To Anyone:

I've been loading since I was 12 years old with my father and now I'm 40 and I've never loaded belted cases. I promised my father I would load him some rounds for his trip to Canada and my buddy some for our trip to Wyoming. Please help me set up the seater die so I don't crimp the neck or push the should back while seating. I got several loads done the other night but I messed up several bullets and cases before I was successful. I follwed the print in the Redding box but it didn't seem to work and I must have been doing something wrong.

I would also like personal load data for 140 grain Nosler Partitions and Accubonds. I would also like 150 Nosler Partition load data. Both rifles I'm loading for are Remington 700's.

I feel rather stupid with having this die trouble but I've never sized and loaded with belted cases. Please include your set-up for resizing these cases as well. Do you neck size and how or do you full length size for best results?

Thanks!!

I setup my seating dies for belted case the same way I do for non-belted cases.
First I trim all my brass to a uniform length. Then I take an empty case and put in the the shell holder and run the ram up to the top. Then I screw in my seating die until the crimp ring in the seating die touches the top of the case mouth. Then I back off the seating die at least a full turn. I never use the seating die to crimp. This avoids the bulged case shoulders caused by trying to apply too heavy of a crimp. When cases are properly resized, you really don't need to crimp unless you are loading a heavy recoiling cartridge like 416 or 458 mag . If I need to crimp, I use the Lee Factory Crimp dies in a extra step. The Lee dies are a collet style and squeezed the case mouth into the bullet rather than the roll crimp that the seating dies does.

For resizing, again, no difference for a belted cases vs a non-belted. I treat my belted cases as if they were non belted. As you probably already know, belted case headspaces in the rifle on the belt, not the shoulder like a non-belted case. The first time you fire a belted (or non-belted) case, it stretches to fit your chamber. I uses a case gage to measure the position of the shoulder on a fired (un resized) case then by trial and error, I start with my sizing dies backed off from the top of the ram as the die manufactures suggest. Then I full length resize a case and measure the shoulder position again. When I have the die adjusted properly (for my rifle's chamber), the shoulder is bumped back about .002". I repeat sizing and measuring until I get the desired shoulder bump. By doing this, you can increase your case life and you will not have to trim the case length as often since the case is not stetching as much each time you fire it. For calibers where I load for more than one rifle, I usually buy an extra FL sizing die for each rifle.

U F, welcome to the forums.

The situation as I see it is you will be loading for two different rifles? Additionally that you have had some sizing(?) or other seating (?) functioning (?) which is not clear on this end.

What you want to do is to full length size all the cases, but do not use too much lube to crush the shoulders(?) Then load which ever bullets you choose not to exceed the longest functional length in either magazine. You will also have to see how that length relates to the potential for contacting the rifling. I would not crimp any of these loads. My powder of choice for this cartridge is the R22, and by all means work up a load for each rifle and bullet weight range. My experience has shown me that velocity is not as important as accuracy, be your own judge on that. Have patience, they will do splendidly.
