7mm WSM vs .308

[TwoSixFourWins]

I hunted a few years with a 7mmWSM and it will drop critters farther out than most have the skill to shoot, certainly father than I had the skill or desire to shoot. I used 140 grain ballistic tips, sierra game kings, and 160 grain fail safes and all killed deer dead as dead can be. 7mmWSM held the 1000 yard world record group at one point.

Hey thanks guys.  I was looking at the Ruger Gunsite because of the capacity for a box magazine, and had read some articles singing its praises, so I haven't had a chance to get my hands on one yet. 

But it sounds like I have a higher quality rifle with what I have, so I think I might save the money and spend that money on some other firearm. 

I get confused between the American calibers and metric calibers.  So 7mm > .308

First of all...you will lose by going to the .308, stick with your 7mm WSM and get GOOD bullets...E-tips, TSX/TTSX or MRX/LRX or Partitions/one of the bonded bullets to take care of the near-to-you stuff.  just a bullet performance issue there.

OTOH...plugging for the 30-06....try buying 7mm/any WSM in Podunk's Country Hardware, may or may not have it...but I'll guarantee that they have 7mm RM, 30-06 and 300WM. 

Just dont be like one of my hunting partners who grabbed his .300 Savage model 99 and his .308 ammo...he was TICKED...and hunted with my Super Blackhawk that weekend.

Multiple millimeters by .393.   7 x .393 = .275. 7mm is smaller than .308.

.284 caliber is 7.21 mm. 

I guess they rounded the 7.21 down to 7mm...........  

.277 caliber is actually closer to 7.0 mm.  (So the .270 Win is a 7 mm)..............

Aha!  Finally, the key!  Thanks for that.

@Woodswalker:  So far, I have never grabbed the wrong ammo.  I can only imagine the hell that would come raining down amongst my own hunting camp!

Actually multiply by .0393 .  .284 would be the bullet diameter.  Just as .308 is the bullet diameter of the 30 cal. and .277 for the 270.  If I'm not mistaken you do not start having bullet diameter listed the same as caliber listing until you reach the medium bore cartridges at .338.

What about the 223 Remington, 243 Winchester, and 257 Roberts?

Wouldn't you consider those 22, 6mm and 25 caliber rounds?

That's funny!

Woodswalker, I tried to send you a PM but your box is full.
