bullet diameter for 41 Swiss
Yesterday at 5:50pm
Print Post  
Anyone here shooting a 41 Swiss ?   What bullet diameter do you use ?   Wiki says .418"    Lee precision has a fairly new mold for the 41 Swiss that drops at .418"
I had thought the 41 Swiss used a larger diameter bullet at about .429"  I have Ideal mold # 427103 that drops at .429" that I thought was for the 41 Swiss but am not sure now.
Would appreciate some help getting straightened out on this.
I dont have a rifle for the 41 Swiss I am just trying to offer the correct bullets for it.

I use the Lee mold 430-310-RF and size them to .431 for a Swiss Vetterli. I haven't done any grouping with this bullet only hitting steel. These are loaded in reformed 8 Lebel cases.

The original .41 Swiss ammo I have is paper patched.  I suspect the bullets are in the 0.415-0.418 range with paper to bring them up to groove diameter.  I’ve only ever loaded mine with the same grease groove bullets Rafter mentioned, but I ran them as dropped from the mold.

So…. Both diameters are right depending….
