I ordered up everything Id need , Dif. in price of the Lapua & SSA brass was a mere 9cents per case so went with Lapua for now But still plan on trying the SSA stuff. Chamber was 247 so I got a 243 Bushing for the wilson does that sound right.
How thick are the case necks going to be?
I shoot for a .002, or .0015 interference fit for the bullet in the case neck. So, the ID of the case neck would be .002, or .0015 smaller than the 244 bullet OD after neck sizing.
With new brass, I allow for a .001 spring back after neck sizing.
