.41 magnum man
Member
I know that load data from different sources may not agree on certain points.
But I have a couple questions regarding that issue involving my .41 magnum.
One book I use to load 2400 powder says at 17.6 gr. of powder I should be getting around 1200 velocity. On the Alliant website, they say with that load I should be getting 1400 velocity. That is a pretty big jump in numbers to me. I only found the Alliant reloading data today, and I am wondering if I should probably be more inclined to go by that since this powder is made by them? Another thing Alliant mentions is that is a revolver with a 5.8" bbl. whereas my book doesn't mention bbl. length. Mine is a 6 1/2 barrel. I guess barrel length will play a role in velocity too, but to what degree?
Now another thing I noticed is the oal is different. Alliance says O.A.L. should be minimum of 1.575, but my book simply says 1.580 maximum. The ammo I have been loading is usually between 1.575 and 1.579, but some of them have been as short as 1.570. What kind of tolerance is there on the over all length that is considered safe? Now, I have shot quite a few loads at the shorter length, and have had no problems, but I am still new at this.
So, how about some thoughts from you pros? Thanks!
