Lyman Plains Bullet Project

Even though i have really nice custom molds built for my rifles i stil can't help myself from trying new things, i enjoy tinkering with this stuff!! My .50 Cal Stainless Green Mountain LRH barrel likes harder lead, i poured up a batch of Lyman plains that are in the 9.5 Brinell hardness, i lubed and sized these bullets down to .492, i will wrap my 2 wraps of onion skin paper and probably send them through my .500 Die (wont really do anything other than smooth the paper a tiny bit)
I also poured up some Lyman Plains .54 Cal bullets from Soft pure lead, my .54s like softer lead, i sized these bullets down to .532, i will do the same 2 Wraps of onion skin paper and send them through a .539 (again wont do anything besides smooth the paper out a bit)
I made my own .492 Sizing die and have been playing with the S&W 500 Bullet again with STELLAR results! These oversize bullets can be sized down like this no problem, PLENTY of Lube is your friend here, along with speed, when you start the push follow through to the end, you don't wanna stop and restart, if you follow these 2 steps these oversize bullets slide through like butter!!

Here are the HARD lead .50s

And here are the Soft Lead .54s

I'm looking forward to seeing what your results are!

What are the rifling twists for these?

I have a feeling they'll do well and land with quite a wollip!

.50 Cal twist Rate is 1:28, and my .54s are 1:28, and 1:32, I have shot this bullet through the 1:32 Lyman Plains and the 1:28 .50 Cal with VERY good results, the main difference here is that i sized the bullet down to a correct Paper Patch Diameter and have not done this before with this particular bullet, I plan to shoot these soon, might even do this today

The .50s weigh in at 395 Grains, and the .54s weigh in at 460 Grains

I shot the harder lead .50s this morning at 50 yards from my Green Mountain LRH Stainless .50 Cal, 1.75" 3 shot group, I am confident i can get this better with a powder adjustment, but this was a good start. My next outing will likely be with my new .54 GM LRH when it gets here, hoping to see it by the end of this week, hopefully!
