Anyone have any info on real world results? Preferably the RL23, I think there is some info on the RL16 on Alliants site. 24" 10 twist, gonna try 175 & 210 Hunting VLDs, 190 Accubond LRs, maybe a couple others. Thanks

I would think that RL16 is going to be too fast to be ideal. I run it in creedmoor and 6xc size cases. I haven't played with RL23, but RL26 has been awesome in my 7 WSM and 6.5 SAUM, much better than H1000. I usually start with a grain or two below what they recommend for h1000 and go up from there. pretty similar burn rates and I get better velocity and ES/SD with the RL26

RL16 will work great anywhere H4350 shines. RL26 is a monster in the 300 WSM with heavies. I load the 200 ELD-X at 3015 fps without any trouble and it's surprisingly temp stable. My velocity shifted 7 fps across a 53° temp change from 70° down to 17°.

I'm using RL23 in my 7SAUM. It won't give you the pressure spikes over 70-80°F that RL26 is known for. It's not going to give as much velocity before pressure but it's respectable and likely in a nice node anyway.
