The primer you pictured is not showing any pressure signs. Looks normal and happy to me.
I'm using 19.2g of 2400 w/240xtp and the load looks compressed but I'm using Hornady's data. I also load 19.2g of 2400 w/240g Sierra JHP's, which seats deeper than the 240 XTP. I'm using data from Sierra's book I use 19.2g of 2400 with Miester 240g lead bullets. I'm using data from the Lyman Cast Bullet Handbook. All of these loads look like they are compressing. None are showing pressure signs. All of the velocities are as published using the LabRadar. All three loads are from ladder testing and all are the most accurate of the test. I guess my SBH just likes 19.2g of 2400. I'm loading for a 10.5" Super Blackhawk |

It can at times under the right conditions be hard to ignite...Mag primers ensure consistent ignition, and consistent velocities with this powder... Mag primers are not necessarily "tougher", but they do have a greater flame front that most term 'hotter'... |

I just finished loading (and shooting a bunch of) the Hornady 180 XTP's. 29 grains of H110 is a fine load.....On the low end of the H110 data but that's just fine with that powder. Your primers look great. Load on with (careful) confidence.....I've loaded a bunch of these over the years with no problems at all.

This is a pretty good read on Primers and Pressure you may want to take a look at. I always found these Primer Flash Test Photos to be pretty neat to look at. Ron |

The reason they might list H110 for a 200 and heavier and not a 180 or lower is no doubt because H110 is a slow burning powder. I used the Hodgdon load data instead which lists 29 as a starting load, and 31.5 grains as a max load. Since I don't ever just go to a maximum load, I decided that I'd try 30 grains to start. That is well below the maximum listed by Hodgdon. In hindsight, I should have used the minimum load. Perhaps I wouldn't have had flattened primers at 29. Point was, and is, In My Opinion: there are better choices for the lightweight bullets in the 44 Magnum. If you have good results with it, by all means use it. But take note, that my Quickload workup shows 30 grains as over pressure. (I should have done the QL workup first but didn't) Black_Hog_Down: your primers look good to me. |
