I cannot fix your ignorance in this accuracy matter. I'm the information messenger, not its originator.

You might want to get mean on Handloader magazine editors for their late 1991 article on Sierra's 155 grain Palma bullet tests. The ammo had a 3/10ths grain spread of IMR4895 that produced the 20-shot 2.7" group at 600 yards pictured therein. .45 MOA. New cases with up to .003" bullet runout. Impossible for most to believe.

When on an accuracy node, 3-tenths can/could hold together well enough. But holding 1-tenth on top of that same accuracy node, would be a guarantee to hold together even better.
And a lot of difference then the depiction capability of any 3-tenths at random.

The 20-shots into 2.7" at 600yds in 1991, is whole lot more probable and realistic compared to the 40-shots into a 1.92" group at 600yds in 1971, that you also claim occurred.

Mid Tompkins claimed that; he did it. I'm just the messenger.

guys, i've been posting a lot cause this is my first time reloading and I have probably been posting some very newbie questions. there are some very smart and experienced people on here and i would feel pretty bad if one of my stupid questions caused a very unneeded arguement. i'm positive you are both very smart and know the same thing, it's just typing instead of talking,,,i think, can make it seem like each person is looking at something from a slightly different angle even though they both are really on the same page. i'm just saying i think both you guys are right about this and that our typing words is where the breakdown is.

anyway, i am in a hurry to post my ridiculous question thread for the day

I think they like each other alot, but they're not wanting to let on to it.
I do find one of thier postings more informative than the others though.

It's been suggested that the "messenger" has been repeatedly in error in the retelling, by reporting Inch group sizes that were actually MOA group sizes.
