270 Wby MKV Deluxe 1960 German
« on: May 14, 2024, 08:44:24 AM »
The rifle is a pristine (clean) MKV Deluxe 270 Wby manufactured in 1960 with a 24", #1 contour barrel, 1:12 twist with a 3x9 Weatherby Supreme Scope. Trigger is set at 2.1 lb. Nice to look at but here is the problem, I'm having a hell of a time removing a considerable amount of built up carbon (time and elbow grease will get it out). The throat looks like it is at .050 wear and the rifle should have a .035 free-bore according to Weatherby and was designed to shoot 1.5 MOA new. I like the fact its a 24", #1 contour barrel and like to have the barrel changed. So here is the dilemma, Weatherby can only install a 26", #2 contour barrel and if they did that the stock has to be replaced. I like the rifle the way it is so question to the Weatherby experts, is there a manufacture that sells a #1 contour, with a high gloss finish? Appreciate the help. Thank you

Have you shot it yet? Before spending a bunch of money,check it out for accuracy. Having a 1 in 12 270WBY myself,it will only stabalize 130gr. lead based bullets and is at it's best with 110gr Barnes. Anything heavier won't work. I have tried. Finding loaded ammo it will use is almost impossible. I load my own.  :)

FYI, It was not designed to shoot 1.5 minute of angle.It was guaranteed to shoot at least 1.5 MOA.

I would get the bore cleaned up and try some factory ammo in it.You might be surprised how good it does shoot. Evidently it's not that bad,because it's been around,evidently shot well,or wouldn't have build up,and it hasn't been altered for 63 years.

I would definitely change the scope out.The only thing you have to lose is the cost of a box of shells.I've also seen 1 in 12 twist 270's be tack drivers with 150 grain Partitions too,so you never know until you try.Every rifle is different.

No I have not shot it yet as I am trying to clean the bore before I start my load development. Weatherby did inform me not to go higher than 130 Grain bullets so I have supplies to accommodate the rifle. I own several and only two I had not changed barrels because of throat wear the 340 and 300 Wbys. But just getting prepared in case this jewel doesn't shoot with my developed loads.

Quoting the Nosler manual, "Weatherby rifles of German manufacture(Pre 1972) may have barrels with a 1 in 12 twist rate.These rifles may not reliably stabalize bullets heavier than 130 grains. "    ;D

Have to agree with you, Ill look into Berger or hammers and see if they do well.

Berger manual says 1 in 11 or faster for their lightest 140gr bullet! Barnes says the 110 gr is as fast as they reccomend for the 1 in 12.  The 130gr. A-Frame with H1000 works well for me.

Never know unless you try the 150 Partitions.

I had a 1in 12 twist 257 Magnum that loved the 117 grain Sierra boat tail.Really long bullet.They weren't supposed to work with my slow twist either.

Just because someone else says it won't do this or it won't do that doesn't mean jack.

I know exactly what my 1 in 12 will and won't do. Apparently, so do the books I qouted and Weatherby. Oops!  ;D

You're getting sloppy.You forgot to tell us,for the 1500th time,that it's the 32nd one made.

I got some ocean front property in Oklahoma that will make you rich if you can hang onto it for a couple months

purchased an old 270, man she was dirty dirty - man i scrubbed and scrubbed till that old sucker was squeaky clean. Couple of fowlers with bore sighting new scope and next thing you know this sucker shoots under an inch. LOaded some 130 scirocco's and shoots half an inch gun all the time;
