Criterion No4 barrel

[ssj]

I run 46.5gr ADI 2209 with RP (Remington) brass and Lee collet dies - I am up to about 8 reloads in my No.4 with a standard chamber. The 2209 feels softer and is slightly lower pressure than 2208. Worth a try for case life problems.

or Ihave read

I am in that sort of order or a bit more 10+ with 2208 and I also use the Lee neck collect die. Several people have commented or I have read that the 2209 might have better accuracy so its something I am going to try in the future for sure. I just need to get the best out of the 2208 first then try the 2209.

"its the looser chamber tolerances of the No.4 mk2's" is this documented? can you point me at teh URL/reference? Everything I have read suggests the the mk2s were generally far better made than the mk1s, even showing a slight accuracy improvement. Certainly the 3 no4 mk2s I have are well very machined and finished.
