I found I hav shot for so long I was getting sloppy at shooting from field positions. More trigger time someplace besides the bench helps tremendously.
My largest problem was not properly (and consistently) securing the forearm. I was shooting much higher than I wanted to. It was just a lack...
I have started crimping heavy loads, such as 416 Remington Magnum and some others. I have have definitely seen an improvement in consistency since I did.
I ran a test in the 30-06 of new and 1x cases a crimped and not. I found that crimping was far more important for new cases than 1x for...
There are many that work well. I've used RL22/MRP and IMR 4451 to great effect with 140's. I haven't tried 7828SSC, although I have lots of it for my Weatherby calibers. I'm following any experiences with it with interest.
Even with the long freebore, I've found seating depth to make a big difference. One of my goto load uses 168 grain Barnes and 7828SSC. I wondered whether the depth would make any difference. It turns out .010" from my selected spot (after picking a charge with OCW) makes a huge difference.

I've done mine and it made the thing usable. It isn't just faster, it is more accurate.
If you write down the values before you change them you can put it back to factory.
I have a small metal insert in the end of the dispenser I got from Europe; that helped a bunch, too.
I always put book loads into Quickload so I can play with them as I prepare my OCW run. I'm working on a new load for 375 H&H using the 270 grain TTSX.
The maximum load listed in Barnes #4 calculates to 107,000 psi! I double checked all the settings, it just doesn't handle the bullet/cartridge...
I have a stupid hangup about clean brass, so as long as I clean it the same way each time, and use the same size sequence I will have the consistency I want.
I am going to figure out some way to measure the difference between the squeaky clean case and the fired case (both sized).
