8mm Lebel cast bullet load help?

[mkj4him]

I live on a river. I shot from my deck down into the edge of the water, passing through a foot of water before digging into the soft sandy bottom.
The recovered bullet was mushroomed and had a retained weight of about 51%. 118.9 grains remained of the 234.

Just looking at original 8x50Rmm ball N data,
15 g (231 gr) Balle N FMJ 690 m/s (2,300 ft/s) 3,751 J (2,767 ft⋅lbf)

So if a 231gr FMJ is safe at 2300 FPS, I should be in safe territory with my 234gr PC cast at 2157 FPS with still room to go up a bit. I just don’t want to go past a safe level. So far I’ve seen no leading.

Its not that its unsafe going faster but it just wont be accurate.

Thank you. I’m going to back down the ladder scale a bit. Find a sweet spot.

I shoot 13 grains of unique and the lee .329 in my berthier. 8 grains of unique and a pb boolit it also works well.

Not specific to the Lebel but If you haven't read what Ed Harris had to say about cast in military rifles it is a good place to start. http://www.castpics.net/subsite2/Cla...y%20rifles.pdf

Hey, something I’ve done is take load max load data for H4895 and use the 60% reduced load and replace a same weight cast bullet for the lead bullet in my Carcano with coated gas checked, seemed to work well, velocity was around 22LR speed.
