[QUOTE="Tac-O, post: 2590592, member: 109994"] I picked up my rifle a couple of weeks ago . Everything looks great! Chamber and throat are cut very cleanly. Everything was done the EXACT way we had discussed and agreed on :) I don't have a picture of the rifle but will post one sometime soon. It's not much to look at having the factory stock, but it does have a great very durable bead blasted finish that matches the action really well. Here's what I did. Manson chamber and resize reamer, 30-284 improved (40* shoulder and 0.486 shoulder width). 0.310 neck length and 0.130 freebore set up to have juggs seated 0.020 off and bearing surface 0.050 ahead of the shoulder/neck junction. I should be able to seat 200gr bullets ahead of that junction with 0.020 jump. No turn neck at 0.342 for Lapua and Peterson brass. I had the base and shoulder dimensions on the resizer reamer reduced by 0.001 from standard to help prevent clickers in the event I want to use hot loads. The base to neck/shoulder junction dimension was reduced by 0.004 to setup easy fire forming per Ackley's method. I used a 30cal resizer die blank and Lee seater die to have the smith cut my dies from. I broke in the barrel with a few rounds a couple weeks ago with some junker bullets I had and the remainder of a pound of staball. Shoulders look sharp and I think the cases are fully formed based on measurements. Accuracy was promising! I'll be going to the range today to start working on a load. I'll first find pressure and then load at the bench. This will be a first for me. I estimated where max pressure would be with the Gordon reloading tool. 185 juggernauts ~0.020 off lands Cci200 H4350 55-57.5gr to find pressure Peterson brass 1x fired Left is straight 30-284 brass, right is fire formed 30-284 imp brass [ATTACH type="full"]384392[/ATTACH] [/QUOTE]
