Gentlemen, I have been loading my .44 Mag with 240 gr. laser-cast bullets over either 23.0 gr. H110 or 10.0 gr. Unique. I have used standard large pistol primers for both loads. When shooting the H110 loads, there is a lot of unburned powder residue in the barrel after shooting. Would magnum primers do a better job of igniting the entire charge, or would they raise pressures to unacceptable levels? Thanks for the help Joel Slate | ||

Joel, back of your charge to 22.5gr & go w/ the mag primer. You can work up to the 23gr if everything seems fine. This should help your unburned powder problem. Std. primers w/ the Unique load should be fine. | |||

Joel: You did not mention what brand of standard primers you are using in your 44 Mag loads. Generally speaking, they would seem hot enough. They are all you need with the Unique loads for sure. I have been using Winchester Large Pistol primers for my big bore pistol loading the last few years. They say right on the box that they are for standard or magnum loads. I have found that WW 296 and H 110 just tend to leave lots of powder residue in some loadings. I used to own a S & W Model 57 chambered in .41 Magnum that left all sorts of unburned powder with those two powders, not matter what I tried. If you want to try a magnum primer with the H 110 loads you should back off a little if you are close to maximum and work up again. I have seen more than one recommendation as of late that says you should not use magnum primers with 2400 powder, as it WILL cause higher pressures. (Maybe Elmer Keith knew what he was talking about.) R Flowers | |||

quote: I do not know the podwer charge you were using but can tell you from first hand experience that using CCI-350 primers would have cured that problem. I have used both the WLP & CCI-350. I keep the WLP for light cast bullet loads and the CCI's for ALL magnum loads of H110 or W296. No problems with excessive unburnt powder. mike ------------------ America, Love it or LEAVE IT! | |||

jrslate, 23 grains of 110 with cast bullets, doesn't that lead your barrel pretty bad? | ||

A good rule of thumb is to always use magnum primers when using ball powder...as for your Unique load, that is kind of a light load for a .44 Mag. Try using .44 Special cases, and with both loads, use a good roll-crimp. | |||

Gentlemen, Thank you so much for all of the help. The lead bullets with the H110 load does lead the barrel some, and I am not sure if gas checks would help that out or not. I will try the magnum primers, and I will definitly back off the load a half a grain or so with the H110. The Unique loads are just a lot of fun to shoot. Joel Slate | |||

quote: Mike: Not wanting to be argumentative here, BUT, I tried CCI 350 primers in that darned .41 magnum and Nothing, but Nothing would solve the unburned powder problem. I was trying to get a max load out of that gun and could not get good performance with 296 or H110. I wound up using Blue Dot and got clean burning, better groups, and even a little better speeds. 2400 also did well in that gun, but 296 and H110 were a bust. In the Ruger 41 mag I own currently, I have no such problems with unburned powder, go figure! My best load in this Ruger 41 mag is with 2400 powder. Thanks, R Flowers | |||

H110 will leave unburned powder with lighter bullets. If you really want to use H110 to its potential in a 44 mag, then use 300 gr or heavier bullets. For the 240 and lighter 2400 is a good powder, doesn't need mag primers, and achieves nearly the same velocity, with noteably lighter charges of powder. To the original question, I've always used CCI 350's with H110, but with 2400, unique, univ. clays and red dot, CCI 300's. | |||

I had the exact opposite problem. With Unique, I have that problem, and with 23g of H110, I don't. The Unique seems quite dirty no matter how you slice it. I always use magnum primers no matter what. Why? I don't know any reason not to. Also keeps it consistent. | ||

Try a heavier crimp. H110 almost always benefits from an extra heavy crimp. | ||
