Re: 300 win mag versus 300 remington utlra mag
I have a .300win mag H-S Precision rifle with a 26" barrel.
Accuracy is great.
I get 3400fps with 165gr loads.
3250fps with 180gr loads.
3050 with 200gr loads.
I think you can better those by up to 200fps but at quite a price in increased powder and recoil.
Unless you can really make use of that extra velocity, I would go with the .300win mag.
