Lapua .308 projectiles

Just picked up a load of stuff that includes a box of lapua mira 186 gr soft point .308 projectiles. There were also 20 hand loaded rounds of lapua 7.62x51 brass with this projectile that supposedly were meant to go with a p14 actioned target rifle. Cant find anything on the lapua web sight about these, has anyone used them or heard of them. They are a bit of an unusual shape and 186 grs appears to be an odd weight. Any ideas anyone

Lapua MIRA 185 grain BTSP 30 cal
Ballistic coefficient = 0.458

Thanks, going to try some over 41gr of 2208 will make a change from 165 gr gamekings
