I've had many conversations recently about shooting a SAUM where limitations on muzzle energy becomes a bit of a concern, or certainly leading to uncharged territory. I will be shooting on a range next year that has a 4500 Joule limit, meaning that a 180 Berger cannot be driven more than roughly 2880 fps. Although I've shot around this mark, with good success, my fear is that even just a little temperature variation can cause me to be over. I am interested insome opinions from others to the best course of action for a situation like this.
So some data, currently shooting 32" barrel with 2209 and Sierra 183gn... This would make the limit even lower to about 2830. Given this, my options as I see it are:
1. Try to find a lower node.... does anyone have any ideas if one exists in the SAUM down low ? This would be like driving a Ferrari in second gear and on diesel....

2. Reduce barrel length to reduce velocity with the same/similar pressure pulse.
3. Change the projectile to something lighter (say 162 ELD / 168 Berger) to keep the velocity up, but would need to consider BC for longer ranges
4. Change to a 284 which shoot 183gn Sierra's very comfortably at the lower velocities.
Is there anything else to consider ?
Thank you in advance,
Albert
