Forgive any typos, and rambling I just had spinal surgery and you guys are the only ones who want to talk rifles right now......

Back around 1971 I was givin my first center fire rifle. A DWM made M/98 Mauser in 7x57mm. A short 1935 style Brazilian cavalry carbine actually.

Around 1973 it became the basis of my first suscessful sporter conversion.
I spent an entire winter carving out a solid block of english walnut that I bought from Herters. The barrel was a Douglas blank tapered to a #5 contour and used a 1 in 10 twist. Again in 7 x57mm Mauser. I put in a Timney trigger, and glass bedded the entire action and barrel after I discovered that I had sanded away too much wood in the barrel channel.
For a scope, I bought a new Weaver 2x 7 power made of steel. I got that through the hardware store where I worked part time.


Back then, Turkey shoots were a big deal around here. No TV and we actually had reloading as a high school class. And this rifle helped me win three or four turkeys per year. Not to mention a bunch of side bets.

I harvested every game animal in North America except Buffalo with this rifle as I went off to college and eventually traveled around much more with Uncle Sam.

After many thousands of rounds, she became much less accurate using the old handloads that had served me so well for these many years.
So , she worked her way to the back of the closet. Being much more heavy than a hunting rifle should be, a little less powerfull than others and now loosing her reputation for pin-point accuarcy. Even her scope was now yellow tinted with age.

Recently I had purchased three or four high dollar rifles that were supposed to be accurate right out of the box. None of them were. Particularly the $1,800 Remington tactial rifle.
As I am mentoring a couple new shooters, I kept mentioning how a real rifle would shoot when properly loaded. Most of these conversations turned back to my old custom Mauser. Lizzy Borden..as in gave her father 40 whacks..

In an effort to prove my point, I started on a two day barrel cleaning using copper solvent and JB compound to see if I could help clear up the bore in that old Mauser.

Then I retorqued all the stock bolts again.

She was still a better rifle than most any out of the box guns, but she would not shoot her old standby handloads as well as she used to do with new rifling.

So I tried some loads from my old hand-loading log book that I had tried 35 years ago. At the time they were were ok but not outstanding.

On a lark, I even assembled some loads using all 1970s vintage components. Including the bottom part of a pound of Dupont IMR 4831. This can was opened and mostly used in the mid 1970s. It has not been stored under ideal conditions.
The 70s vintage Hornady 162 grain National Match bullets were so nasty looking that I had to use steel wool on them.
The primers were old CCI-200s that were wrapped in tape back in the 70s when I was transferred to a new military station.
Even the Winchester brass was old and had been fired about 8 times.

Here are the results, an old dog can learn new tricks! I think the Norma Steel jacket bullets made two little groups because I was getting up to write down the chronograph results. I was very sunny against the snow so the chrony readings made be off. Only a few registered at all.

Here she is with the original 1970s finish still on her. I used hand rubbed Carnuba wax and lemon oil. The thumb-hole part of the stock fit my hand back when I was 16 years old and weighed 155 pounds. (and I was 6ft '2" back then.) Now that I am around 210 lbs, my hand has a tight fit.

Basically this rifle will no longer shoot the loads that she loved back 35 years ago, but she is doing ok with other loads now, So the change in rifling depth and sharpness can be compensated for to some degree by handloading and cleaning the heck out of the bore.

That is truly an outstanding tale, and great rifle....thanks for sharing that. Glad to see that the ol girl has still got it - she just wanted some pampering and a change of diet! Truly awesome groups! Dang, they don't make 'em like they used to. :D

we actually had reloading as a high school class.
:eek: Wow, that was before my time - I'm speechless at that - I sure missed out; why must our generation get shafted?

The only question that remains is WHEN is the trip going to be scheduled to some private ranch where you can *finally* harvest that American Bison with her, to run the table on N.A. game? (in a fair chase or at least semi-fair-chase hunt on a very large ranch, mind you).
 
Have you tried experimenting with seating depth? Maybe you have throat erosion, and getting the bullets a little closer to the current origin of the rifling might help.
 
FP, hope the surgery recovery goes well and swiftly.
Safe to assume 100 yds on those teeny tiny groups?

Yeap, 100 yards from sand bags. That old Weaver scope is kinda hazy.

Vern, I played with the seating depths and it helped, You can see my load info on the photos and seating depth has become pretty important as of late.


Those old Norma steel jackets rounds are really something. I won them at a turkey shoot in Anchor Point, Alaska back in the early 70s. They are 2.83 in diameter instead of .284. And a magnet will pick them right up.

I never shot them much in the past since back then they were not very accurate and they heated the barrel real fast. Although I did nail large Brown Bear at nearly 200 yards with a shot into his neck at the base of the skull. For this loading I coated them with graphite lock lube.

We have buffalo here in Alaska, but there is a minimum caliber requirement. 338 I think. Oddly enough it was just fine for me to harvest one with my .54 caliber muzzle loading plains rifles.


Well I better go back to bed, things are starting to hurt again.
Thanks for the feed back guys , it gets kinda lonely watching the clock on the wall.

Fine lookin' rifle Float Pilot !!! !

I think Vern's suggestion is a real good idea to try. Have seen that "sweeten" quite a few older rifles.

Hope you get to feeling better soon !


:cool:

Ooops. I see you already did some experimenting with the o.a.l.

I've never reloaded the 7x57 - how easy is it to experiment with case neck tension ?
What other bullets have you tried ?
