Please elaborate a little more on this.

Thanks,

Don't want to talk for BB but let me chime in.

Take a standard 2.820" long magazine. Some may vary in length, but, hopefully, you get my meaning. The 260 Rem case is 2.035" long with a standard 2.8" seated bullet OAL per Wikipedia. The 6.5 Creedmoor case is 1.920" long with a standard 2.820" seated bullet OAL per Wikipedia. The 6.5x47 case is 1.843" long with a standard 1.736" seated OAL, per Lapua.

When seated to the standard OAL, the shorter cartridges are going to be able to "chase" the lands as the throat wears out through out the life of the barrel. In a longer cartridge, such as the 260 Rem, one might not be able to chase the lands since the standard OAL is already at the max for the magazine anyway.

My sniper grade 6.5x47 with 2200+ rounds, when using the Berger 140 Hybrid seated at .015" off the lands, where it likes to be, is at 2.85"; beyond the standard length for most magazine any way. Fortuneately, the AI mag length accommodates this.

Help much?

Alan
