I saw a''carbine'' swedish Rolling Block -full stock, but much shorter than the usual long barreled military configuration.It was the original 12.7x44,not the upgraded 8x58r.Is anyone familiar with this model?-I think it is an ''artillery'' model,and there are several variations-some with the barrel extending a few inches beyond the stock-others with typical''mannlicher'' furniture.Don't know how they shoot or what velocity loss there would be with the shorter barrel, but they look pretty classy...
