I've read all of this thread so far..

I haven't posted BECAUSE I haven't bought primers in a long time. ALL my testing is 80's vintage..so take that into consideration.

...... except for the very old days when WW made just one primer, the old 8 1/2-120,which was pretty potent I guess.

But since then I have used only WW mags and the Fed215.


SAME HERE except I've not tried the 215s.

Bob - the last primer testing I did was AFTER WW brought out their LRMP. I tested/compared the older WW 8 1/2-120 against their WW LRMP******** there was NO DIFFERRENCE over the graph OR on paper. I have BOTH and use 'em.


NOW I don't have any idea what the NEWER primes are doing. I've noticed that WW primers are brass colored..ALL mine are silver.



Back in the 'olden' days of 70-80s I read more than once to use Mag primers with 'ball' powders OR charges 'over 60 grs.'
