Weight of #3 sporter contours shows notable difference
between the two brands. If anything, I imagined Krieger would be slightly heavier (based on given dimensions), yet Shilen quotes almost 1/2lb heavier.
Which is the more accurate figure?

Idea is to implant 23".630-.640muzzle 7x57 tube on M70sa with McmillanEdge(23oz) or lighter BrownKevlarPounder' or Lexwebernick 13oz unit(maybe too light). What is required is approx 8lb(+/-,1/4lb) all up scoped rifle, somewhat, but not overly, muzzle heavy for steadier shots. Happy with the basic WSM profile but tapered out to .630-.640"muzzle@23".Even a little longer(.610@25") would be fine.
Final weight of that tube would determine which stock weight to use.We dont want it overly muzzle heavy, if you know what I mean.

look carefully at all of the numbers-the Shilen is a larger blank overall. I imagine both weights given are pretty close. As for the difference between brands, each maker picks its own dimensions and names them whatever they want. A "#3" is not a universal measurement, but is an arbitrary name given by the maker.

It is about like some people calling their wood "AAA" or "Exibition" or whatever-they just call it whatever they want to.

I would be surprized if you could come in at 8lbs scoped with a #3 contour barrel. I would step down at least one.

I'd think twice about anything over .600 for a 7 x 57. Im stuck with a .650 on a .300 winnie and its too much. it will be way to much on a 7 x 57 IMHO.

yup....everyone to their own but a 7 X 57 barrel coming to this house has a muzzle diameter of about .550.

vapodog is spot on about the max daimeter for a 7x57. Personaly i like .575 muzzle diameter for a 7x57.

I have a Shilen #3 in 7x57 on a Mauser. That barrel is HEAVY. A #2 or even lighter would be my choice for a sporter 7x57.

woodjack,ive got one sheilen and 2 kreigers i''d rate kreiger a 10plus the sheilen a strong 9, your choice a # 3 will be heavyer but it will point and hold better imho, heat up slower and sustain groups longer before walking its shots, your in the ball park friend regards and keep us posted ...jjmp

Thanks for d input guys.

TC1,... 8lb is easy done.

M70sa................2.5lb
#3 tube..............3.0lb
McEdge...............1.5lb
2.5-8x/mount......1.0lb = 8.0lb
Even less, if we cut her down to 23" and fit one of the lighter stock options.

I am not totally sure how it would feel at the muzzle, but a rem700LVsyn22/250 has a fluted .657@22" and it feels OK(6.75lb bare). Although the win70sa will be little heavier(5oz?) in the reciever.But could overcome that by fitting the Brown Pounder instead of the McEdge.
I do feel now however than running the #3 to 25" may make things a little too heavy in the muzzle. If limited to 23" it should be reasonably fine...we hope

To get most weight off I would shorten the barrels shank (D section) to 1 inch or maybe less(did this on my 7mm mag) it will result in more weight reduction than cutting of a few inches in the muzzle. For a 7X57, 270, 7X64, 3006 etc a contour # 1-2 will be fine. Shilen specifies weight at G length, in this case 26 inches.

I think shilen barrel contour # 3 is suitable for magnums. up to 9,3-375 etc.

you also might be able to steal a few ounces if you shorten the shank length. Shilen has their standard at 2.5" and Krieger goes 2.75"

and it depends on what the maker is quating as the "standard" caliber for weight. iirc, shilen uses a .308 ...

makes a huge difference in weight.

an 8# wood stocked rifle with a #3 in less than .358 can be tough

Have you ever spent any time with a Winchester Classic LT or Super Grade in a magnum caliber? The barrel contour on these are almost identical to a Shilen #3 and most are only 24" long barrels. My .300H&H started life out as a 7 Mag 24" barreled rifle and was closer to 8lb without optics than 7 1/2lb it was advertised at. Now mine didn't have a 1.5lb stock on it, but I can only imagine if the stock saves that much weight it would only mess up the balance of the gun.

Best of luck.

Tc1,
Have had a 30/06 24" M70classicSS 1.5-5x 8.25lb,.338win 26"ClassicSS4.5-14x 9.0lb.
At present have M70ss 22/250,2.5-8x,8.25lb),and 300winClassic Stainless 4.5-14x,9.25lb
The .300&338 magnums have .580"@26" ,factory barrel measure.
A winchester factory tupperware stock weighs about 2lb Sa&La.They use the same stock,same outside dimensions.
I believe the 30/06 24" contour is the same as the 24"WSM countour, .580@24"??

I remember chasing a boar for 200+yd through some trees with that M70-06 at 8.25 lb, I finally had to take shot,and it did not offer me the steadyness I desired. I have also had a 270Weathmag@24"MkVFactory tube,that had Brownglass stock 8.25lb,that I had to run with for 500+yds to head a boar off,It didnt offer me the reasonable steadiness I wanted either.I felt there was too much weight in the reciever and not enough in the barrel.
Hence, I want something compressed in length,heavier in the barrel,but generally no less or more in total weight. If that makes sense. It seems that about a .630-23" on an M70Sa may do that. But I suppose everything is trial and error to some degree.
Another option would be to stick with the basic WSM barrel measures and just fit a heavier scope.A leupold 4.5-14x40LR(30mm)DDlowrings,front extension base, fits very well on M70sa. Distance between rings is about 142 mm, tube about 150mm,just enough to clear the rear step of the rear base.
The 4.5-14xLR fits very nicely on M70La also, with normal DD setup.

My 7x57 built by a friend ( Clayton Nelson ) weighs in at 8# exactly on my bathroom scales which is all I have to weigh by. It's a 1909 with custom bases Ironsights and barrel mounted swivel base. Barrel is .548 at muzzle and is 22". Douglas premium I believe as I didn't specify brand of barrel. Wood is really nice piece of DARK french with Niedner buttplate and cap, ebony tip. Scope is a Leupold Vari X-II 3-9 in Talley rings. Timney trigger. Shoots like gangbusters especially 175gr Nosler Partitions. It was my plains game rifle on my last trip to Zim and had no trouble with Kudu out to 250 yds. Absolutely one of my favorite guns. Only Custom I have ever commissioned for myself. Most of what I have I built.
