I will be reloading 41 Magnum LSWC bullets. My usual load consists of 9 gr. Unique and standard primers (not a recommendation, just what has proven very accurate for me). I have come across a large supply of magnum primers and am wondering if I should slightly reduce my loading of Unique while using the magnum primers. Any difference in standard and magnum primers with Unique?

Thanks for your insights,

Unique is so easy to light that magnum primers aren't needed. IMX accuracy usually goes down a bit unless you're using "magnum" powders like H-110.

I certainly wouldn't rush out and buy them, but if you got a good deal it will be OK to do as you said. I'd probably drop 0.5 gr. and work up if needed.

Magnum primer will change your ballistics. You knew that. Unique -- not my first choice in large bore propellant. Big fan of Hodgdon H 110 for mag. loads.

I use Unique for reduced and medium loads in the big bores. 296/110 is my favorite for magnum loads. I have one 2400 load in the .41 Magnum that is great.

I took Charlie's advice and reduced my Unique load by 0.5gr with the magnum primers. Got to the indoor range and the loading is superb. Off-hand at 35 feet (I know it not a great distance) 5 rounds into a cloverleaf. One hole; all touching.

It is now well above 100 in my area, so I think reloading is over for the season. My garage gets to about 4,000 degrees.

Obviously you don't have your priorities in the proper order: either put AC in the garage or throw somebody out of a bedroom... :wink:
