Pre-64 M70 Re-barrel

dontstrokeme · Posted: Wed Jul 19, 2006 12:24 pm Post subject: Pre-64 M70 Re-barrel

I am looking at rebarreling my Pre-64 Model 70 that is now 30-06. I am thingking on a ERShaw 1.125 blued barrel in 240 Weatherby. I have been told that alot of people like the 257 Roberts, but they only use the 117gr bullets. I would think that the 243 bullet selection would be better. Also the ballistics of the 240 are way mo betta. The cost isn't to bad, I plan to reload them but just curious what some opinions are on a comperable round to the 240 weatherby. Also are the ERShaw barrels good, for the money? $200-$300 is what I want to spend.

Was interested myself in maybe having a 240 built, but after some research I found out that a 6mm-06 is pretty much identical. This way brass would be alot easier to come buy and cheaper also and you would have a beltless case. I haven't decide what I am going to have built yet but if it is a 6mm it will be a 6mm-06.

bubbadoyle makes a good point regarding chamberings in 6mm. The 240 Wby, the 6-284 and the 6-06 have the same case volume. Of these the 6-06 is the most practical IF you are a handloader. Case forming is simple (easiest to neck down is 25-06 brass), brass is available and inexpensive.

dontstrokeme doesn't state the intended useage of the rifle. If for varmints, the 6mm is a good choice, however, chambering in 25-06 certainly extends the ability to take bigger game with the heavier bullets available.

I have installed 3 ER Shaw barrels for guys and they are very pleased with them! you should be pleased as well.
I would consider leaving it in 30/06, Its a fine old cartridge and will collect any game you put the cross hairs on inside its (or your) range. But if you have to have a scorcher, go with the 25/06 AI, Its fast and capable of Bigger game hunting as well as varminting.

Another chip on the fire.
The 240 Weatherby is not an inexpensive proposition as has been stated. You might want to check to make sure that the 06 rails will feed the 240 case, without modification. The 240 is bigger at the belt and smaller at the shoulder. The 6mmx06 wildcat is OK. The 25x06 is also an OK round. The 30-06 as stated will bring home the bacon.

If you want a wildcat, you might consider Mr. Hogdon's (Hogdon Powder Co. founder) favorite cartridge, the 6.5x06. Probably the most popular wildcat today, according to reamer makers and reamer renters, is the 6.5x06. It did not get to that spot by accident. It will do everything the 243s, 257s and 270s will do, without much problem. The ticket for the 6.5 barrel is a 1-8 twist. This cat is so popular that a few companies are making the 6.5x06 brass, with a headstamp, so it might be considered a cat that isn't.

Take a look at the reloading data sites and compare the numbers before you decide. I have included a few sites for you.

A chuck shot at 100-200 with an 85 Sierra FBHP at 3,755 fps is something pretty special to see. A deer, chest shot, at 100-200 with a 140 Interlock at 3,000 fps, is amazing, it purees everything from the esophogas to the diaphram, blowing a large spray area out the back. In both instances you get two reports from the shot, sort of a boom-boom sound. The second report is the impact!

I have had a 6.5x06 around (3) since 1969. It is just a gun I pick up when someone says let's go shoot xyz and it might be a tough shot, etc. By the by, if you get a 26 inch barrel and your buddy has a 24 inch, 264 Win mag, you have him on the hip. The killing effect of a 6.5 bullet is way beyond its paper numbers and .25 to .5 groups are very common.

not wanting to cause a issue but why do people even want a gun that turns a deer into one big bloodshot mess at 200 yards.

now if you were shooting 600 yards i can see maybe wanting 3000 fps for deer.

i prefer my deer gun to be adequate for deer at 300 yards with no bloodshotting.

a 30 06 with some rounds is just to much at 200 yard ranges. you cant shoot a deer with one of the new ballistic tip bullets at 100 yards because if you hit the ribs you ruin the ribs and tenderloins from blood shot.

i watched a friend 2 years ago shoot a 200 lb 8 point buck at 100 yards with a 125 grain {i think} ballistic tip dead center in the left rib cage the spray from the other side looked like a fire hose. i went to dress it for him and as i skinned it i just wanted to cry.

both ribcages bloodshot completely. no saveable tenderloins left at all. the only meat he got was the hind legs.

to much gun is as bad or worse than to little gun.

I was thinking more along the lines of an accurate longrange rifle more than a hunting rifle. With the 1.125 inch barrel I would not be packing it much. By the by how is the recoil of the 240 Weatherby?

Spacedome,
Ok, now I am mad... Smile

But, you are assuming something to be true, that isn't true, in the case I recalled. There was no damage to the tenderloin and the effected area was about softball size on both sides, about normal.

Come to think of it, my 444 Marlin with a 240 not only liquifys the chest cavity, the cavity is totaly clean, like it was vacumed. The bullet blows everything out the back. no damage to the tenderloin, either.

My point was you do not have to go looking for the deer, all over creation, he is right where you shot him. Just a bit more colorful way of saying it. Very Happy

if you hit the deer in the sweet spots ie head neck or heart/lung area at 200 yards a old lever action thirty thirty is more than enough gun.

the point is what i watched my friend do actually happened. out of a 200 pound deer he got less than 30 pounds of meat.

i also know several people who deer hunt in areas where a long shot is 100 yards using 300 win mags.

heck my 303 hand loads of 150 grain interlocks last year i shot a spike in the hind quarter and as it came out destroyed one whole hind leg {only hit the behind and killed it dead on the spot}

shot placement is whats important not what you shoot it with.

as a child i saw more deer killed with 22 head shots than deer rifles.

a hunter should use a adequate gun to take the game hes hunting humainly. not being to small a caliber or to huge a caliber. you dont want to kill deer with a 22 nor do you want to use a 50 bmg at 20 yards.

hunters get a bad enough rep just legally hunting without we the hunters doing things that are just plain silly.

just because you can do something doesnt mean you should do something.

I have collected a few deer with the ol "06" and have had no blood shot tenderloin, a few shots were taken at under 200yds and a few at WELL under 100, no bloodshot meat.

dontstrokeme: the recoil is exactly the same as the 6-284 or 6-06 as the powder capacity of the three cartridges is, for all practical purposes, identical. IOW, rifles chambered in any of these cartridges that are equal in design and weight will be equal in recoil with equal velocities and equal bullets. More directly, recoil is less than a 25-06 and slightly more than a 243Win.

Three years ago we chambered a rifle in 6mm Ackley (the 6mm Remington in its improved version) as we wanted to use a medium length action, in this case a Sako. The Krieger barrel is 25" and it delivers the 100gr Noslers @ 3,210fps with no pressure signs. I mention this because I believe this is a better option than the other 6s we have been discussing due to its efficiency. It may warrant consideration for your intent of long distance shooting and it is much kinder to the barrel than the 6-284 that I have. However . . .

If long distance accuracy shooting is the name of the game, one of the outstanding cartridges is the 6.5-284. So much so, in fact, that brass is factory available.

Can this also be rebarreled to .257 Weatherby? I've read that the .257 Weatherby was Roys favorite of all his chamberings. Seems like a scorcher of a rifle with a 115 gr. Barnes Triple Shock, and Nosler has 115 & 120 gr. Partitions.

My main reason for not picking the 257 Roberts, 257 Weatherby, 25-06 was the low selection of the .25 bullets. Far less available than the .243.

Thanks for the input though.
