I recently put 9gr of Unique under a 240grn "Elmer" bullet in hopes of finding a medium level .44 magnum round. I know Unique is not the best magnum powder, but for the time being it's what I've got. As you'll see in the accompanying pictures, I came across some unusual effects. Picture I: The dozen rounds I put through (Using a Ruger Super Blackhawk) exhibited flattened primers (cci magnums) that appear as though they had a wire brush taken to them.  Picture II: My cases seem to have imprinted on my loading gate. Perhaps this had happened at some time in the past and I did not notice. However, not that I have noticed it I wonder if it is cause for concern.  Being new to reloading, I am unfamiliar with what might be causing these effects, and whether or not this is a problem. I'd like some input on the above issues before I blow up by pistol. Thanks in advance. |

That all looks fine to me. Normal primer changes, and I have always assumed those marks are the primer picking up the texture of the breech-face machine marks. The imprint on the loading gate is normal as well, just a little friction wear in the bluing from the case moving back and forth under recoil.
Did the rounds feel consistent and mild in recoil, with otherwise normal report and performance?

They did. The round was satisfactory, if a little underpowered for larger game, but they were consistent in recoil and accuracy with a three inch group at 50 yards, which for me is a noteworthy accomplishment.

Picture I: The dozen rounds I put through (Using a Ruger Super Blackhawk) exhibited flattened primers (cci magnums) that appear as though they had a wire brush taken to them. That primer isn’t flat; it bears signature of firing pin bushing. Magnum primers don’t go with Unique, but photo shows no excessive pressure.Picture II: My cases seem to have imprinted on my loading gate. Perhaps this had happened at some time in the past and I did not notice. However, not that I have noticed it I wonder if it is cause for concern. Impact wear to bluing caused by casehead on loading gate and standing breech, along with signature of cylinder ratchet to countersink in standing breech are normal and the result of previous shooting. Being new to reloading, I am unfamiliar with what might be causing these effects, and whether or not this is a problem. I'd like some input on the above issues before I blow up by pistol.

A whole lot of 44 magnum shooters including myself shoot 10 grs. of Unique using 240-250 gr. "Keith" style bullets with standard LP primers every day. Beyond that it's best to go to one of the slower burning powders, & there are many out there that will work fine in your trusty Blackhawk without sudden pressure spikes.

I'll agree with Dick on this one. I use Unique in so many cartridges. This includes big bores like the 480 Ruger, 475 Linebaugh and 500 JRH. It works flawlessly in everything.
Even cast bullet loads in my 30-40 Krag Rolling Blocks get to see a lot of Unique. Never tried it with magnum powders.
As far as those loads not being suitable for big game, don't underestimate them. Not nearly as much power is required as some would have us believe. Usually more range time is a better investment than more power is.
Just my opinion...

Dick Am I to understand you do not mix magnum primers with your Unique recipes? |

There should be no problem with using magnum primers with your unique load, you just need to simply monitor your results as they might cause different effects with comparable loads compared to standard primers,......not adverse effects just different.
I agree with the previous comments on your current effects those are not adverse, the primers may be flatter and imprinted with frame marks but they do not appear to be what I would call "flattened" from hot loads.

Your load is fine. If you're happy with it otherwise, by all means use it.
