Alliant Reloder 16 powder

[Stumpkiller]

That's the trouble with being on the "leading edge" with a newly introduced powder: no load data.

I am very happy with their RL-19 in my .260 Rem. I have a compressed load that is showing no signs of overpressure and, though I have no chronograph, shoots well. Based on what the manuals tell me it's good for better speed over my prior powders, H4831 & H4350, though the burn rate falls right between them. But that's a very different powder than the new RL-16, I believe.

If it were me I'd look at the H or IMR 4350 loads and drop them 5% for a conservative start. Alliant says that "The Reloder 16 burn rate is slightly faster than that of Reloder 17, well within the 4350 burn speed band. But burn rate and volume are not directly proportional. However, looking at the Nosler load data for a .257 Roberts (115 gr bullet & H4350) vs. the Alliant RL-16 load data for the same cartridge and bullet shows they are within 1.0 grain for similar MV. Your case is smaller, but the ratio should hold.

Good luck and be careful.

You can use H4350 data for a start point. R16 works very well with heavier bullets. Im not sure of the exact charge weight my brother is using but he is getting well over 3000 fps with 100gr Sierra match kings.

I hope this may help try AmmoGuide.com it's a payer site you can register as a guest, 250 Savage is in their list of Cal.they list 287 loads for the 250 Savage you will have to search to see if they list the power you want and the bullet weight you are using.
Good luck and careful if you decide to register tell them i sent you there (balljoint)

Thanks for the info and suggestions. Have to look into the suggestions. I think I'll give Alliant a call and see what they have to say. Might just tell me to keep my powder dry!

Called Alliant today and talked with one of their ballistic reps. He advised Re16 a great powder for for the right cartridge, as all powder has that trait, but, the 250 Savage isn't one which Re 16 is good for 'in the short. The rep advised that the 250 doesn't have enough case capacity to make the round a good performer with the Re16. He said the 243 Win has for example, but not my 250 Savage. Alliant like a lot of powder/bullet companies either delete rounds like the 250 Savage or have little information on them due to as he advised, not as popular as once was. He advised even if they had the 250 on their site or listings, they wouldn't include any loadings using RE16. Advised if I want the no temperature sensitivity and copper cleaning features as found in Re16, their AR Comp has both and is in the burn rate and case/performance area of Re15. Advised him I had good results from Re15, Varget, and IMR3031. Have to shelf the idea as I don't want to wildcat it and his reasonings sound good to me.

Sensible response.

When IMR Enduron 4451 first came out (and H4350 was nowhere to be had) I tried a load by dropping back one grain from my H4350 load - which was kind of the information on the Hodgdon Reloading Data website. I loosened the primer cavity in the first two rounds - noticed in the second when the primer fell out and jammed the action! Like you the same qualities attracted me: copper cleaning and temperature stability.

I went back to shade and Barnes CR-10 Copper Solvent.

I have a pound of RL-16 here that I've been meaning to play with in my .250 Ackley Imp. but haven't gotten around to it yet - mainly because the brain for my chrono took a crap and I haven't ponied up the $$ to replace it yet.

Alliant telling you that it's a case capacity issue doesn't make much sense to me as the capacity difference between a .250 Savage and a .243 Win. isn't that much.My guess is that they just haven't done any testing with it in a .250 Savage so they're erring on the side of caution by not recommending you use it in that case. I've seen several posts on other sites where guys have been playing with it in the .250 Sav. and having good results.

As with anything though, you have to stick within your comfort zone. Some are more adventurous than others when it comes to experimenting with different powders in different cartridges.
