Alliant Reloader 17 Rifle Powder 5 lbs
Alliant Powder, a division of Alliant Tech Systems Inc., (ATK), will be shipping new Reloder 17 powder in mid-March, 2008. This is an all-new, double-base powder produced in Switzerland by NitroChemie for Alliant.
It is a high-energy powder with a burn rate close to IMR 4350, and “midway between Reloder 15 and Reloder 19.
” The powder density is optimized for the short magnum cases such as the 7mm WSM and 300 WSM, but it also will work very well with cartridges such as .243 Win, .270 Win, 6XC, and 6mm Remington, according to Alliant Product Manager Dick Quesenberry.
Reloder 17, a state-of-the-art propellant, promises to deliver higher velocities than competitive powders for many popular calibers. If you have the “need for speed”, Reloder 17 is worth trying if you’re shooting IMR4350, H4350, N550 or similar powders right now.
The new RL17 will be offered in 1-lb. and 5-lb. containers and will cost about the same as other Alliant Reloder powders, such as RL15 and RL19.
Mr. Quesenberry noted that Alliant tested many formulations, from a variety of makers, before choosing the Swiss-made Reloder 17. Alliant’s new RL17 is NOT the same as Norma URP, produced by Bofors in Europe.
According to Alliant, the new Reloder 17 tested superior to URP (and most other powders in that burn range) in all major criteria: Velocity, Accuracy, ES/SD, material consistency, and resistance to ambient temperature-induced pressure changes.
Reloder 17 features an advanced, penetrant-type kernel coating. Alliant believes this is superior to typical surface powder coatings because it provides a more consistent, progressive burn.
The powder pressures do not spike as sharply as with surface-coated powders, but remain more consistent throughout the burning process.
Testing has shown that Reloder 17 offers big velocity gains in many cartridges compared to other powders in the same burn range. For example, in the 6mm Remington, using an 85gr BTSP, Reloder 17 delivered a 156 fps gain over all other powders listed in the current Speer Reloading manual.
Likewise, in the 300 WSM with a 180gr BTSP, Reloder 17 offered 104 fps edge in velocity over all powders listed in the Speer Manual. Below is a chart showing projected velocity gains compared to other Speer Manual-listed powders.
Alliant has already done extensive load testing in its ballistics laboratories and has load data available for 20 popular cartridges, including .243 Win, 6mm Rem, 6.5×55, .260 Rem, .270 Win, .308 Win, 30-06, 7mm WSM, 300 WSM, and 300 Win Magnum.
That is a very excellent write up on RL 17 in todays Daily Bulletin.
I cannot wait to try the powder out in a variety of cartridges. If RL 17 is anything like RL 15 is to powders in its respective burn rate, the results for RL 17 should be good.
I can see immediate uses for this powder in cartridges like the 6XC, 6×47 Lapua (i.e. necked down 6.5×47 Lapua), 284 Win, maybe the 6.5×284 in lieu of the regular favorite H4350.
While I love some of the Hodgdon powders, most of their stick powders tend to leave that glazed carbon build up just forward of the throat in barrrels (that’s a pain to get out),
and I have never had that issue with RL 15 and presumably RL 17 will not either.
Has the data on the propritary .243 – .260 – 7mm-08 –
.308- ect. with medium weight bullets been done yet?
i.e. 90gr. – 120gr – 140gr – 150gr respectivly,
I have appreciated your great powders from Alaska to Montana. Thank you, Roberoo
