1. SS press : $40-120?
2. Set of 25-06 dies for your rifle: $20-35?
3. Shellholder for that caliber (Lee dies come with the shellholder)
4. Scale that is accurate to about 0.1 grains is nice. And accurate at very small weights. (A grain is 1/7000th of a pound, and there are 15.4 grains in a gram). For rifle you could probably get away with 0.1 gram resolution IF you verify the accuracy and only use the scale to calibrate a dipper or a powder measure. And if you're ok with doing the conversions! Since you probably don't have any accurate weights in the 10-30 grain range, you could use, say, nickels to verify accuracy in the 75+ grain area of your scale, and then weigh only the sum of multiple charges to get into the verified range of your scale. A nickel weighs 5.0 grams. But that's even more inconvenient, lol. If you want to weigh every charge, you will need a good loading scale.
5. Calipers are almost necessary and they only cost $10.00. You might get by without them, if you use, say, a Lee trimmer that is already setup to the right length. And if you don't run into any problems with your reloads. But if you run into an issue, you will be in the dark, somewhat.
6. Some way to prime your cases. Most presses can also prime, but some of the cheaper ones can't. So it's a false economy, since you have to buy more stuff to prime the cases, such as a hand priming tool or a ram-priming setup.
7. For bottle neck rifle cases, such as 25-06, you need a way to trim the cases. I suggest a Lee trimmer and 25-06 guide/holder for your motives. Another $12.00 to $15.00 or so, for those two items. And you will want a cordless drill if you go with the Lee, so that's assuming you have one.
8. Some case lube for sizing your cases. But I've heard that ivory soap works.
9. Some way to get the powder into the little 25 caliber necks. If you buy a powder measure, you don't need a funnel. If you want to use a dipper, you are going to need one.
10. Powder measure. If you're handy, you can make dippers by cutting down spent cases. But you can buy a powder measure for $35 and up.
11. Definitely add a chamfer tool to your cart.
If you add it all up, a Lee Breechlock kit might be cheaper. I dunno.
