and I get flack from some guys on the campfire, when I speak of what a good choice 4064....
just FYI, I shoot the 70 TNT using the old IMR Brown Sheet load data for the 80 grain Sierra.. which is 42.5 grains..
If you can't find 4064 when you run out, IMR 4895 will take the same load data.. at least in each of my 243s, past and present...
3031 is also a darn good choice if you can't find the above two powders on the shelf... .but IMR powders haven't been having an availability problem for quite a while...
oh and just consulted my IMR Brown Sheet, the max charge listed for a 80 grain bullet with 3031 is 39.5 grains...
work up as always, just in case...
but all three are accurate....
30 grains of 4198 also makes a good off season plinking load...
