Going back to one of your earlier posts, I do not think there is any way that I could put a .458 in .451/.452 “crush rib” rib and get it down the barrel… I have never tried it, but that should work well in your tight sabot theory. And as I understand the Savage and the use of smokeless powder you really do have to have a tight sabot to get progressive powder to burn correctly. Lee has tried to explain it to me a couple of times. So yes, I do use the MMP Orange sabot to shoot .458’s, but then your statement about the Savage, the .458, in a “crush rib” really leans me to my thought that the “crush rib” really is to loose/thin for most bores shooting the correct bullet in it.
I have never said that the “crush rib” was inaccurate; my suggestion was that the “crush rib” leaks gas from my ML’s that the 3p did not. The “crush rib” was designed to load in very tight bores and it should be used there but to use them in a bore that does not need them, might cause a loss of velocity. Now then if you are loading them because they are easier to load and they are accurate, gees! that sounds like a Power Belt, then that is your choice. And using them for a second quick shot really might be the place for them. For me, since I shoot a semi-fouled bore it really makes no difference my second load – loads the same way as the first.
Agreed, these are the sabots for tight bores. If they are accurate, I think that is more important than loss of speed, butI really didn't expect to seea 200 fps loss, that is pretty significant, since most folks shooting another 50g pellet will only get a 400 fps increase in velocity, so this is about 1/2 of that, which is a lot. So in general I agree with you, if you can use an MMP that fits tight, then do so.
