Any guidance as to a starting load with RL-16? I've got a couple of pounds of it in the powder closet.Per QL, RL26 shows to give quite a bit higher velocities over RL23. In fact RL26, with the heavier bullets, shows to be the top performing powder with regard to velocity. Another powder that I'd look at over RL23 is RL16. I'm using RL16 in my 20-250 with the 55gr Bergers and it's working very well.
Depending on your OAL and your particular gun, with a 75gr Berger, it shows 38gr as being close to max so a few grains less than 38 and work up from there.Any guidance as to a starting load with RL-16? I've got a couple of pounds of it in the powder closet.
Many thanks! With a little luck I should get time for a work-up this week.Depending on your OAL and your particular gun, with a 75gr Berger, it shows 38gr as being close to max so a few grains less than 38 and work up from there.
What velocities are you seeing with that combination ?22-250 Ackley with 41 +/- gr RL 23 and 80 gr amaxes. Shooting 7.5 twist Criterion barrel. Shooting 2”+/- (5) shot groups at 500 yards
I worked up to 43.4 grains of RL-26 in the .22-.250 AI, using fire formed Lapua brass, the Hornady 75 gr. ELD-M and CCI 250s. I stopped there, short of pressure signs of any sort, because the accuracy and velocity were more than satisfactory. Average velocity out of a 26" 1:8 twist barrel was 3,489 with very stable shot string statistics and 5 shot groups were running .5" - .7" consistently at 200.I was kinda hoping to get above the 3450fps mark with 75 Amax and the RL23. H4350 works at 34-3450 and does it quite accurately. I’m not yet sold on the RL26 stability in the smaller capacity cases just yet but the speed is undeniable.
I have a 30" barrel so 3550 is common with a few powders for me. Not looking to get super hot loads but accuracy is important shooting coyotes and ghogs at very long ranges. I'll be playing with the RL23&26 again soon.26” barrel. I’m pretty sure it was over 3400 FPS.
Yes exactly, Accuracy is high priority. The 41.0 +/- load of RL 23 using a 80 gr amax was going approximately 3450 FPS in my 26” 7.5 twist Criterion but that is where I found the best accuracy. It will shoot faster without noticeable pressure signs but I noticed deteriorating accuracy so I abandoned efforts of increasing the charge.I have a 30" barrel so 3550 is common with a few powders for me.

Well with the good numbers that the 75 ELD produces that extra 50 to 75 or even a hundred feet a second won't make much of a difference. The extra hundred feet a second I'm getting off that 30 inch Barrel is just free velocity.Yes exactly, Accuracy is high priority.
