Nitrochemie ? Quick Load

[Rtheurer]

Reloader 26 wouldnt happen to be in Quickload already under one of the None imported powder's listed in the program would it?

Did a quick Search and didn't find anything...

RS60 = Re17

RS62 has a similar burning speed to RS60 / Re17 / H4350 and is an excellent alternative to the 4350s in 260 Rem, 6.5mm Creedmoor and suchlike. It has no infused nitroglycerin in its formulation unlike the Nitrochemie powders used by Alliant ATK and has a much longer tubular grain structure.

RS70 is a 'High energy' propellant (infused nitroglycerin) as per the Alliant range and has Nitrochemie's patented 'EI' deterrents infusion technology, but appears to be considerably faster burning than Re26. Nitrochemie shows it as equivalent to Re22, Viht N165, and Norma MRP in this respect.

Alliant lists a max Re26 charge of 60.2gn for 270 Win with the 150gn Sierra SPT whilst Nitrochemie lists a starting load of 49.5gn and max of 56.0gn for this combination. Running that through QuickLOAD gives a PMax of 4016 bar / 58,248 psi and an almost identical MV to that quoted by Nitrochemie (2,956 fps) assuming a 24-inch barrel is involved. (Neither Alliant nor Nitrochemie show a barrel length) Nitrochemie lists loads for 110-150gn bullets for RS70 in the 270; Alliant only three makes of 150 with Re26 suggesting it doesn't see this powder as suitable for lighter / normal weight bullets. (But that may be reading too much into this given Alliant's sparce data combinations for all of its powders.)

Using Alliant's max Re26 load (60.2gn) in QuickLOAD produces a calculated PMax of 74,791 psi in this combination.

RS80 = Re33

There is nothing listed between RS70 and RS80 in Nitrochemie's European product data suggesting Alliant Re26 is specially supplied.
