338-06 AI Creme Of Wheat Fire Forming

[shortstuf92]

I just bought a SS Remington 700 with a 24" Magna ported barrel with a H-S Precision Stock in 338-06 Ackley Improved Caliber. I am looking to fire form some 30-06 Winchester brass that I have sized to 338-06 and would like to try the creme of wheat method my question is for people that do this is. What brand and kind of powder are you using and what amount of that powder are you using? I would like to save on the bullets and rifle powder also wear on the barrel. Also does anybody have a good fire forming load with the 200 grain Speer Hot Core bullet or the Hornady 200 grain interlock bullet that I could use for fire forming and hunting at the same time saving components? Thanks

I used to use the cream of wheat method using bullseye for the Mashburn. I found it way easier to shoot 50 rounds of a normal loaf and have perfect cases when I was done. Minimal throat wear and the load I used was completely elk capable if I wanted.

I’d just pick a 338-06 load, near the top end and size up to attain a false shoulder then slightly size the neck so it fits snug in your chamber. Fire 50 off in your leisure and you’ll still have plenty you can hunt with.

Blue Dot and cast for fire forming for me.

If you use the COW fireforming method you'll likely still not get a perfect formed case with sharp shoulders but you'll still be burning primers all the same.

I fire formed some 280rem into 280AckImp by seating the bullets out far enough to firmly contact the lands and provide positive headspace. I used a faster burning powder listed in 280rem data and dropped a grain or so below the max listed 280rem data. I was using blem bullets that I wasn't going to hunt with and I still burned primers but I got trigger time and perfectly formed cases in the process.
