Thread: Bushings

With the ring around it it looks like an earlier Redding.

Have you calculated your bushing required? Measure neck wall thickness (not always that accurate using a vernier) multiply by 2, add .264, take away 2 thou.
That will get you pretry close.

With my 6.5x47 using unturned Lapua I use a .287 bushing. So, your estimate of a couple of thou under .290 may be close. But, at the cost of bushings you need to measure and calculate to hopefully get the correct size first time.
