G1 BC for Lapua 139g Scenar?

[Tim K]

Can't find 142 SMK's, so I'm thinking I may have to switch to the Scenars. The BC's are listed as G7's. Anyone know the G1 of the Scenar? Better or worse than the 142 SMK?

.590 ish just like the 142s , pretty much interchangeable . The Scenar's tend to build pressure faster than the SMK's .

Thanks Chuck. I guess I'd better order some.

Website shows .578 to be exact so right between the 140 and 142 SMK's but they seem to work great in mine so far.
