Most will say 1-10, but you can also run the 1-11 quite easily also. That is the go to twist for the WSMs with 210s so sure the win mag will run them also.

If you are sure you will never want to shoot heavier than 200, I would go with the 11. Chance for accuracy is better.......Rich

I've never shot a 200gr bullet out of 1/11 twist barrel so cann't say how the velocity compares to the 1/10 twist barrels. Years ago build a 30-338mag (338mag case) used a 1/12 twist barrel just to shoot the 165gr bullets later had another one build used a 1/10 twist barrel for the 180/200gr bullets.

Had a 30-06 with 1/10 Kreiger barrel and it was alittle faster than the 1/11 twist barrels (Lilja/Bartlein) using the same loads 180gr bullets and the 1/11 twist were faster with 165/168gr bullets.

I'm always playing around with twist myself I'd use a 1/10 twist for the 180/200gr bullets. Well good luck
