I see talk here of RL17 for the 6XC, and I have to wonder why not RL16? RL16 is temperature stable, RL17 is not, and RL16 gives almost a 100 fps boost over H4350 at almost exact same pressures, and with the same powder measurement. Seems to me that Alliant hit it out of the park with RL16. It’s wonderful in my 6.5 Creedmoor, highly accurate, no temperature issues, and should give similar results with the 6XC.

German, I have a bunch of unfired G1 brass; if you want some just let me know how many!

Just finished the RL17 report too & that looks very promising. As RCW3 brought up, there doesn’t appear to be any available in the US (I’d be ordering 5 lbs if there were!) so we’ll all be interested to see if later batches are equal to that which you’ve tested. Time will tell….

Steve, thanks for adding that data, I don’t have any Gen. 1 Tubb brass, so I appreciate knowing the numbers.

Watch for a very interesting article right here about Alliant’s new Reloder 17 in the 6XC and .308, I just finished it and it should be online shortly.

Thanks German for the updated info!

From those numbers it’s plain the G1 Tubb brass was marginal; 170.4 grains weight, 47.3 grains water capacity from my results back in 2005.
