Thread: 338 ARC - An Early Guess At Reloading Data

Finally got round to feeding the 338 FARC some Power Pro 300MP, pretty much equivalent to Lil gun in terms of performance.

Started low as there is zero data for the 161gr OEP and this powder combo, accuracy is really really good just seeing how far this round can be pushed. Longer throat is starting to pay off with no pressure signs at 2340fps, I've still got another gn or so of capacity so 2400fps plus should be finally cracked next range session. I'll then retest against N110 and 2205.

20.6gn 1955fps
21.8gn 2027fps
22.6gn 2144fps
23.7gn 2171fps
24.6gn 2274fps
25.5gn 2342fps

these are the averages to date, will try and knock over the last of these loads this week coming
