[QUOTE="codyadams, post: 1844701, member: 87243"] Ok, got some data. Peterson brass GM215M 270 Badlands Super Bulldozer, HBN coated Seated .025" off, 3.819" OAL H1000: 87.0 - 2782 88.0 - 2801 89.0 - 2846, beginning pressure signs on primer, discontinued work up Retumbo: 88.0 - 2803 89.0 - 2823 90.0 - 2858, beginning pressure signs on primer, but didn't notice it in the dark shoot house. 91.0 - 2906, very light bolt lift, discontinued work up VV-N-570: 91.0 - 2923, light pressure signs on primer, did not shoot more These 270 Bulldozers seem to pressure up somewhat early than I figured they would, they are 5 grains heavier than the ABLR's that I loaded but they were uncoated and these are HBN coated so I figured that would offset, the monolithic design must be building a little pressure. I will certainly be able to pressure up with VV N-570, I will do another work up with it starting at 86 and working up to 90. From what I have seen on this work up, with VV N-570 I should be able to get 2900 or just under for a safe max, H1000 would probably get 2800 at a safe max, and Retumbo would land around 2825 for a safe max. Keep in mind, I'm using a 24" barrel, with the 26"+ barrels on most 338 NM's, I would think you would get another 50-150 fps than I am seeing. As far as accuracy, I think these gonna shoot....H1000 and Retumbo both respectively made 3 and 4 shot groups at or just under an inch. [/QUOTE]
