Craig

Craig, I haven't played with Universal powder at all.  It is said to be a good shotgun powder.  My Hodgdon book shows 200 grain jacketed FMJ using 5.9 grains @ 1015 fps

Hey Wade I am running low on power pistol so was trying universal in some blue bullet 9mm and it was very good so I am trying it in 10mm as I am out of small primers but had lots of large pistol primers. I will run out of universal sooner or later and will think real hard if I need anymore. Thanks for the input.  Craig

The 5.9 grains was the highest load for a 10mm 200 grain jacketed FMJ, But this was what you saw on the web page.  This wasn't in my manual, so the have added newer data.

Just got back from the range and shot the 10mm blue. It appears I had a problem withe the polymer rubbing off onto the case and some would not chamber. I will look at all those rounds again. When it loaded it shot great as I was shooting the Kimber target II and the Tanfoliga witness. Only shot maybe 12 rounds but found no brass and I looked real hard.  Craig

OK found the COL set a little long so I adjusted that and checked the taper crimp die and it was fine. Ran all the rounds through again and everything seemed fine and I checked a few rounds and they chambered right up. The residual polymer I found on the cases seemed not a problem as most flaked off after the taper crimp. I will shoot when I can.  Craig

I've found with coated bullets you need to flare the case a bit more, otherwise you end up scraping off the coating.  Seems to be worse if you're seating and crimping in one operation.  Later.

This.  Plus, seat and crimp in separate steps.

That's the way I do it. Seat first then on to the taper crimp die.  I do also agree with the flare comment. Craig
