Today i was over the hill and had two groups of 5 shells loaded up....see i had an idea last night from the guy who used to shoot at that famous warehouse where all the benchrest guys shoot those 0.0x groups at 100 yards and this guy who has shot more 0.0x groups than anyone else said he could tell if the bullet would group with the others by how it """felt"" when using his seating die.... so i have a forster ultra seater and FL die set that came in yesterday and i noticed they are much smoother than the rcbs dies i upgraded from but the ultra seater had tension when the bullet got seated some stiff then lose to stiff again they just didnt feel the same so i had a revelation..i took this ultra high grade car wax if you want the name of it just ask we are not talkin turtle wax here...and waxed the inside of the case neck as well as the bullet itself....polished them up with a cue tip for the shell and my t shirt for the bullets and began to seat them in the forster ultra.......i noticed on the first bullet....smooth like glass even pressure the whole way no hard easy hard just like glass.....so went and shot them today at 500 yards i know its a chip shot but far enough to see effect on group size without having to walk the 2000 yard roundtrip to bing at 1K
first 5 unwaxed same seating depth 20 K off the lands 162 amax 65.0 gr of rl 17 a minute between shots...measured group 5.6 inches
went back and shot the next five that were waxed and seated like glass ....shot those five walked down and measurd ....2.4 inches !! 3 of which were within an inch of each other....WTF ? same seating depth 20k off lands same exact charge weight 65.0 gr rl 17.....needless to say 3 shot groups can be flukes but not 5 shot groups i will be investigating this phenominon tommarro
