So where is the big differance?

I was looking at the 7mm WSM shooting the 180gr Berger at close to 2950 both rifles having a 26"barrel

So what would be a advantage to a 300 WIN MAG and the 210 there does not seem to be that much of an advantage....................other than a bullet that is 30gr heavier?

SD seem to to almost the same and Velocity really close....................

The advantage, IMO, is in reduced wind affect at long ranges.

In a hunting application, the larger .308 bullet is going to hit harder than the .284 bullet.

Re: So where is the big differance?

First off, let me say this...I own rifles chambered from .17 HMR up to .45-70...So this is just me going off of statistics, vs bias opinion as to which caliber I would prefer. I'll save my biased opinion for the very end of the post.

I feel there would be very little difference in wind deflection. The slightly heavier weight of the .30 is contradicted by it's larger diameter which is not as slippery in the wind, thanks to a greater surface area. The smaller diameter 7mm that is a little lighter, will be a little more slippery but is also a lighter weight bullet.

I would be willing to bet they would be so close in performance at 1000 yards, that the only way you could tell the difference would be to shoot them mechanically in a fixed rest, without human error. And even then I doubt you would see any sort of significant difference in wind deflection.

But that is my opinion, i'm not a human ballistics computer.

I also don't own either caliber, just going off of basic statistics and common equation properties such as diameter, weight, length, velocity, etc...

Now for the bias...

Since there would be no real difference, I would go with the 7mm WSM, but I'm also a bigger fan of the 7mm calibers than I am the .30's. Althought I do own a number of different .30 caliber rifles in several differnt chamberings. I like them both, and you wouldn't go wrong with either caliber, but my bias pushes me towards 7mm calibers.

Re: So where is the big differance?

Now, because I don't own both, don't take my opinion as the God's honest truth....Because I don't know that to be fact.

I was just stating how my brain works on that.

I'm sure others can chime in with more experience with each caliber.

Never take just 1 persson's word for it. Always take it all in, and weight out the good from the bad, and make your own informed decision.

So, I would wait for others to chime in with their $0.02 before making up my mind.
