This is mostly the sort of results I get with the RWS HIT in my .30-06.
What I am going to do when reloading the next batch is wind the velocities back to more "normal" levels as I think the "lighter bullet, higher velocity" thing has an upper limit. So wind the 270 110's back to 3150 or similar at the muzzle. So impacts at 100 yards are below 3000.

Quartz sand = 7
Copper = 8.89
Lead = 11.35
Being a lateral thinker according to my old Aachen University graduate boss :-
When working in Buenos Aries in 1996 I experimented with home made Glaser style safety slugs by melting out the lead from some .358 cal jacketet 180 gr Hornady InterLock Spire point single shot pistol bullets and filling the jackets up with #9 shot won from from shotgun shells then topped it off with an epoxy puddle to hold them in. End weight was 90 grs. I was getting an estimated 1900 fps from my 10 inch "scoped" Contender .357 Mag barrel with a louder boom and muzzle flash as proven by the crowds standing behind me at the range after my shooting it (WTFWT) but the accuracy I achieved astounded me as they were hitting dead on as with my normal .357 ammo, my theory is that the centrifugal forces from the rifling stabilized the projectile very well at the 300,000 revs per minute that it left the spout at.
Now lets take a rifle .270 Win 150 grainer soft point bullet say, melt out the lead then fill up the jacket with fine Quartz sand to achieve a better fill than #9 shot would acting almost like a solid, centrifugal force should function here too then top off the sand with epoxy and try it on targets first. A thick copper jacket and sand would be eco friendly and much cheaper than turning up copper/brass bullets.
Maybe it works as a fox load and might make shooting edible game an option. naturally it would need lots of testing first.
I will make up some testers for my Ruger #1 as it is a very strong action. Only the copper jacket will contact the bore so no worse wear wise than all the presently used projectiles. Might be mightily cheaper too.
