Ummm Ya, Actions

Just curious, has anyone been able to play with Weatherby Mark V 338-378 Wby. Mag.?

[Broz]

A Weatherby Mark V stainless action was used to build my .338 Lapua Mag. The more I use this rifle the more I am completely satisfied with the build. Here is why, with some facts that may be of interest if you are thinking of building one.

I use H-1000 and CCI 250's under 300 SMK's. I get velocity over 2850 with room in the case for more. No sign of pressure. Not even the slightest of crater on the primer. I just reloaded the first 100 cases I started with for the 7th time. Every single primer pressed in firmly and every one felt the same going in. I have trimmed the cases 3 times durring this time, once when new. I have bumped the shoulder back twice and just a slight bump. I do anneal the necks but most of the time a cleaning and a neck size would be good to go. With the 7th time reloaded my worst runout checked at the O give of the bullet was .002". That is total RO, so .001 each way. I have taken much game with this rifle at extended ranges. Here are the 3 farthest, Antelope at 820, WT deer at 1137, and a Bull elk at 1130 yards. All DRT.

Two weeks ago, I stopped by the range. Took out 3 rounds, ranged the steel plate at 1007 yards, entered the conditions and range in the pda. Dialed up 24.25 moa. and left 3/4 moa for spin drift. Then off my Harris 9-13" bipod fired the 3 rounds. Went to the target and I had a 4 1/2 " group. I was very happy. Today I stopped by the range again. I had since cleaned the rifle. I did the same proceedure. These 3 were in the same group as the last 3 from 2 weeks ago. Six shots, two cold bore, 4 follow ups inside 4 1/2 inches at 1007 yards.

Maybe I am just easy to please but the 338 LM has earned my respect.
Sorry for the long post but I tend to jabber when I get around a pretty girl or a good shooting rifle..

Good luck with your build.

Thats what I like to hear. Did you buy the action stand-alone or did you part out an old rifle?

I am sure it was from a doner rifle. Here are a few pics. It is the nearest one.

In a Rem action I would look at the 338 Norma. The Lapua bolt face is not a problem, but with a 300 smk seated where it should be you are left with one ong ass cartridge. The Norma is designed for the Rem and a 300 smk and seated where it belongs OAL is 3.6"

+1 on the 338 norma. The lapua can also be done on the 700. I have seen hundreds of them and they work just fine. I have talked to Shawn Carlock and others.

Broz, nice couple of rigs you have there.
