30 cal questions .........

Im looking for a new target rifle and am focusing on a heavy barreled 30-06. Then I got thinking about the Sendero model 300 UM, or a Heavy WSM. Is there anything that any one of these rounds can do that the other cant? Besides speed, would there be any advantage to going to a harder recoiling flatter shooting rig if the range will be set? Thanks for your thoughts.

Re: 30 cal questions .........

MSU-Marksman,

Target shooting's primary goal is utmost accuracy. A proven cartridge such as the .308 Win is one of the best around for that purpose. A flatter (faster) shooting cartridge is less affected by wind but it also recoils more and is therefore more difficult to hold for utmost accuracy. The fact that it drops less is of no consequence because, as you say, the range is set and set accurately. How hard the bullet hits the paper is also a moot point as they will all easily punch a hole through it!

Another factor to consider with target shooting is the amount of shooting you will do during a single session. Recoil has an accumulative effect and you don't want a hard kicker that will hinder your accuracy and enjoyment as the shooting progresses. An excellent article by Bruce Gray, "Hit at 1,000: Zen and the art of long-range tactical competition" would be of great help to you. It appeared in the Jan/Feb 2004 issue of Rifleshooter. It is extremely informative. Enjoy! [img]images/icons/smile.gif[/img]

Marksman, just so you know the .30-06 isn't the most accurate .30 you can get. I would recommend a .300 Win Mag. That way you have a highly accurate target rifle out to abou 1200 yards and you can use Lapua brass. As far as the WSM it depends on how long a barrel you want. The WSM will only do you any good with shorter barrel like a 24." How far out do you want to shoot? There is always the trade off between faster rounds and barrel life. Its just the price of performance and how important going far is to you.

Re: 30 cal questions .........

Look over the rules of the class you are shooting in. If ranges are moderate to say 600yds, then the 308 is the ideal choice. If you are going further or can choose any caliber, there is little reason to use the 30cals even out to 1000yds.

My guess is that there is limit to rifle weight like 16lbs or whatever. Unless, you can use muzzle brakes or build 40lb monsters, the heavy bullet 30cal that do work wonderfully, will beat you to a pulp in one session.

Target shooting is about hitting a target not how much abuse you can tolerate. Recoil will reduce your ability to shoot well, that is why smaller is better.

For moderate ranges, the 6BR or 260 will be ideal. Only shoot a 30cal if the rules mandate it, then the smallest case you can get away with and still launch the highest BC bullets.

Re: 30 cal questions .........

Ironically, the only two other centerfire rifles I own are a 6mmbr and a 260. The reason Im considering a larger caliber is that I like knowing I have to potential to bring the downrange energy to hunt with also. Besides that, I own a garand and just love that 30-06 round for natalgic reasons. Thanks for everyones input.

Re: 30 cal questions .........

30.06 in a modern rifle without military /machine gun chambering ( with a lot of respect for the 1903 and M1A.. ) and load at 308 WIN pressure level can deliver velocity close to light 300 win mag

accuracy is very good , the short action /shortcase fashion ,and 308 avaibility have with time make the 30.06 less popular BUT that still stay a great cartridge just need a good chamber design with tighter base and match throat

in other great cartridge classic 300 Wea is not to bad with match chambering

good shooting

Re: 30 cal questions .........

MSU, I have hunted with 303 or 30 cals so I understand your feeling. I have a very soft spot for the '06. wonderful at 'normal' hunting ranges.

For me, wind is my biggest enemy. At ranges beyond 300yds, the mid weight 30cal bullets are not very aerodynamic. My solution was to go to the Gibbs. A great fun wildcat (performance similar to the WSM/RSAUM). Unfortunately, still not the best at bucking wind at mod long ranges.

Recently built a 6.5-06 and shoot 140gr SST. WOW, what a difference. hits as hard or harder because the bullets have such a high BC and SD, they simply slow down less. The dents on my gongs are significantly bigger and deeper then with my 30-06 and 165gr SST. Wind drift is about 1/2.

For ranges out to 600yds, I am happier with the 6.5-06. They both have enough energy for deer but if you can't hit the animal, what's the point?

I am now working on a 270 and 150gr SST simply because I want my hunting rifles to use off the shelf cartridges. I will be able to get 270 ammo anywhere in North America. Ballistics should be very similar to the 6.5-06.

If you feel that the 30cal is the way to go, then I would lean towards the WSM or win mag as a min if you want to go to ranges beyond 300yds. With a 178 or 180gr SST or BT, should work very well and buck the wind adequately. The '06 is simply too small to deliver the vel.
