I picked up an old BSA Monarch a while back in 6.5 X 55, anyone know off hand what the twist rate is in these rifles? The reason I ask is I have approx 3000 156 gn dual diameter Norma FMJ nickel jacketed bullets designed for the 96 Swede. I'm hoping it might shoot them.
BSA Monarch rifling twist?

Thanks much Kevan for the info, 1-8.66 will be marginal for these bullets but if I can give them another 100 fps over the old swedes ballistics it might be enough to fly 'em true. I too have a lovely couple of these babies. The other one is in 270 Wby, no I didn't do this to it I bought it this way, but do not despair a change is in the wind.
Kevan. I was a bit surprised to hear you say that the 6.5x55 has RH twist.
I have owned a number of BSA rifles over the years, and invariably they had LH twist barrels. [6mm, 257R, 270, 30-06]
However, I never had one in 6.5mm, so perhaps different machinery or an outsourced barrel?
