I need experienced opinions please. The plan:
Straight Winchester .284 using Bartlein Barrel 7mm 5R x 32" Finished, .277/.284 Bore/Groove x 1-9 Twist - Taper Barrel already ordered and on its way.
I will be using Lapua 6.5-284 brass necked up using the K&M 7mm expander mandrel.
Load development will be done using H4350 and Tula LRM primers.
Question:
Maybe this is asking too much but......I want to be able to use 180grain VLD's, Hybrid's or Sierra MK's.
From what I've read, some say .190 for VLD's and .210-.220 for Hybrids and not much info on Sierra's.
I'm thinking .210.....
What free bore will work the best overall?
Please, I need experienced Opinions......
