i took your guys advice and started out with a 308 when i was wanting to go with a 300. i have it in the m700 ss and i love this gun but some day i want to move up to a 300wm or swm. when i do will the barreled action bolt up to my stock and trigger? i was wanting to go with a aics but i dont want to spend that kind of money on something im planning on moving up from. it would be real nice if i could just switch them back and forth and have the price of one gun in two.

Since you have a 308 now i assume you have a short action, to upgrade to the 300 win mag you will need a whole new action.Just so that you dont have to go threw that i would go with the 300 WSM it will fit in a short action and you will not have to worry if you buy a stock now, you might want to look if AI make a mag that functions with the WSM rounds.
 
Re: 308 to 300wm or 300swm

Go to a 6.5( 6.5 Creedmoor/ .260) or 6mm(.243) short action instead of the WSM. You will get the same performance as far as drop and wind. Also you can use the same mags as a .308 and not worry about feeding or OAL issues that can come from a WSM in a short action.

Also look at the Manners Stocks with the Mini Chassis system. It's drop in and bolt up like the AICS but in more stock choies. Gives you the AICS mag DBM also.

I agree 100%, I got rid of my 300wsm and went to the 260 and I couldn't be happier. I had a few problems chanbering my 300 wsm which seem to come at a bad time everytime. The ballistics for the .264 cal. 140 Bergers compared to the 30 cal. 210 Bergers is pretty dang close. Good Luck!!!
 
Re: 308 to 300wm or 300swm

Yes, the 300wsm is just as good as the 300wm. I believe that you would just need a new bolt and barrel. My 300wsm before I sold it was great but I really liked the ballistics of the 260 so I sold it and got a Savage 12 LRP. If you did decide to look at the 260, you would only need to change out the barrel. Good Luck!!

What are you using the rifle for? Distances you plan to shoot? Do you reload? etc?

If you are using it for target shooting, deer or smaller hunting, and don't reload....then get a 6.5 Creedmoor. The reload is less, barrel life is fair, bullet drop better/less, accuracy with hornandy ammo is excellent, feeds well from a magazine.

(plus+1 also) , Just like you are saying for the Short-Action platform . IF you choose a Fast vel. 6mm or 6.5 or even the .30 cal. 155 grn. & move them fast you get similar performance to a point . & all run with less Powder & Heat . Me running 155's out one of my .308 platforms @ 3000 vel . They run similar Holdovers Neck-&-Neck with my .300wm out to about 800 yard except for the WindHold .

( to the OP )
I have .300WM & my brother has .300SM . & Shooting .300wm & .300 SM side-x-side I don't see much difference .
& You 'Need' a .308 for repetitious training/shooting . but You wont have & get the authority & feeling of satisfaction of Hard-hitting power on the steel hangers & with the better Windholds like having a .300 mag. & the .300 mag. stands on a different plateau of it's own .
I can't live without a .308 & have two of them . My .300wm is a BasAss Hammer though & I love it . It is a real performer & it proves it every time I take it out with my other .308's . & plus it really hits louder & swings the Plates harder with also more 1st Round hits .

my rifle is just for target shooting and maybe some long distance hunting. i would like to consistanly shoot 1000yrd goups. but, when i get there i will probaly want more. and yes i do reload. my main problem is when i shoot this 308 to its max i am going to want to go further.

a 260 is definately something i will consider. i have heard nothing but good things about this caliber.

yeah sure

some years back i witnessed a alberta doe eat a cross body diagonal 300wsm , it ran 100 pluss yard puking blood and had to be run down and then have its throat cut to put it away.....really bad shot placement however,,,,post mortem showed plenty of broken ham bone and jello lungs and heart.

then
a friend just back from africa reports that he hit a blue wildabeest THREE times from roughly 50 yd in the brush before it finally went down......plus another $2,000.00 on two separate animals that were hit, bled ,tracked, but could not be harvested

seems like a couple of very expensive lessons to me.

sounds to me that the lesson that should have been learned from that is maybe they should try another hobbie. a 300 wsm is hard hitting. i saw a whitetail get hit with a heart shot with win silver ballistic tips and it was down there with shell shock from nose to asshole. my whitetail round is either 22-250 or 243. there is no need for anything bigger, i like to have more than just deerburger.
 
Re: 308 to 300wm or 300swm

I'm not sure I buy into the wound-O-matic belief with the 300 WSM. Bullet selection and shot placement are much more critical in killing animals than choosing between 300 win mag and 300 WSM. Plenty of large animals killed with 30-06, and both mags have the edge over that caliber. No one would call a 30-06 a 'wound-o-matic.'
 
Re: 308 to 300wm or 300swm

So whats the difference between a bullet fired from a 30-06, 300 WSM, or 300 WM once it leaves the barrel?

Nothing I can see, its still a .308 bullet at slightly different velocities, which shouldn't be a huge difference. I am just making a point here but a say a WSM has the same velocity at 150yds as the 30-06 at 50yds. The bullet is going to act the exact same both animals.

The animals are the wild card in these stories. I have seen all kinds of different reactions from them after they were shot. I have seen everything from DRT's with a 22lr on deer to taking 5 solid hits with a .338 WM, every animal is different.

Unless the WSM's are leaving a little pixie dust on the bullet making them magical I don't see how it can be a "wound-o-Matic"
 
Re: 308 to 300wm or 300swm

The 300 wsm is no wound-o-matic. I've shot several mulies that dropped dead in their tracks with one shot. I ran 210 grn. Bergers w/ 64.5 grns. of H4831 @ 2732 fps out of Rem. 700 SPS with a 26" barrel. When it comes right down to it, it's all about what you will be using the rifle for and what you want. Good luck!!!
