Info as follows:

Rem 700/26 in Lilja barrel/ATRS muzzle brake

Norma Brass/Retumbo/CCI 250 Primers/Seated 10 thou off the lands (Fits in the H and S Precision mags with room to spare)/60 deg F/All ammo at ambient/Magneto Speed V2

75 gr Retumbo/Not a compressed load, but very little space left/5 rds/2805 fps/No pressure signs/No vertical stringing

76 gr Retumbo/Slightly compressed/5 rds/2846 fps/Light ejector marks on all cases/Approx .6 MOA vertical stringing

77 gr Retumbo/Compressed/5 rds/2888 fps/Defined ejector marks on all cases/1 x stiff bolt lift/Approx .8 MOA vertical stringing

Hope that is helpfull to some. Plan to refine load between 74 and 75 gr of Retumbo. Will work with H1000 once I'm done testing with Retumbo. Am very pleased to get 2800 fps with the combo with no pressure signs.
