22 dasher build.

[XP1K]

About to order a reamer for 22 dasher in the next day or two. Talking with Manson, they offer a reamer with .210" freebore, which seems a little on the long side to me. It's a custom order so I can technically order whatever I want with the same lead time. Currently 60-90 days.

Alpha offers two reamers, .115" freebore, and .169"

Bullets used for this build will likely be the 88gr eld-m, or the berger 85.5.

For those shooting or chambering 22 dashers, what's the preffered freebore ?

.210 would seem a little long for me, period.

I hope that guys with some actual experience chime in.

My only thought (that may be of help, or may not) is that your freebores are very similar to .223 cartridges. The .169 (ISSF) is pretty common among shooters who are shooting the 80-88gr bullets, while the guys who are shooting 90+ might look for a little more.

Looking at Manson's website now, their 22 GT reamer has .169 freebore "specifically throated for 90 A-Tips and 88 ELD-M". That might help you some.
