Echo, I have owned four .338s Sako carbine to full custom M70(s) I now do not own any and do not miss them. None would do 2700fps with 250s. None were better than just OK accurate. I think a 30'06 with 220s @ 2600 is just as good and usually twice as accurate. Now, a 340 WBY pushing 250s @2950fps well under MOA is the only 33 left living with my other guns. Wish I had a dollar for every newby Alaskan with a 338 Ruger and a Tasco 4X12 onboard...
'Kinda like that 33 Whelen picture ya got up there. Best wishes.
That's your experience and from what I've experienced the 338 win mag has been very accurate:
These were shot with 250 gr. bullets too. What's your real agenda with the 338 win mag?
