[QUOTE="MagnumManiac, post: 2779847, member: 10755"] @MikeMatteson, I see your dilemma, but there are formula’s and reloading tools out there that can be used to help. QL or GRT can be very useful to determine a suitable powder and a max load. Once you find these parameters it’s a simple step to use a load 3gr below the recommended max and use that to find best seating depth. Yes, if you change bullets then you need to retest, my 338-416 Rigby Improved 45° was a huge gamble and after the first iteration was not what I envisioned, re-development took 18 months and cost quite a lot. I don’t regret the decision at all, as I wanted to get 3200fps from a 300gr pill and I did with some change. Anyway, back to the issue. As you realise that seating depth takes less components to get real world results, you will be very happy. Also, a 3 shot string is just fine for seating depth, as the results are normally quite different and the sweet spot will be easily seen. It normally tightens remarkably. I always go .005” increments to start from touching in my target rifles and .010” off with precision hunting rifles. My .222 Rem was very finicky until I did a seating depth test, it was amazing how much difference it made. That thing has all bullets touching at 100, wish my 22-250AI shot as well, but 1/4 MoA is still pretty good. Cheers. [/QUOTE]
