[QUOTE="Veteran, post: 2500803, member: 118038"] Granted, there will be many nuances. But, you may find a load that is very close with a little experimentation. You may end up with a little less velocity as well, or maybe close to the same. Groups will likely differ even at the same velocity as your current load due to the nuances you describe and that even though these powders have very close burn rate starting points, the shape and dimensions of the powder burn rate curve will differ in shape and maximums vs. time. Burn rate profile pressure curves plotted vs. time during the explosion will vary some. But you are better off starting at about the same burn rate than not trying to find comps IMO. Groups in MOA may vary due to differing harmonics and bullet exit timing based on all the nuances and the shape of the powder burn rate profile. Still worth trying. Specially if at some point you have no choice. Australian supply is very suspect if there is a China issue in the Pacific....who knows about Canada anymore? etc.... [/QUOTE]
