feersum,
If you never plan to shoot much beyond 300 yards the SMK 168 is a great choice... but then it was designed as a 300 meter comp bullet. Beyond 300 the wind becomes a big factor and bullets with a higher BC will perform better.
I shoot a lot of 600 yard competition using a Match M1. I have a "loaded" model M1A but I don't shoot it in comps. Have shot it at 600 for fun-practice.
In both rifles the SMK 168 is a very good bullet out to 300 and decent at 600. The SMK 175 is MUCH better at 600. The JLK 175 VLD is better still..... but then, looking at my taglines you'd expect me to say that.
The 4 match aggregate score I refer to in my tagline was shot with my SA Match M1, 1-10" twist .308 Wilson barrel with (At that time.) 4.5K rounds downrange, and the JLK 175 VLD over Re-15.
In August of this year at the Planet Matches I used this same rifle (Now with over 5k rounds out.) to shoot a 600 yard score of 199-10X. Same bullet and load.
Best regards,
Swampy
Garands forever

The difference between a Hot Dog and a Weenie is a very fine line.
