I'm working up a couple new loads. A .44 Mag 300gr LBT WFN-GC (Lead Bullet Technologies, Wide Flat Nose - Gas Checked), actual weight approximately 309gr. And a .41 Mag 220gr LBT WFN-GC, actual weight approximately 229gr. Alliant 2400 is my powder of choice.
Both are from Montana Bulletworks. I had a little trouble with the .41 Mag bullets, which I ordered in .411" dia only to find they didn't chamber because they didn't fit the cylinder throats. Fortunately, after a phone conversation with Bruce at MBW (who was very helpful and pleasant, btw) I learned they size to the throat rather than .001" over bore diameter. I sent them back and he was kind enough to resize them free of charge. I've not shot them yet, but they chamber now.
The .44 Mag load is one I've been working on a little more. I actually just replaced my SBH's front sight with one for a 7-1/2" .45LC Blackhawk because I was bottomed out on the rear sight and still hitting 6" or so high. So I have some more of those to test too. Accuracy has not been great off the bench at 25yds but I think a little more powder may tighten it up some. And honestly, the sight issue probably had something to do with it. The limitations of this shooter cannot be ignored either.
My main question is about crimp, because the LBT design has a very different crimp groove to the LSWCs (Lead Semi-WadCutters) I've been shooting regularly. If anyone has experience loading this style of bullet, your input would be appreciated.
.44 mag on the left, .41 mag on the right.
The .44s are new brass. The .41s are once (maybe twice) fired brass as I'm just working up from the suggested starting load, and the first 30 bullets are the ones I loaded before I pulled them to be resized. I only mention that because the crimps do look a little different, but I used what felt to be a similar pressure with each. Both are crimped with Lee FCDs (Factory Crimp Dies).
Once I get the loads to group decently for me, I'll finally run them over my new chrono.
