.308
 

Hi, i was wondering if any you guys have remington 700 sps varmit rifle in a .308 cause i am consering own buying one but the 12'' twist own the barrel got me confused if it made to shoot light or heavy bullets at the end the barrel?

RE: .308
 

I have a Remington 700 Varmint Synthetic .308 and shoot Hornady Light Magnum 150gr. SST and have had great results. The ballistics are just under a .300 Mag.

RE: .308
 

Let's compare apples to apples. To say a 308's ballistics are just under a 300 winmag isn't accurate. About the only way your going to consistantly get above 3000 fps with a 308 is if your running some pretty hot loads. The 300 winmag is right around 300 fps faster with every bullet weight when staying withing saami limits on pressures.

The .308 can be a fun caliber. I have had my gunsmith make up a load for me (I don't reload) with a 55gr bullet that performed well. I honestly do not know if a 1 in 12 twist is "designed" for something this small though.

RE: .308
 

Isn't the slower twist designed for the heavier bullets? Or do I have it reversed? I would shoot either 150's or 165's in the 308 anyway.

RE: .308
 

Heavier bullets require faster twist rates to stabilize.
Too slow of a twist will result in yawing and pitching during flight, and will be manifested as poor groupings and keyhole shaped tears.

Lighter bullets need a slower twist rate.
Too fast and the bullets will weaken, deform,or get torn apart, sometimes resulting in core/jacket separation in flight if the mismatch is extreme.

I rememberthe relationshipwith a bowling analogy...
You have to put a lot of spin on the heavier balls to get themhooking where you want them consistently. Although we aren't trying to 'hook' bullets, I've never forgotten which way it works.

Having never reloaded or competed with a 308, I can't say I know which rate is optimum for the different weights available in the caliber.

RE: .308
 

Twist rate of 1:12 is in the middle of the pack. Should handle 165 gr. +/- bullets at typical muzzle velocities just fine. However though the 308 Win. is my hunting cartridge of choice, I am no expert on internal (or external for that matter) ballistics.For a good treatise on the 308 Win., I suggest you search on "308 Winchester Cartridge Guide". This is a nice compact article on the 308 WIn. written a few years ago.

RE: .308
 

What bullet weight would be best for a 1:10 twist in a Browning BAR MK II Safari .270, Winchester XP3 130gr. or 150gr.?

RE: .308
 

I find the 165gr to be a tack driver in the .308 cal. You'll surely be happy with the purchase of a Remington 700 varmit. I do have to agree though with thndrchiken's post though. The .308 and .300 aren't even in the same catagory. Good luck with your decision.

This might help. It's a Caliber Twist Rate Chart.

RE: .308
 

the perfect weight for a 308 bullet is 165 grains (exception is x bullets) this has the best ballistic coefficient for a 30 caliber bullet. bigger the bullet the slower the twist i believe.

RE: .308
 

why would you want a .308 for varmit hunting when there are lots of .22 and .243's to hunt with. the 22.50 and .204 ruger make fantastic varmit calibers.

RE: .308
 

I purchased this gun earlier this year and topped it with a burris 4x16x44 mm signiature sellect scope.

Not becauseI wanted it for varmnint hunting, but because I wanted a .308 with a bull barrell.
The .308 700 varmint comes with a26" bull barrell, neat stock with a flattened fore stock, drop floor plate (no clip).

To dateI have tried-
Federal Fusion 150 gr.= no go.
Winchester supreme BT 150= no go.
Remington Corelokt 150- Go. (last time out right under 1" with 3 shots).

Funny thing is I broker the barrell in with the "cheaper" Core Lokts and things were going well. When I switched to the higher end bullets (they cost more anyways) the groups suffered. I went back to cheap and my groups shrunk once again.

If I had more time and ammo money I'd step up to the 165's to see what they do. But season is closing in too fast to be playing at the gun range.

RE: .308
 

The .308 is a great round, and yes, shooting Hornady light mag ammo helps it . ( I shoot the light mag ammo too ) but it is not fully equal to a .300 mag . To get close to that, you would have to have a 30.06 with light mag ammo. or a 7mm mag with light mag ammo.

But the 1 in 12 rate will do great with a 150 gr. and even better with a 165 gr. But if the 165 gr. is unnecessary, then you will get all the accuracy you need from the 150 gr.

The .308 is an inherently accurate gun. My .308 is the most accurate gun I own, and I own a lot of guns. Mine is a Ruger M77 Mark II stainless / synthetic .308. It has a 5-20 x 44 Nikon Monarch SF scope on it , and it is da bomb..... It is a fine short or long range gun combo.

Well, I hope and pray that my ramblings have not confused you. But the .308 is good enough to take most North American game cleanly..... that has to count for something.

Federal Match King BTHP 168 gr = Top of the line round for your 308 & that's the bottom line!
