I created a thread a while back concerning a youth deer rifle: https://www.thehighroad.org/index.php?threads/deer-rifle-for-12-13-yo-6-5-grendel.842847/

I acquired a CZ 527 in 6.5 Grendel and the reloading parts I needed. The rifle is very beautiful -- much better looking than the Howa I handled at the store. The walnut and the metal finish does not disappoint at all.

I haven't adjusted the trigger, but I'm pretty happy with it, especially when using the set trigger feature. I shoot paper plates and I'm able to stay on the plate at 200 yards. I figure that's pretty good considering I'm not well-practiced in riflecraft and I just put the cartridges together with new, unprepped Starline brass, the cheapest Speer bullet (I'll be hunting with Barnes), Hodgdon's starting load of H335 and set the OAL to fit the magazine. I'll be working on improving my skill and cartridge quality.

There's a few things not to like. At first I was indifferent toward the detachable magazine, but when I started actually loading it I realized what's wrong with it. A detachable magazine has fingers that keep the cartridges from popping out when the magazine is released. Those fingers keep you from simply pushing a cartridge in from the top, and since it's a Mauser-style action, you can't just push a cartridge into the chamber, it has to feed from below the extractor claw. Ok, so to load a cartridge, it looks like you have to detach magazine, load cartridge, and re-insert magazine. I do prefer the Mauser action over the Rem 700, but I like it where I can just push the cartridges into the magazine from the top. I can adapt though, not a big deal.

As I said before, the walnut stock is gorgeous, but the LOP is an inch too short for me and it already has a fairly thick recoil pad on it. It's too long for my sons who need it about 3/4 to an and inch and a half less. The rifle comes with rings that mount on the dovetailed receiver, but they're fairly tall to clear the 90-degree bolt-throw. I find the comb is not quite high enough when the scope is that high.

Since I intend to share the rifle with my wife and two boys, I'll probably get a Boyd's At One adjustable stock. When I acquire more rifles, I'd rather have a beautiful-looking stock on it just like the one it has now, but I don't know if I'll go with lower rings and change the bolt handle or a higher comb and different LOP. Like I said, for now it'll be shared. Deer tags in my state are issued for "party hunts" and elk, antelope, and sheep are all by individual lottery, so the whole family is putting in for tags next season and they've got to shoot their own, whatever we draw.

I don't have any experience on game with the Grendel yet, but reloading it has been a pleasure. I ordered shell holders for it, but it turns out Grendel works perfectly with .357 shell holders and vice-versa. I was also able to adjust the shell feeder on my Lee ABLP to feed both .357 and Grendel without any adjustments -- they're very similar in both diameter and length. So changing over is as simple as swapping 1/3 turn breech lock dies and powder measure and I can load Grendel on the progressive press that's usually churning out .357

I haven't introduced the boys to it yet. I need to get it to fit their LOP for the best experience. They'll be working on marksmanship through the summer, and they'll probably get started with Coyotes. I think they'll be well-equipped for deer next season. I would absolutely consider another CZ 527 in Grendel, a semi-auto Grendel MSR, or another CZ -- very happy on all accounts.
 
I have been wanting theme to come out with this combo forever. A flat shooting cheap plinking round with a quality bolt carbine in a walnut stock .
 
Custom bolt handles are the way to go for these rifles if you want to mount a scope low on the receiver, and a lot of scopes look too big on them. That's my only complaint with my 7.62x39 carbine, but I don't really want a scope on it anyway.

If you want to single feed the rifle just drop a round in the chamber and close the bolt on it while pressing on the center of the extractor mid bolt. It will pop over the rim just fine. It is a pain to pull the mag to feed a round, but the modified mauser extractor will let you cheat a little bit.
 
Adcoch1 beat me to it, but I single load all the time. You’ve got a great rifle. I have two, one I built from the receiver up and another I bought. The one I purchased will benefit from being bedded.

XBR 8208 is my go to powder for bullets over 100 grains. I’d recommend you try it next time you need some powder

Labnoti, if you’re interested in selling the stock, let me know. I have a second receiver I plan on adding a barrel to in 2019 and I’ll need a stock.
 
Haven't shot my grendel enough, but I love it. Mines an AR though. Ditto on the XBR 8208 powder. Lots of super high BC projectiles available for 6.5 too. With the bolt gun, you can take advantage of them, especially the Berger vld and similar bullets.
 
What's better about XBR 8208? Does it just meter more accurately as a short-grained extruded powder vs. a flattened ball powder like H335? Or is there something else about it? Barnes has limited data for the 100 grain TTSX I intend to hunt with, but it does include both H335 and XBR 8208. They recommend Reloader 15, but unless I have a reason to choose otherwise, I usually get the USA-made ball powders.

I'll have to try the flipper feature on the extractor claw. Thanks for the heads up.
 
Labnoti, please note I use 8208 on heavier bullets. Until this last post you didn’t give a bullet weight. I sometimes shoot 100 grain BTs and use H335 for those, so that may work well for you. Different bullet weight often perform better with different powders, and 8208 seems to be the preferred powder for heavier bullets.

I’ve used the Barnes bullets and H335 combo you’re using in both my Grendels.

XBR 8208 works great for me up to 120 grain bullets. 123's start to open up and it doesn't like 130's. I tried LeverEvolution powder (yes, the one designed for the 30-30) on advice from some guys on the 6.5 Grendel forums, and it is simply fantastic for 123 and up weight bullets. Much better groups, velocity and lower pressure. I was a bit disappointed to find this out since I have about 7 lbs. of 8208 handy, that I use for my 7mm-08, but I can still use it for the lighter bullets. The 6.5 G is a cinch to load for.

After reading your initial post, I am glad I have my Howa Mini. I ran into the same single load issues with my Ruger 77's, and it proved to be a real PITA after a while. Now that Brownells is offering a walnut stock for the Howa mini actions, I think that's the overall better buy in a bolt action 6.5 Grendel, although I do like the CZ's a lot.
 
To be sure, the thing I didn't like about the Howa I handled was it was painted or coated green -- the whole thing. I suppose it could be practical but I didn't care for the looks.

From what I've read further about XBR 8208 is the advantage is in temperature stability, with a focus on bench-rest shooting. I'm sure it's good for that purpose and others, but my criteria are probably lower and I won't run out of H335 soon.

I'm not sure my rifle has this feature. I checked out the extractor on my CZ 527 American and I don't see how it can be pressed or pop over the rim of a chambered cartridge. I had a misfeed and I pressed a cartridge into the chamber with the bolt and without the extractor claw around the rim. I couldn't find any way to get it to pop over the rim. The cartridge wouldn't shake out either. I pulled the bolt out and I had to drop a rod down the muzzle to push the cartridge out. I'd love to know more about how this trick works.

it could be on the older one's they did not jump over the rim. there are 2 thing that have to be done with a crf action, one is the extractor needs to be shaped properly to ride up over the rim. and the other is there has to be clearince for the extractor to move freely. i could be that case's rim ws bigger the spec. i wish u could top loads these, the 7.62x39 would be even cooler if u can use sks clips to load.

So I was out shooting the cz the other day, and my brass plinker reloads wouldn't let the extractor pop over them, but the steel case would. You push on the extractor mid bolt with your thumb while closing the bolt with your other hand. Don't remember the headstamp on the brass but I think the rim is a little bigger than the steel case stuff. So maybe it doesn't work all the time.
