Hello,
I recently got my Stiller TAC30 back from the gunsmith with my Lilja 6BR barrel rechambered for 6-6.5x47L. I've only had a chance to get it zeroed and do some basic load development. So far it's looking pretty promising w/ the B105VLD,only bullet I've tried thus far). I had a couple questions on the brass regarding some things I've seen thus far that had me concerned.
1) On both this rifle, and another one in 6.5x47L,different reamer, obviously, and different gunsmith) the factory brass miked something like 0.450" at the base of the shoulder, and fired brass is reading 0.458". Is it supposed to be expanding that much - or is the factory brass supposed to be that undersized? Also, when I size the brass to just bump the shoulder 0.001", get a nice bright ring just below the shoulder all the way around the body. Noticed the same thing on the 6.5x47L brass from my friends gun, also using Redding Type 'S' bushing F/L dies. Sized brass still measures 0.458" at the same point.
2) I noticed elsewhere on this forum someone involved in 600/1k BR mentioning that people had needed to open up the flash holes to get the 6-6.5x47L to perform to BR standards. Sounded a little weird, but the other night I ran a Russ Haydon PPC sized flash hole uniformer into my cases and the flash hole on all of them was undersized... as in it cut a noticeable amount of metal from the sides of the hole on every single one. Unless they sent me a wrong-sized tool, it seems like the flash holes are awfully small to begin with. Is this what was being talked about? Do I need to open them up more?
Thanks,
Monte
