Thanks DrMike

Thanks to you both for the info. This is the last on my initial load development, but just couldn't find data on it. I'm only going to run speed tests to start. I see no sense anymore in wasting time & $$ on accuracy tests, only to find that it's a moped later. 8208 and RL-15 are on the 'have-on-hand list, if not up to snuff ...LVR next, at least for the 210 PT.

Please keep us up to date on how it works, I will as soon as I can.

What would be the best powder in the 338 federal and the 200gr Speer; my Ruger 77 Hawkeye doesn't shoot it and MR2000 very well. Any QL help out there?

DrMike · Oct 6, 2016

Best? The 338 Federal doesn't appear to be particularly fussy. Any of a number of powders should give you good results. Some I would consider include TAC, RL15, IMR4198, BL(C)2 and A2230.

orchemo · Oct 7, 2016

TAC has worked well for me with the 185 TSX

SJB358 · Oct 8, 2016

W748 isn't a bad one either. Works very well in my 358 Win.

I'm using 8208,2230,LVL and TAC. IMR 8208 is my go to powder for 160-210 gr bullets, AA2230 gets better velocity in the 160-180 range and LVL is best velocity over 210gr. With the 210 Partition I can safely get 2575fps with 8208 and 2625fps with LVL and I don't think any animal is going to notice 75fps.

Shooting 8208 with the 180gn AB I'm getting just under 2800fps
Shooting AA2230 and 160gn TTSX I'm getting just over 3000fps

Now if I can just pick a bullet for whitetail I like them all.

I can tell you as fact, from personal experience, that a 200gr .338 @ 2550fps will spin a 7'3" black bear 270 degrees sideways, in mid air, at 30 yds.

I've got 210's loaded and boxed.....now can some help me find a range that's not 2hrs from the house ?
