How will the 175 mk do as a hunting bullet? I also shot some factory Nosler 165gr Accubond and had 2 touching and one just off. This rifle is fun to shoot.

I just recieved the load data from Berger so I will work up the loads for the 168's this weekend.

Thanks for pointing me in the right direction

Personally, I dont like the SMK's for hunting. They seem inconsistent to me in the terminal department. I prefer the AMAX variety except for the 155. From the 168 through 208, the terminal effects at long range for up to deer size critters has been flawless. I wouldnt use them on anything bigger than deer with the exception of the 208. I would feel safe using that for elk SO LONG AS I took ony lung shots and NO bone. The good choice for elk and larger is the 200 SGK. Good weight, good BC, good construction for 308 velocities and a great minimal velcoity for expansion. Bergers are great and all but require a higher velocity for expansion. (1800 FPS versus 1500 FPS)

My answer to this is. The only reason is to make the 7 RM look good. There is no other reason.

Re: Making A Case For The 308 Winchester By Michael Eichelle

I have become the owner of a Remington 673 in 308, new, only fired at factory, this is the second one I have owned in the last 6 months, the first one was a disaster. It has a 22" barrel, what can I do make it a decent 500 yard gun?

Re: Making A Case For The 308 Winchester By Michael Eichelle

Why was the first one a disaster?

What is your definition of a decent 500 yard gun? Paper, varmints, deer, what???

Re: Making A Case For The 308 Winchester By Michael Eichelle

Great article Michael Eichelle, and a lot of useful information regarding the application of the 308, ballistics, velocity, potential loads, and use of various grain bullets. I've been lucky enough to shoot moose out to 400 + yards with a 30-06 220 grain bullet and over 600 yards with a 300 WM 180 grain bullet. Terminal on both of my first shots on the animals. Admittedly, Both times were simply guesses at best. Naturally, like most hunters here, quite a few have been taken at more do-able yardages inside 300 yards. And the Canadian moose is a large enough target so those are my best achievements. The only thing that offers any kind of explaniation for these great shots is based on tthe fact that I have shot a lot of smaller caliber rifles and somehow, through trial and error, have learned to "arch" the bullet to the target.

What I have noticed in your article is that there is a far more precise science to your successful shooting application(s) at Longer distances then i imagined there were. I'd say, overall, it all makes sense to me. I've been reluctant to get into hand-loads and have dialed in all of my hunting rifles with factory loads that have proven to shoot as good as they can within a 300 yard average. I now see that re-loading can make things much more accurate out to yardages beyond 300 yards.

I have been looking around at mostly factory rifles that seem to have some long range capacity, and as a left hand shooter the options are limited. In relation to less expensive options I have two in mind that I would like your comments on.

I see long range shooting as my next step in hunting...

1. If choosen I would have to purchase Savage 10FLCP-K 308 with accu trigger and accu stock, detachable mag., Carbon Steel 24" barrel; 1 in 10" twist; factory muzzle brake and factory weight without scope is about 8.9 lbs. This is probably a starting point for something that is set-up at the factory in 308. But given it's deminsions, I'm not too sure what it's limitations might be. I've always preferred heavier bullets and would appreciate any comments you may have...? And I don't know if Savage would install a longer barrel as a request.

2. I do have a Left hand Savage 16 FLHSS in 300 WSM; 1 in 10" twist and a 24 inch barrel, the factory weight without scope is 7.15 lbs. I could look at a longer barrel. At the present time it shoots Federal 180 SP quite well. any comments would be useful.

As an asside, once I found out that my Sako 30-06 shot the SGKBT 165s with amazing accuracy I have never tried anything else. But I don't know the extent of yardage with this rifle and cartridge.

Thank you.

I have never had any trouble running 200 grain pills in the 308. I prefer the SGK. They are a bit shorter than the Accubonds and open up at lower velocities. This is a good choice for elk, moose and bears. The BC's are very close as well.

For deer and sheep I like the 168, 178 and the 208 AMAX. I prefer the 208. The 208 I am running at just over 2600 FPS and is deadly accurate way out there. With its high BC, it offers minimal wind drift. Windage of the 308 has long been the largest complaint among shooters for years next to bullet drop. With the advent and availability of the laser range finder, the drop has all but been forgotton but not the windage.

The 208 has made a dramatic improvement in the 308s windage department. I had been concidering switching to the 7mm08 a while back due to the 162 AMAX and 168 Bergers. After testing the 208, the windage is neck and neck. Granted, there is a bit more recoil with the 208 versus the 162 however with all trade off's there are certain advantages and disadvantages. The disadvantage is the recoil. The advantages are barrel life, down range energy, a bigger hole and a lot more material to be shed inside the critter. It is a legitimate 1000 foot pounds at 1000 yards load. Add 5000' of elevation on a deer or sheep hunt and it becomes over 1200 foot pounds of energy. This is a contender for a 1K deer/antelope/sheep load and definately a legitimate 800 yard load with 1500 foot pounds.

With RL17 or VV N-550, you should have no trouble finding 2600-2630 FPS in a 24" stick. You may have to load them 1 at a time. I personally dont like to do that. I use a Wyatt box magazine (extended length) and use N550. It takes a bit less powder to reach 2600 and it is a smaller size which takes up less case capacity. I can seat the bullets for magazine feeding without any trouble.

The first one had bad riflings, apparently it was a refect that slipped by quality control, it took about 6 months to get another rifle. I refused to let them change just the barrel. Remington finally agreed.

I want the 500 yard for deer and elk, I have never had a 308 until I bought the first one, do not know that much about them. I have bedded it, replaced the factory rings and bases on the scope, removed the raised rib, installed a Timiney trigger, had the bolt checked for true. I put a 4x12-42 Nikon Monarch on it. Any other suggestions would be appreciated.
