I was planning on using my 270 win for a cow elk hunt this year(150 grain NP), but got a new scope for my 338 win and am thinking about using it instead. I have 50 200 grain accubonds loaded for the 338, but I saw that the SD for the 270 is a higher. Is the 200 grain accubond in 338 win sufficient for elk, or is it more of a deer bullet?

I use 210 gr. Noslers and 300 gr. Woodlieghs in my .338 Win depending on where I'm hunting..They have worked so well that I see no reason to change..However, I am sure the 200 gr.accubonds will work on cow elk..

Accubonds are very good elk bullets.

I would opt for the partition or some Swifts in the 225 grain bullets.

You would have heck killing one any better with anything.
A 200 grain accubond in a 338 will absolutely flatten a cow elk.
A friend of mine shot a BIG bull in Colorado last year with a 180 grain AB in his 338 through the shoulder and it exited through the off ribs.

Believe me when I say that you will NOT be undergunned.

I used them last year in my 338-06. Flattened the 5x6 bull I shot with full penetration of the chest. I will use them again this year for my cow hunt.

I used the old 200 gr NBTs on a bull elk several years ago at about 200 yds and it work great. One shot, one kill. The Accubond is the same bullet but improved. I will be using the 260 grainer in my 375 H&H for elk, when I get home from paradise. I wish I could fit the 225 grainer in my 358 Win.

If you are going to use a light 200-210gr bullet, the NAB is a good one. I've had such great performance from the 210grNP I haven't wanted to switch.

That's good to hear. Thanks for the replies.
