Hope everyone is having a great Christmas, and that you have a joyful day with family/friends.
My wife gave me Sinclair mandrel expander die bodies for Christmas, both the "up to 338" body and the 35-50 cal body (since I have a 35 Whelen).
I'm looking to bounce some ideas off you fine folks to see if I've got a good or bad idea here. Currently, I prep using standard FL size dies, set to bump shoulders back between 0.002" and 0.005", depending on the round/rifle, targeting minimal shoulder movement for good functioning hunting ammo.
So, as we all know, the standard sizer is using an expander ball. After talking to some folks, it seems to make some sense that an expander ball may not be the best way to approach sizing the neck.
What I'm looking to do would be decapping with a universal decapping die, using my existing FL sizer dies with no decap rod/expander ball to bump the shoulders, and then use the Sinclair dies to set the necks to proper size. I know several folks use this process, but here's what I have in mind, and I'm not sure if it's a good or bad idea....
I happen to have a Dillon 450RL progressive press. This has no removable toolhead like the 550 and 650 series presses. So yeah, I have to reset my dies whenever I change things over. I was going to have Dillon upgrade the frame to a 550 for a removable toolhead so I could to easier caliber changes, but I'm thinking maybe it should stay a 450, where there won't be "wiggle room" in the die setup. Then I'm thinking I can put my decap in Station 1, Sizer (sans expander ball) in Station 2, and mandrel expander in Station 3. Station 4 can be empty. Then, instead of three trips through the old RockChucker for my brass, I could feed brass into Station 1, pull the handle, index the plate, repeat. Prepped brass would be kicked out of Station 4 when the plate is indexed, so all I'd be doing is feed a brass, pull the handle and repeating till the batch was done. Once the dies are set, of course.
Good/bad idea? Any "gotcha's" anyone can see in this plan?
I've also read some Dillon folks will D/T the pin slots for the toolheads on the 550's and bolt them in place to make things rock solid and give more consistent seat depths. I could potentially do the frame upgrade, tap those holes, and bolt in the heads, which means I'd be just sliding in the right tool head, bolt it fast, put on the proper shell plate, and go.
In my "I hate brass prep" mind, this seems like a great idea, so I'm thinking there's gotta be something I'm missing...?
The other part of this is annealing. I've looked at building annealing machines, which is an option. I've done it with the torch and drill, and I've gotten decent results, but I am constantly worried I'm gonna fry brass. An annealing machine could be cool, but I've also though of using a lead pot (I have a few of them) and a sand bath. Figure it's worth a try before going the annealing machine route, right?
