22-243vs 22-250
I have not looked to see just what the density of toungsten is but why not just take a 22-250 60grs HP at 3600fps and work up a load for your toungsten rounds from there, you can readily get the cases for the 22-250, also would not the barrel life be very short for a 1 in 5 twist even if it is only traveling 3000fps, and for those that just want a 100gr bullet traveling 3000fps go to a Hornady Spire Point#2450 in your 243 with 47.4 grs of WIN 785 powder or 48.2grs of H450 for about 3100fps.
But then there are those out there that just want to have a bullet that noon else has, why do you want such a slow Round ? Spade says Quote "
ive seen it on a 22 hornet and 204 ruger before. IF you load too hot, the bullet actually tears itself apart on the way to the target."
I personaly have never seen one blow apart but both of those rounds travel at speeds fast enough to disintigrate the bullet if they even hit a bug in flight or a blade of grass.
