Which powder for .338WM and 200gr. ballistic tips?

[wombat13]

My FIL likes the 200 gr ballistic tip in his .338WM for deer hunting (the Combined Technologies coated Nosler Ballistic Tip). It appears that ammo is no longer made and with the shortage of ammo right now, I told him I'd load some ammo for him.

I've got the bullets, dies, and some brass on the way. I just need to decide which powder to try first. Based on Hodgdon, Accurate, and Alliant's websites, the best powders that I have are: RL17, AA4350, IMR4350, H4831, IMR4831. I have only one pound of RL17 and several pounds each of the others. I also have several pounds of H4895, but the published velocity is a bit lower than the others. Which powder should I start with?

Also, is there a must have powder for .338WM that I haven't listed? Powder can be hard to find, but now that I'm loading for .338WM I'd like to keep my eyes open.

I use IMR4350 for my 338WM. I believe the charge is compressed or damn close as I have had good luck with 68.5 grains under a Hornady 200gr SST.

I show a start of 61.1gr and a high of 72.4gr in both of my Hornady manuals.

Lee shows start 69.6gr and a high 74.0gr both as compressed for a 200gr bullet.

Thanks for the info. Lee data matches the Hodgdon online data. So your load is a starting load and it is compressed?

Compressed charges aren’t a problem with IMR4350. It is a very coarse extruded (stick) powder and relatively slow. It is a particularly good match to the .338winmag.

Should be very accurate to!

Well, it looks like IMR 4350 is the one. Thanks for the replies.
