You are right about that! As long as the barrel twist matches up it apprears to want to shoot them.

I've heard of a fat rat and a big mouse. As the names imply, not much difference.
Had a quick session this morning playing with seating depths. This one certainly looks good. Won't have another testing session until next week prior to my first 600 yard match. This was shot at 500 yards 3-5 mph winds with 103 gr Dominators with the Grinch.
As long as the 40 turbo or the fat rat has been around I would really be surprised that dean hasn't seen one or heard of it I found this print on line with a Google search it's not the freebore I shoot but I have beat a lot of bolt rifles at the long range varmint game with this round out to 850 yds!
my friend and I both built these just to see what we could with them
The best part is they are both AR15 's we shoot a bipod but the rules are no rear support other than your hand this gun will shoot right with my 6 BRX it's the craziest thing I've seen in a long time. I also shoot it in tactical matches. It won the NOR-NEV match in June 2016 I started with a Kreiger barrel 1in 8 twist 2inch extended gas system after 2000 rounds my groups started to open up so I set it back 2inches went with a standard rifle length gas system and I am getting close to 2000 rounds again I get about 12 firings out of my brass, Lapua I will post the typical groups I get when I do a zero check before a match

Elvin,
You might not believe this but most of us Benchrester types pay no attention to what's going on in the AR World. I've been shooting Benchrest for 25 years and never heard of it. But I will tell you what! I have a buddy who's had a reamer that's a Grendel case necked down to a 6MM. He's had it for probably 12 years or more. That very well may predate all the fat rats, and turbo rats, skinny mouses or whatever else might be out there.
I've yet to have anyone send me a print. I'll bet you they are similar but not the same.
Good shooting though!
Bart

What powders are being used for Grinch + 80's? Any different for Grinch + 103/105s?
Thought I saw a reference to N135 somewhere. Is N135 similar to H4895?
thanks,

With the 80 gr bullets we have pretty much used powders that we use in the 6ppc such as v133 and 8208! We shot some V135 and it seems to work as well!
With the heavier bullets it's been RL 15, Varget, 4895. We haven't shot much of the 135 yet with the heavier bullet! But it will probably work to.

Bart, thanks for update!
Friend found and sent me this older post that referenced V135 (this is probably what I saw earlier but couldn't find it). Looks like V135 was listed "better" than V133? If I had to pick one for 80gr, which one would you suggest? V133 or V135?
thanks!

Thanks! I'll give V135 a try.
I tried looking on the Vihtavuori website - but nothing on temperature sensitivity - so appreciate the response. I did find a sentence that says V135 "...fit applications similar to IMR4064, Hodgdon H4895 or Accurate 2520."
Does that mean if you have something that works with V135 - one can substitute with H4895? Although it might be "similar" - I'm guessing any accuracy seen with V135 may or may not be realized by switching to H4895? Sorry for the newbie questions.
I would think 8208 to be just about perfect for the 80's, in this cartridge. We'll see pretty soon.
