[QUOTE="msilbernagel, post: 2645533, member: 117619"] Hello Everyone, I'm working with my son-in-law to work up a load for a 338 Win Mag, with Hornady 200gr SST bullets. Naturally, finding the power you'd like can be challenging - but I do have an unopened 8lb container of IMR 4451, Challenge is - Neither Hogdon nor Hornady offer information on loads using that powder, though the H4350 and IMR 4350 seem like good choices in their load data. Scanning forums and previous posts I find little that seems definitive. So - here's my question: How close are H4350 and IMR 4451? A few have mentioned using IMR 4451 as a replacement but weren't clear on exactly how close it comes. From what I have read, and lacking hard data, I am inclined to do ladder tests using the H4350 min/max, work up to Max watching for pressure signs, and monitoring velocity with the magneto speed. Thoughts / comments on this notion? Any favorite loads using that bullet or something close? This doesn't seem like a popular / common enough cartridge.. so good load data seems scarce. Thank you Mark [/QUOTE]
