7MM WSM Unpopular
 

Everything I read says that the 7mm wsm are not selling nearly as much as the .270.300 wsm. I looked up the balistics and the 7 looks good when compared to the 270 wsm. Why is the wsm so unpopular?

RE: 7MM WSM Unpopular
 

MM cartridges have never been as popular in the U.S. As in other parts of the world. The 7MM Rem Mag was an exception but it was about the only exception. Remington introduced the 5MM and it failed. The 6MM compared to the 243 also didn't catch on. Remington introduced the 8MM and it went nowhere. The 10MM didn't do much and if not picked up by the Military, the 9MM may not have made a splash either. As long as I can remember there just has not been much support in America for the Metric system. Also I think that the popularity of the 300 WSM has hurt the sales of the 7MM WSM. What can the 7MM WSM do that the 300 can't do as well or better. The 270 WSM fills the need better for a smaller caliber and the 270 which has always been popular benifited from tacking Magnum on the end as well as catching onto the Short Fat trend. Thats My thoughts on the subject. Others may have more ideas.

RE: 7MM WSM Unpopular
 

I think in actuality the 7mm WSM offers nothing over the established 7mm Rem Mag. The 300 WSM is only popular because it came out first and was the latest and greatest, but it offers nothing over the 300 Win Mag. The 270 WSM offers better ballistics over the 270 Win, and costs less then the 270 Weatherby Mag so it is the only WSM that actually fills a niche.

I just bought a 7mm WSM a month or so ago........ only other option I was even looking at was a 270..... the 300 mag outshoots the 300 WSM....... and the 7mmWSM outshoots all of them

RE: 7MM WSM Unpopular
 

Those numbers mean nothing. What bullet weight are you using for each? I think your math may be a bit off in favor of your new baby.

RE: 7MM WSM Unpopular
 

those are all based on a 150 gr bullet......... i didnt do the math it was off of one of the ammunition manufacturers website

RE: 7MM WSM Unpopular
 

There you go then. You can't lump them all together with one bullet weight.

RE: 7MM WSM Unpopular
 

no my baby will always be my trusty ol .30 .30 ive used for years and years.....lol

RE: 7MM WSM Unpopular
 

honestly I see mroe .270 around here than anything else......... the 7mm equates to a .284......... I chose it cause it has good ballistics and is in in between caliber of the .270 and the .300/.30 06
