New build underway 338 RUM single shot

[officejet]

Thanks to a lot of advice from Jim Briggs and Scott Null, the new 2000 yard gong ringer rifle project has begun.

Right Bolt, left port match action
New bolthead and firing pin assembly
FT/R stock
34" 3 groove treated barrel, 1"@ muzzle
20 minute rail
Schmidt & Bender 4-16x50 to start but will be moving to IOR as they make the new 12-52x56 scope with a 35 min rail.

Yeah I know you can't open the bolt and extract a loaded 3.6" round w/o hitting the bolt release first, but I can't recall ever unloading a loaded round while playing at gong ringing.

Should be a worthy grandchild to my current going on 50 years "gong gun". M70 Bull Gun 300 H&H, BalVar 6-24, Canjar SST, that went to Perry twice.

Figure the 338 RUM will about double the "beaten zone" of the 300 H&H rig.

Changing from 20 to 35 minute rail as the new IOR 12-52 is going on it.

A 50 MOA rail will work better. If memory serves me, I use a 65 MOA rail to zero at 1K yards with the 338 RUM that I built my shooting buddy.

Have you socked in a supply of 300 gr SMK's yet?

We have coated ALL of his bullets with WS2/Danzac. Now that HBN is available, I would use that instead. To date, there is just shy of 1500 rounds down the Rock Creek barrel. I would HIGHLY recommend coating the bullets.

Retumbo will be your new friend. Trust me on this. :)
