Hello everyone,
I need new dies for my custom 300 PRC on Defiance anti action. Let's leave the cost aspect out of this conversation and focus on technical and performance factors to achieve the best results at 1000 yds.
I will be using a coax press and I am searching for the best dies and I also need help understanding how some dies work.
If I understand correctly there are two major ways to size your brass, bump the shoulder or FL resizing. I read enough to understand that its an ongoing battle regarding which method yields the best results. In both cases, neck tension makes a difference.
My questions are:
1. With a co ax press can you use a FL die but chose how far down I want the neck bumped?
2. How far down does a FL die goes? I had a 300 win mag and always had issues because the dies won't touch far enough.
3. Would custom dies fix all the above?
My understanding with custom dies is that they are manufactured based on 3 fired cases. That doesn't make sense to me (I'm sure I'm missing something); my assumption is that the OD is measured in multiple spots and the smallest OD-x thou is picked for the ID of the die. That is somehow ok, but how do you know the length? Most cases don't stretch all the way from one firing. Would be better to use an imprint of the chamber, or just send the barrel? I'm trying to understand what advantage custom dies bring to the table and the only one that I see is the custom ID.
I know that Forster and Redding make good dies, I don't doubt that; personally I had really bad results and terrible customer support experience with Redding, good results with Forster and unbelievable results with RCBS.
