Thread: 7mmRM with cast bullets?

In a magnum rifle???? Getting a 303 cast bullet to 2440fps is apparently a task, almost like getting to the moon. Getting it to 3000fps strikes me as trying to get to Mars, I mean has anyone actually tried / done it? I would be fascinated on what had to be done to achieve it!

It has been done there are a bunch of experimenters in the US working on shooting .30 cal cast bullets as fast as possible velocity is over 3000fps with a 165 grain bullet they use super slow twist
barrels of 14" to 16" twist the bullets are cast from a very hard lead mix no good for hunting unless it's cape buffao,

Kind of wondered/suspected this was the case, seems pointless...

It's part of the sport, it has turned up some interesting information on lead bullet and bullet lube composition what works and what doesn't, there are some new bullet designs come out of it,
of course it is only really interesting for those into cast bullets.
