I'm working up loads for my model 88 using 165 gn Partition and 165 SST bullets. A thread here back in 2010 had recommendations for Varget, IMR 4350 and IMR 4064 as preferred powders, the Nosler and Hornady manuals have varying data as much as 2 grains for bullet weight, I understand bullet differences, construction, bearing surfaces, etc. I'm wondering if anybody has some data that has been accurate and with enough terminal velocity for good expansion. I have a supply of 180 gn bullets that I'd like to try as well but my model 88 has a 1 in 12 twist which might be too slow, Barnes recommends a 1 in 11 twist for their 180 TTSX.
