338 RPM ..the beginning

[FOTIS]

338 RPM …some self-extrapolated data I got to test



six lug Accumark 24" barrel



175 Hammer hunters so far so good.



69gr RL16 3050 fps (same velocity as factory in my accumark six lug, but they used 185 TTSX)

70gr RL16 3065 same hole as above

71gr RL16 3105 1/2" apart from above group



64 gr H4895 3220 fps safe max in my mind. just slight cratering.......



70 gr CFE223 3100 fps



Modified Ladder test to gauge where I am at with pressures. I had nothing to go on, and I did not want to waste a whole day pulling ammo.



Thinking 69-70 RL16 should be very accurate and is not close to max load.

Excellent work Fotis.
That 338 RPM is going to rock.

Looks like you’re on your way to another great stinging BEE

"Thinking 69-70 RL16 should be very accurate and is not close to max load."

Concur with that. I'd suspect you can stay at that level year-round and have a good shooting load at a very useful velocity.
