Last fall, after finally finding a 'smith who would do a barrel for the 700ML build (Brux barrel), I got it to him Nov 30. Then bad things started happening with his health, and is still plaguing him, but he finally got the machine work done. How do you think he did?.............................     I'm hoping and praying the doctors get to the root of his problems soon. After he contacted me, and I didn't know him from Adam, I looked all around the 'net for reports. Any who had him do work were very satisfied with no bad reports at all. From the photos, it appears I will be very happy as well. Should be getting it next week so I can begin doing my end of making it a rifle. Yippeeee!! ;D |

I ain't no machinist but it looks great to me! Did he do the plug install also?

He sure did! That's the part most 'smiths were wary of doing, but he said
he couldn't see a problem with it.

Looks good to me. You can have a BP with extra threads too.  |

When the breechplug threading comes all the way out you just can't use an old style Savage plug unless the tool is modified. Not a problem with the hex head. And yes, you could build a custom plug with more threads. The work looks well done, good luck!

Danno
The machining looks real good and that is a nice crown. It looks like 11-degress with a nice uniform chamfer. For sabot loads you are going to enjoy having that crown and chamfer.
Look forward to hearing your comments on range results.

That action looks real familiar. |

ET, yes the crown is 11* with a 45* countersink. Thought that would be
good for both saboted and sabotless. The Brux barrels are 6 lands &
grooves, so indexing sabots may prove to be frustrating. Was doing this
mainly to go sabotless.
Never planned to go the old style plug route. The extra threads were left
to possibly slow down the breech plug in case of a catastrophic event. But
if the plug threads were stripped rather than the barrel threads........
Fish & Luke, there could possibly be a couple more threads on a custom
plug, but the socket needs something to grab.
Luke, how could ya tell this action from all the other stainless actions
you have handled......don't they all look alike? ;D

Looks like he did the head spacing on the plug also? Nice work. You actually do have some extra threads since the Savage doesn't use them all.

Looks like he did the head spacing on the plug also? Nice work. I had done some work on the BP to decrease the angle to fit more into Hunter's bolt nose, and he did his magic for the proper depth of the BP otherwise. I don't know how the heck he got the proper measurements, but he would say, "It's what I do." |

Most interesting. When are you going to shoot this thing?

Your work looks nice.
I have a few questions.
1. What is the barrel contour you are using?
2. Why did you chamfer a good 79* crown?
3. Are you planning to use a 209 primer or a Shell case headspaced off the nipple?
4. Are you planning on shooting loads over 2,600 fps?
Please don't take my questions as complaints or critisim, they are purely for my own information. I am still learning at this game.

Nat, Not to sound critical but you still have a lot to learn about SMLing and what we have came up with around here over the years.
1. As far as barrel contour I do not know exactly what he used but the most common is a #7. Fishhawk has even came up with some custom contours to fit the Remington factory stock and still be beefy in the critical areas. Another is the Remington Sendaro Varmint contour.
2. The chamfer is not only to ease in bullet/projectile insertion, but you also do not bang up the crown as much with the ramrod. I learned old school and it is a 79° muzzle face with a 45° crown. You may be used to a straight 79° that benchrest CFs use. You do that on a ML and you'll be shaving your ramrod/bore guide.
3. This is a 700ML with a Hunter bolt nose to hold a 209 primer going into a factory Savage breechplug. The breechplug has been slightly modified to match the angle of the Hunter bolt nose and for the final headspacing. The Savage breechplug is "off the shelf" and comes with a replaceable vent for $30 and around here has been used for many SML conversion platforms.
4. He says he is planning to shoot saboted so he will probly be shooting 195gr Barnes or 200gr SSTs which guys have pushed as fast as 2900fps but the sweet spot seems to be in the 2700s for those bullets.

DBinNY, it probably won't be 'til next month. Still got work to do on my part,
and I'm not nearly as fast as Hillbill or Richard. I'm going to pillar bed it and
do more work on the BP, along with modifying a spare (don't ask, the
answer would give some here an excretia hemorrhage).
Rusty, to answer your questions:
1. The barrel is a Palma contour. Ken at Brux Barrels had one on hand
which was kept at 1.25" out to close to five inches which gives plenty
of steel in the "chamber" area.
2. See Rossman's answer, he is much better at explanations than I. ;D
3. 209 primer with a modified Savage breech plug.
4. It will only get light loads in the beginning to see how things go with it.
After that, only lighter bullets will get shot over 2600fps, i.e., saboted
.40's, 200 FTX, 225 FTX. The 250gr bullets, probably right around that
2600fps. Anything heavier will be slower........don't care to compete
with Bad Bull or Swinglock. ;D ;D

Was doing this mainly to go sabotless. Dannoboone Don’t write off indexing the sabot to the bore even with 6-lands and grooves. Hope I can explain this properly so it’s understood. If the sabot is orientated exactly the same way on every shot using the same pressure points for support hopefully the release when coming out of the bore will be exactly duplicated from shot to shot. By altering the location of the pressure points on the sabot load may have a possible affect on the final release from the bore. You’re in a good position to prove or disprove this possibility. Ed |
