Dac9976 Posted October 3, 2015 Report Share Posted October 3, 2015 Hi all I've acquired a 7x57r and I'm about to start some home loads for it. Can't really find much info on it, was wondering if the case length was the same as a standard 7x57 case? Cheers Danny. Link to comment Share on other sites More sharing options...
gbal Posted October 3, 2015 Report Share Posted October 3, 2015 The standard 7x57 Mauser cartridge case is 2.235" The European 7x57r is a rimmed version,essentially same dimensions,for double rifles (hence the rim for extraction. RWS are a good source of load data (RWS factory load is 123g @ 2955fps;139@2625;154@2690;177@ 2460.) Many sources gave data somewhat lighter loaded for the rimmed version in older doubles;so even more than usual,work up with care,though the same was true for the 7x57 in deference to older design rifles. You may have to consider regulation too,in a double-ie shooting to same POI-typically at 100y or m. gbal Link to comment Share on other sites More sharing options...
