[QUOTE="Swamplord, post: 2614438, member: 2460"] Didn't have much time to shoot yesterday, moose hunting a few hours in the morning, cabin pilings going in during the day & shooting a few rounds, then hunting a few hours till dark .... Shot the first round & Magneto said low 3382 fps for the 106.0 gr load of LRT... so I skipped shooting all of the loads to save bullets, primers & powder, I only shot one round of each load to get an idea on velocity & pressure indicators on the brass ... with no high pressures found I shot all 5 of the 112.5 gr loads just to make sure ... All cases extracted without any effort with zero signs of high pressure on primers or case heads, could barely see the imprint of expansion at the .200" height around case head & all cases looked the same from lowest to highest charge, one reason I like super shiny polished brass for load development, every minute difference in pressure shows up, like a detailed road map ! I don't think there is enough room in the ADG 300 RUM brass for the LRT powder to reach high pressures, at 112.5 gr there is quite a bit of powder compression to seat the bullets at 3.636" with no room for more powder... And can't seat the bullet out due to the design requiring neck contact with upper band for bullet alignment Might be able to get another grain of powder in thinner cased head brass like Norma/Nosler or Hornady but pressures will be offset and not much gain in velocity will likely occur ... Pretty much can list LRT as a bit too slow of a powder for the super slick 153 gr Afterburner bullet in the 300 RUM The remaining four 112.0 gr loads were in my 300 RUM last night, moose hunting ! So technically you can say that the 153 gr Afterburner is "Gone Hunting" .... for moose in Alaska 106.0 gr = 3382 fps 107.0 gr = 3469 fps 108.0 gr = 3414 fps 109.0 gr = 3434 fps 109.5 gr = 3447 fps 110.5 gr = 3451 fps 111.0 gr = 3461 fps 111.5 gr = 3487 fps 112.0 gr = 3497 fps 112.5 gr = 3468 fps 112.5 gr = 3522 fps 112.5 gr = 3494 fps 112.5 gr = 3516 fps 112.5 gr = 3518 fps ...[ATTACH type="full"]392772[/ATTACH][ATTACH type="full"]392773[/ATTACH][ATTACH type="full"]392774[/ATTACH] [/QUOTE]
