The powdered tungsten stuff we shoot is not monolithic. Monolithic bullets don't compare to this technology as far as terminal performance across a range of impact velocities.
RPM limits are different for different bullets with different jacket designs. A bullet does not have to blow up to have problems. Core to jacket separation can cause big time dispersion and hard to resolve flight dynamics problems.
Powdered core bullet technology should be available to the public within the next 10 months, we are working on it. To produce this stuff in the volume necessary to go public requires very very expensive technology and equipment.
I do not know if Jimmy is making a heavier 30 cal. I bought 10 boxes of 190's and 5 boxes of 210's about 4 years ago and have not ordered anymore. Both lots were outstanding in accuracy, and I just ran out of 210's so if you find out, let me know.
As good as those bullets were, 1/4 MOA or better, I doubt there would be much penalty for spinning them a little faster than needed for stabilization, as long as you did not get too crazy with the velocity and raise that whole core to jacket integrity issue. The 210's shot lights out at 3,180 fps. in a 1/10" Wolf barrel. I suspect you would be good to at least 3,000 maybe faster.
The 210's fly between .660 and .705 depending on vel., twist, range.
That's alot of info and help for others I see. Now this powdered bullet tech will that only be for 30 cals or will something be tried in the 338 family also. Seem as thought it might make a good HOG bullet. Got some of those critters down this way that likes to run off when hit with other bullets.

Pass It On
They won't be runnin off if they get hit with one of these! This stuff is already been in use by some of our bad boys, and a Fed agency or two.
Have you ever seen a 12" X 12" X 24" hunk of gel block get blown clean off a table by a 30 cal bullet?!!!!
Everybody say it together now.......
There are 30 cals for supersonic flight in 253 gr., 200 gr., and 175 gr.
30 cals for subsonic flight in 280 gr., and 300 gr.
IN .223 there are 87 gr., 103 gr., and 147 gr. the heaviest one is for subsonic flight. (think M4 Rock & Roll without the sound.)
The external ballistics of this technology is quite amazing, but when people see the wound ballistics with their own eyes, its like OOOOOO MYYYYYY G__________D!!!!! [img]images/icons/grin.gif[/img] [img]images/icons/grin.gif[/img] [img]images/icons/grin.gif[/img] [img]images/icons/grin.gif[/img]
