My favorite load in my Tikka 6.5x55 is 50g of H4831SC pushing a 140 Nosler Accubond. Not the fastest load clocking around 2700, but is very accurate.
I've also had pretty good luck with 120 Ballistic Tips and 50g of H4350. Those get just under 3,000 Fps, and also shot pretty good. My last two 5 shot groups with this load hovered between 1/2 & 3/4's of an inch.
I had my M70 Swede out this morning to try a couple of powders in new Hornady cases. I was shooting some 129 Interbond seconds I picked up a few years ago. I have heard reports that the bullet can be difficult to shoot well, but my rifle seems to like them combined with H4831. 3-shot groups, a pair of each at 48.0, and 50.0 showed good results. For some reason I couldn't figure out, both groups at 49.0 were larger. (50.0 grains is 1.5 grains above what Hodgdon calls for when shooting the 129 SP.)
I also gave H414 a go, but groups were widely spaced horizontally. 43.5 is Hodgdon's max for the Hornady 129 SP. Both 43.0 and 44.0 'seemed' alright judging from the fired cases. 45.0 threw a primer and stuck the bolt pretty snug. Obviously the rest of those are coming apart. I've leaned pretty hard with H414 in other cases with never a primer doing that. Apparently it isn't a good match in the Swede.
