Thanks Trebark! I will give that a try today.

Check out RL-22. I got 2,900 fps out of a 20" tube with 129 gr SSTs

I still want to try H4350 with my SSTs, just not sure I'm going to get the velocity/accuracy that I get with RL-22, and I keep reading conflicting experiences about the temperature sensitivity of the RL powders.

Take it from someone that has shot quite a few different RL powders in various conditions. RL powders are very temp sensitive.

You're welcome. My load is a 130grain JLK with 45.0grains of H4350 lit by CCIBR2. Produces 3000fps in a 28" barrel.

Re: 260 Rem Load Recipeies?

Thanks again Trebark! I am currently moving from the 308 to the 260 for tactical matches and have a few coming up. I am trying to get a load developed to shoot, as mentioned earlier, H 4831 sc was great, but only produced mid 2400 accurately with the forementioned bullets. Loading them hotter did not hold the accuracy I wanted, good, but not good enough, as I know what this rifle is capable of doing.

I did use your load info, but will be modify slightly, trying my 142 SMK's, 140 A max's and 139 Lapua's with the H4350. In addition, I will be trying the BR-2 primers over the 210 Match I currently use.

I hope to get out this week sometime and try the loads, I'll post the results after.

Again, thank you sir!

The 140grain bullets are really nice and have great BCs making them even more attractive. Take a serious look at the 130grain options though. Most tactical matches are 600yards or closer and only a few 1000+. With that being the case, the superior velocity of the 130class bullets exceed the BC advantage of of the 140s. Heck, I was in Wyoming this past October and was easily killing rocks at 1500+ with the 130JLK. (G1 BC = .593)

Well, it's a hunting load for my rifle and temperatures for PA deer season don't really vary that much. I might not get 2,900 fps when them temps are below 20, but I don't think I'll see that much of a difference in velocity going from mid 50s to the 30s. I'll check the POI/scope zero before the season starts and the temps are a bit cooler, but for a hunting rifle, RL-22 should be just fine. Shooting a max load shouldn't be an issue in the summer as long as I don't let the ammo sit out and bake in the sun or on the dashboard.

I ran into the same thing with 129 gr SSTs with H4831sc...velocity was too low on the tightest groups. I just loaded a few rounds with the RL-22 only varying from Federal 210GM and CCI BR-2 primers. I'm interested to see how the results compare.
