Thought some would be interested to know Alliant now has some initial load data on their website. The 270win data looks good if it's true.

As they come out with new powders, it bothers me, that you can't get Alliant Products anywhere... hit and miss at best...

have been a fan of their stuff for a long time.. however availability or lack of it has kinda soured that big time...

I hear you Seafire...there are some Alliant powders I see most everywhere...the new ones not so much. Hodgdon isn't a lot different, some of theirs are hard to find. Western is probably the worst in my area.

Looking at the RL16 data, if their loads "hold water", it makes the 7-08 a 270, and the 270win loads are basically the same as some of the 270WSM loads. Interesting.

A published 270 Win load with 130g bullets above 3200fps.
Now that is a potent load. Sounds far from a compressed charge too.

Wonder how fast it would send a 110g X-Bullet?

oh I love Alliant Powders...

just like I'd like to spend a few nights with a young Anne Margaret, but the availability of either sucks....
I admit to having stocked up nicely for the time being with AR Comp, which is like a Temp INsensitive RL 15.. which I am sure RL 16 is also...

but probably from different sources and I am sure RL 16 is closer to RL 15 burn rate, than AR Comp which is a little faster...

but working up my own loads when reload data was non existent, it gives some decent velocity/accuracy out of the 223, 22.250, 243, 260 and 7/08, 6.5 x 55, 6.5 x 57 and 7 x 57...

Can anyone tell me what the right most column of their data is called "notes"? It'll say: 0.220" C or some will have "air" in the place of the "C".

Wow those loads have some zip. I hope they live up.

Inches of compression vs. inches of air between powder and bullet maybe?

Somethings a new everyday....

First I've herd of RL-16

Thanks for the tip. Now, I need to check it out.

yeah, if I pick up some, the 243, 260 and 22.250 are going to be the trial candidates to road test it...especially heavier bullets in the 22.250 in my fast twist barreled one..

I like Alliant until I actually load them. For whatever reason my rifles don't come close to matching their published numbers, even accounting for barrel length. On the other hand my rifles match Hodgdon almost perfectly. But I'm sure I'll be swayed by the potential and try it out.

Exactly. They can't keep up with what they have now and they keep coming out with more!

Link? I'm not seeing it.

Here's the link to their data: LINK.

Paul, a guy from Alliant, provided an ETA for this here: Alliant on THR

The 270 Win/130 gr. numbers look impressive but then the same combo in 270 WSM doesn't budge from previous powders. Must not be the ideal speed for the WSM case.

I'm getting a bit tired of waiting... I've yet to see it. Heck I haven't seen 23 or 26 in a store, but at least I've seen them online.

Agreed. My LGS received a shipment of Alliant Powder today. It contained RL 19 & 22 (yawn), no other rifle powders.

I did an extensive search on-line today. The only site I found that even listed RL 16 (out of stock) was grafs.com.

I'd sure like to get my hands on some RL 16.

A 30-06 150 gr. TSX at over 3000 fps should take care of most chores needing done

I'm on my way to Whittaker's to pick up a one pounder. I'll let you know how it works in a 7mm-08 Montana in a few days.


PS. I must have had a brain fart. Could've sworn I saw some on the shelf yesterday. The GM told me they have not had RL 16 yet. My bad.

It is just now starting to ship, per Alliant.

Anyone seen any yet?

Not a trace.

I talked with an Alliant Powder Tech last Friday and was told that RL-16 had not been shipped yet and they did not know when it would be. Alliant has to wait on permits, etc. to start shipping per the rep.

Great news, thanks.

I've got to admit I've had 16 in my shop for 3 months now but haven't had time to play. Anyone have time to test, play with it?

Only in a .260 with 130 gr Accubonds...42 grs got me to 2,800 fps vs. needing 44 grs of H4350 to get me to the same velocity. Accuracy was good.

Worked some with R 16.
It is more bulky than other powders of the 4350-ish burning rate.

.220 Swift: it seems a bit faster burning than R17 and very similar to 4451.
.30-06: it seems faster than H4350. Some loads were slower & some faster than 4451.
.358 Norma: it seems faster than H4350 and about equal to 4451.
In the .370 SAKO it gives about 100fps less velocity with the same charge of R17.

Usable in the Swift but, as yet, undecided if it is as good as my favorite R17. Research continues.
My new favorite for the ’06 – the Alliant load with 180NP and appropriate loads with 168 TTSX and 200NP (see: JBs The Rules).
Usable in the .358 – nearly as good as my favorite H4350 and at least equal to 4451.
OK in the .370 if you can settle for 286 gn bullets at 2400 with compressed loads.

I've been using quite a bit of RL16 in my 6.5 CM. All of these loads have been safe in my rifle. All three are also 1/2" loads. The Gameking loads are seated .020" off the lands and the TTSX load is .100" off the lands and compressed.
