A lot of places use the USPS Flat Rate Boxes and only charge the actual shipping charge. I know that Missouri Bullet does, so you can get a couple thousand bullets for about $12.00 shipping. That's cheaper than driving a couple of miles to and fro, looking for bullets that might not be there.

There's also no HazMat fee on bullets and brass, only powder and primers. I order a lot of my components on-line and let the Post Office do the driving. I currently load for 31 different calibers and it's much easier for me to order that way. Besides, I live in a small town on the coast and there just isn't anywhere nearby that I can buy what I need, so I either order or make it myself (bullets).

Hope this helps.

Thank You

Thanks for all the info.

I have more reloader questions, but I finally noticed there is an AMMO and RELOADING area, so I will post them there.

Any Updates?

Haven't seen any new posts on the forum in a month. Just wondering if everything is still on track.
 
Not trying to make any excuses but last I heard, B_M_1 had some personal things he was dealing with (done I think) and the shop where he was using the CNC equipment was busy as all get out doing production runs. I don't know how he faired with the recent storms although he didn't speak of any issues.

I had also communicated with him in the last 3 weeks. He said that there would be some delays, but he hoped to get back on track soon. I hope all is well with him now, for his benifit and ours.
 
Shadow1006, G_Conway, et all,
Thanks,
Out of town again til' at least the start of next week.
Shops machines still tied up.
Looking into some alternatives..................
Thanks,

Just found this thread and it sounds very exciting. I would be very interested in a .357sig for my 4006.
I have a Porsche, (go figure from my handle), and belong to a forum. A fellow wanted to make custom forged Fuchs in 17" for our cars. It was a long hard project. Took maybe two years but the wheels became reality and were/are stunning. I have a set and yes they were worth the wait.
Keep up the good work BM1 and looking forward to the next set for our 4006's.
 
Something I just propossed to BM1. What do you guys think?

Crazy idea for you, have you ever shot skeet with an over/under 12ga using sub-gauge tubes? Would it be possible to create a 357 Sig barrel that is threaded at the muzzle end so that you just drop it in the 10mm barrel and then screw on a cap on the muzzle end to secure it in place? Basically a sleeved barrel + the step down for the botttlenecked cartridge.

If the thicknesses allowed it this seems a simpler axnswer to producing a whole barrel.

Thoughts?
 
I would worry that the repeated firing would hammer the barrel and damage the rifling or throat of the parent 10mm barrel. :( Then due to the very thin structure of the sleeve barrel it may become warped or distorted. :( Pressures of 10mm @ 37,500 psi and 357Sig @ 40,000psi and even the 9x25Dillon which doen't have a SAAMI rating maybe hitting the 42,000 to 44,000 psi levels...

I think I will just stay with the full barrel specific for the cartridge to work with, insuring full ballistic performance! :) I work at the upper limits of performance with the 10mm, 40S&W, 357Sig and 9x25Dillon, so the pressures and velocities would be my concerns usin a sleeve type unit... Remeber shotguns are lower pressure and smooth bore as compared to the percision rifled barrels.

BM1, has his hands full with the current orders and getting time on the CNC machines has possed challenges...
 
The difference, as I see it, is you're comparing a low pressure round (shotgun) to a high pressure round (357 Sig), but using the same basic concept for both.

The fit of the barrel liner would have to be so tight as to make it hard to install and remove. The difference between a .400" diameter bore and a .356" diameter bore is only .044", which means the maximum the barrel liner walls could be is .022", which doesn't leave any room for clearance between the inside diameter of the 10mm barrel and the outside diameter of the 357 Sig barrel.

The other problem is the shoulder of the case. Despite what you read about the 357 Sig round headspacing on the case mouth, there is the second datum point on the shoulder to consider. If the shoulder of the case contacts the shoulder of the chamber insert too soon, the slide will be held out of battery. At the opposite end, if the shoulder of the chamber is too far forward, the case shoulder will blow out to match the chamber. This probably wouldn't result in a case rupture, but brass fired in that chamber would be excessively worked and would fail prematurely, in my opinion.

The idea is novel, but I just think it's not applicable in this case.

Hope this helps.

Yeah, I started to think the differences in bore diam. were way to thin after I wrote it. I think it would work if the bore size difference was greater. I don't have any idea how much different they would need to be.

Oh well, that's what I get for typing on my smart phone while eating my lunch. Too many ideas and not enough thought. Hehe.
 
Off Topic.

While we're waiting for production to start on the .40S&W/10mm conversion barrels, why not begin planning a .22TCM conversion for our 5906's, etc. :D

Happy holidays!

It's 2012... just playing.

Can't wait for the conversions. I just bought a 5-inch M&P40 Pro and a M&P40 Compact (first dedicated .40 pistols I've owned), but going to hold off on .357 SIG barrels until I get that for the 1006. Figured I'd try it out on one gun, and if I like the round, I'll pick up the M&P barrels afterwards.
