First post. 6.5x284 ladder test problem
This is my first post here, but I would like to thank everyone for giving me a wealth of information and access to their experience so far. Have used this forum many times as a reference book!!
I have just re barrelled my old Remy 700 with a 6.5x284 30" Krieger tube. I am going thru the 500 yard ladder test and got some unexpected results. Using berger 140 hybrids and H4831sc I worked loads up from (hodgdens manual) 45.0 to 49.5 in 0.3 grain increments. No pressure signs throughout and got an accuracy node at 48.9-49.2-49.5 great but only reached 2722fps to 2744fps. I got a berger manual that gave a max of 51.0 grains, and with many people loading the 6.5x284 well beyond that I did another ladder test from 49.8gr h4831sc to 53.0. The only pressure sign I got was at 53.0gr. There was the very slightest ejector ring. Not a bulge, just a slight shiny half ring. Had another accuracy node at 52.6-52.8-53.0gr, giving a very flat velocity values of 2980, 2982 and 2982 for each increment. The vertical element was only a half inch!! Question is, why did the 3 final loads result in the same velocity. Is it safe to continue at these loads even tho there was no hard bolt openings, no primer signs or anything. The final velocity is more or less what most people find accurate in this caliber. Thanks in advance and well done on an amazing forum!!
