I know it's a long shot, however -

Looking for some .411 bullets for my 405 Winchester. I've got brass, just need some 300 grain or possibly even heavier will work.

Thanks

I have a sealed box of 50 and another open box with 14 of the Hornady .411 300GR SP # 41041.
Midway gets $49.49, when in stock: https://www.midwayusa.com/product/1010471518
If you want these, I will sell you the lot of 64 for $60 shipped, Priority Mail.
Would also take a trade for other reloading components I could use.

Hawk makes bullets for it too

I have some. Will check tonight

The (64) Hornady .411 300GR SP # 41041 bullets I mentioned in my post above have been spoken for. A trade was made, and they are no longer available.
