Stuart,
No mate, I'll be shooting the trusty BRX in the light rifle at Little River. The Grendel is basically an experiment at this point.

Stuart & Geoff,
 There have been similar cases around for some time now apparently. The 6mm AR Turbo is very close but I think there is a patent on the reamer. There's a 6mm fat rat & now the 6mm Grinch. From what I can tell they are all much of a muchness.
Luke from ProCal ordered a reamer to his specs & he is calling it the 6mm ProCal.

As a short range rifle the "Grinch" is kicking a few goals in the US with Bart's 80 grain dominators, a projectile that is supposedly very similar to Ken Melgaard's 6mm 80 grn flat base.

As a long range rifle it is also showing a lot of promise. Luke Easter (ProCal) shot the small group for the day at Batemans Bay earlier in the year using this case & in the US some people are using it in 6oo yard matches with good results.

Yes Geoff, the velocities are surprising with 103's & 2206H….I was expecting to max out at just over 2900. I'm hoping to find out what 2208 will do some time this week…. I have no idea, at this point about barrel erosion etc..with "mollied" projectiles I've run up in .1 grain increments from 29.5 to 31.1…so….I'm guessing that erosion will be about what 6PPC, 6 Dasher, BRX etc shooters  would consider to be normal, given the charge volume. Just a guess though.

Stand by,
Belly
