Thanks for the replies guys in my quest to gain knowledge on an infinite subject such as the Enfield lines was the fact I thought if it bore the stamping C-47 from BSA it was somehow there due to being more accurate than the norm which from what I hear and witnessed with the No.5's is abnormal as per wandering zero.

Or did they go there for an FTR, sorry about the pics I copied them from the site and these were the only 2 that did not come out microscopically, and just the cross screw in front of the mag well is this the infamous Ishy screw and to what end did this serve as is it just a peculiar Indian mod (at least they have the screw coming from the left?)
Bindi have you tried the 150gn .312 Hornady SP 3120 using AR 2208 - Fed 210 primer - 40 ~ 44 grains but like always start low with the loads and work up I left @1/16"of the cannular above the case neck and crimped into it max range 300M for this load (
NOTE: I claim no responsibility in the load data just what worked in my Savage 1942 No.4, from Quick Load program I have)
