Still more work to be done, groups were shot in the prone supported (harris bipod) with a butt sand sock. At the moment I have a seating problem due to the 270gr ogive, and my chamber, hence touching lands.
Both the Retumbo and H1000 showed no pressure signs, could go add 1 or 2 grs with H1000, prob add 1/2gr to Retumbo.
As for my 285gr ELD-M load, will leave as is. Need to examine the terminal effects at long range (1000-1400m) on deer. Have had great success on tgts between these ranges.
Was hoping to use the 270gr ELD-X on deer at long range. I believe I can sort the grouping out. More to follow.
