One more tidbit of information on RL33. Yesterday, my brother and I tested our drop charts and fine tuned things to the point we are ready to roll. It was 60 degrees yesterday.
Last night, I left my rifle and ammunition for my 300 Allen Xpress in the truck. It got down to 25 degrees last night.
After first light, I ran back up to test the results of a first shot, cold barrel would be. On the way up, I put my ammunition box in the back of the truck and I put the cold rifle in a hard case that had also been sitting out all night so they were all roughly 25 degrees by the time I got to the range. Set up, found a very small target rock. Measured it at 893 yards. Looked up the hold over on my drop chart that I had just attached to the scope the day before. There was more wind today and I set up intentionally having to deal with a near full value wind to test my windage dopes as well. Took the recommended hold over and estimated the windage dope and let the first and only shot go. Landed perfect height wise and on the right edge of a rock that was 7" tall x 10" long. So from a cold barrel at nearly 900 yards, RL33 was dead on the money. The day before, in the 60 degree temps, the 300 AX was dead on at 380, 590, 890 and 1030. Today with ammo and rifle +30 degrees colder, there was no measurable change in point of impact.
Next up was my Raptor LRSS single shot chambered in my new 338 Raptor driving the 300 gr Berger to 3150 fps. I only bring this up because I am using another RL powder in this one, RL50. Same test set up, ammo, rifle cold. Set up at a measured 1098 yards. Again, height was as perfect as it could be, wind got me a bit more then I expected but shot impacted 6" to the right of point of aim. PLENTY close enough to point of aim to be a great killing shot on any big game animal.
Both RL33 and RL50 seem to do pretty well with temp changes what one would see normally in a single location hunting situation. Now if you went from the top of a mountain in the rockies at 10 degrees and 9000 ft elevation and then went to hunt just off the coast of the gulf for Texas Whitetails where its 80 degrees and 100 feet above sea level, you may see more variation that may require some adjustment but for realisitic one area situations, I have not seen any real issues yet.
Confidence building for sure.
