ReloadSwiss Powders

Are any available here in the U. S.?

Short answer is no. But, there is a chit house rumor that RE-17 is RS60.

Could well be as I have heard that some Alliant powders are ReloadSwiss powders. QuickLoad lists a half grain difference between the 2 [Reloder17 and RS-60] for a Barnes 127 gr LRX bullet in a 6.5-06AI.

There are four Nitrochemie (Reload Swiss) grades available in the US all under the Alliant brand name, all 'high energy' (infused nitroglycerin into originally single-based nitrocellulose kernels) types and also all using Nitrochemie's patented unique 'EI' infused deterrents technology.

Re17 ................. OEM: EI-Niesen 145 ................... RS60

Re26 ................. Unknown ................................... No RS Canister equivalent in the UK.

Re33 ................ OEM: EI-Niesen 170 EA ................ RS80

Re50 ................ OEM: EI-Kolumbus 12.7mm .......... No RS equivalent I know of, but it was available in the UK under the name 'Elcho 50' for a couple of years.

That leaves six rifle grades available in Europe under the Reload Swiss brand name that don't have US equivalents, three single-based (RS30, 50, and 62) and three high-energy / EI (RS40, 52, 70).

RS30 is equivalent to Alliant 2400 and similar fast rifle powders; RS50 is very close to Viht N140, so much so that their loads data are usually interchangeable; RS62 is in the same bracket as IMR-4451 and 4350, H4350, Alliant Re16. A superb non-temperamental powder that provides good MVs.

RS40 is said to be the canister version of the bulk grade used in Swiss GP90 62gn 5.56 ammunition - high performer in 223 and in 308 with 155s. (Spectacularly so in the latter, but not consistent and a real barrel burner at top loads so after a brief spell of being 'in', few use it for this cartridge today. RS52 is very similar to H. VarGet and has the same applications - 6BR, 308 Win with a wide range of bullet weights etc. RS70 is a magnum powder equivalent to Re22 / Norma MRP.

Thanks for that info. I was interested in the RS-76 as it is supposed to offer about a 275 fps velocity increase over my current 6.5-06AI load of 59.3 grains of IMR7977 and the Barnes 127 grain LRX. The load shoots pretty good and I like the reduced copper fouling from the IMR7977. Both SR-76 and IMR7977 have the same temperature insensitivity and a copper fouling reduction additive.
