30-06 long range Model 70 target

Hello all,

I've lucked into a 1970 Winchester Model 70 target with the marksman stock chambered in 30-06 (26" barrel). I'm wanting to use this gun a long range target/ hunting rifle. My initial thought was:
208 grain Amax
Reloader 17 or H4350
Winchester Brass
or
190 berger hunting VLD
H4350
winchester brass.

The rifle will be used as 95% target 5% hunting. Will the Amax be too heavy to see advantages above the 175-190 berger hunting VLD? My target velocity would be around 2700 I think. I notice German Salazar really doesn't go much above 200 grains; but he is shooting iron sights and is concerned with recoil.

share with me your experiences shooting the 30-06 beyond 500yds

112- all my experience with the 30-06 is with a garand. German's experience is the most relevant i know of. awesome round. i wish i had lucked into one of those. i haved a 210 berger but that is out of a 300 wm. i am shure you are on the right track. roninflag

If your shooting mostly targets I would try the 215 hybrids if your twist rate will allow it. I think that the 7 grains of weight would be worth the b.c jump, you might not even lose that much M.V due to short bearing surface. Other than that I would drop to 190's.

I don't own an 06' so take it for what its worth, .

Re: 30-06 long range Model 70 target

I've owned a couple and shot more of Winchester's Model 70 target rifles. They are pretty good out of the box, but have one common issue. The groove diameters in them are a bit on the big size. Both the pre-'64 broach cut and post-'64 hammer forged ones. With groove diameters of .3082" to .3085", best accuracy has been with bullets at least .3086" diameter or bigger. None of them shot heavy Sierra Match King bullets at .3082" all that well. With .3092" diameter Lapua's they did great.

If you can find some good bullets at least .3085" diameter, you'll get best accuracy. Sierra's 155-gr. Palma bullets used to be .3084" but I don't know what they are these days. If bullet making companies will tell you exactly the diameters their heavy bullets are made to, that'll help. Otherwise, you'll have to take a good micrometer to the retailer and get permission to measure some.

All Model 70 .30-06 factory target barrels had a 1:10 twist. Perfect for 190 grain bullets through 220 grain bullets at the speed max loads shoot them at. A match winning and record setting load back in its day with custom match barrels was 56 grains of IMR4350 under a Sierra 200 grain Match King bullet.

Re: 30-06 long range Model 70 target

Bart,
Thanks for the great info and first hand experience. I'm headed to the store today since the gun show this weekend had no dies, powder, or bullets. I hope they have some heavies. I'm thinking of loading today and then shooting sometime next week if all things work out.

Re: 30-06 long range Model 70 target

So with components in short supply; I ended up buying Reloader 17 instead of H4350. yesterday I necksized the Lapua brass and loaded as follows:

Berger 190 Hunting VLD
CCi BR2 primer
0.003" neck tension
3.34" COAL
51 grains to 54 grains in 0.5 grain increments. Reloader 17

The Berger book doesn't have RL17 for the 190VLD so I extrapolated from Alliant's website. The low end is for a 200 grain Speer SP and the high end is from a 180 grain Speer SP.

My question now becomes, am I going to find appropriate velocity with these powder weights? Does anyone have experience with this combination? I can't find much definitive data with 190 VLD's and RL 17 in the 30-06.

Bump to the top.

As an aside I sighted in the Weaver 24X with this rifle recently. I broke in the gun cleaning every shot for the first 5 shots. The last 3 shots hit dead center bull with a horizontal pattern of about 0.5". This was using factory Winchester Super X 180 grain SP's.

I'm pretty excited with this rifle.
as a side note, the rail underneath the forearm will not accept the same bipod/sling adapter that my 112 savage BT uses. I guess its just bags and a front rest for me.
