Hello. I just joined the forum today. I have received a lot of good information here the last few months, so I thought I might pass some on as well. Recently I have been doing a great deal of work on a newly acquired 1907. I have found that Numrich has quite a few parts in stock on the website. The parts must come and go very regularly because I have noticed what might be out of stock one day is in stock only a few days later. This morning I noticed that they had buttstocks available. I have received a new forearm from them last week and it was really nice. I bought it as a spare because both of mine are good. Anyway, if someone needs some wood, you may consider this.
I am also making some brass from the 360 DW cases, but am unsure as how much, if any of an extractor groove is needed to be cut. The few that I have made seem to cycle (empty) by hand ok without any extra cut for the extractor. I have not fired any yet. If anyone would like to chime in some advice, it would be appreciated. The 351 Jameson cases that I have seem to be pretty large in the primer pocket (not getting but 1 reload), so I decided to try the Starline 360 DW for the cost savings. They have a good tight pocket.
I like to see load experience and recipes for plated and jacketed bullets. Right now I am just playing with some Alliant 2400 and IMR 4227 and 180's. Still trying to settle in on something that is reliable in the action, but easy on the rifle.
Thanks again!

I found that the extractor grove is more for being able to load the case .If you get a tight one going into the die the rim will pull out of the shell holder.

Thank you. That helps me because one of my rifles has a chamber that is a little loose compared to the other, so I have had some sizing that was on the tight side.

FYI I have found 4227 to be easier on the gun than 2400. I loaded some with 2400 (old powder in the metal can) & as I recall the max load was 19.5 grs. so I loaded 18.5 which was as hot or hotter than factory. I later learned that somewhere along the line they increased the burn rate of 2400 by about 10%.

I use 4227 in all of my WSLs- .32, .35, .351 and .401. For my .35 I use .38 SP brass with no extractor groove. I reduce the diameter of the rim with a file and a drill press, and cut to length. For my .351 I do the same with .357 Mag brass (no extractor groove).

Actually, the .357 Mag brass is perfect for the .351 (without an extractor groove). I tried .357 Max brass but found that the case mouths were getting dented and squished. I have a slightly new technique for loading the .351. I reduce the rim with a drill press and file to approx. .408" (more or less). Case rims from .404" to .411" work well in my rifle. I size the case in a 38/357 die. Then I run the case into a 9mm crimping die, for the length of the bullet that will be seated. The bullets are .352" and the 9mm crimping die puts good neck tension on the case. Expand the case mouth slightly to accept the bullet. 17 grs IMR 4227. The bullet slightly compresses the powder, which is fine. Seat with a 38/357 seating die with a slight crimp. Works well.
For what it's worth, I chronographed some of these rounds recently: With 17 grs IMR 4227: 1400 - 1600 fps. I fired off one vintage factory round: 1879 fps.
