Looking for those who have a Grendel in a bolt gun, looks like a sweet possibility for the mini mauser, no mess feeds like built for it> Anyone? Thanks, Lynn
It is a great cartridge for the mini mauser even if I did lengthen the magazine on mine so I could push the shoulder of the cartridge forward my .05 and seat the bullet out so it was 2.405 COAL and gained case capacity and velocity. have taken a lot of animals with it. Great walkabout rifle but the bolt handle needs to be made longer with better bolt knob but that is not a difficult project. All in all I really am taken with this cartridge in the little action. In the pic the Grendel is in the center with my Grendel Max on the right with the same 123gn A Max as the Grendel and with a cast bullet as well.
This is no fancy gunsmithed rifle, just something I did for myself as cheaply as I could. 21 in TSE (Australian barrel) I bought an action minus the follower and extractor cheap ($80 NZ which about US$52)The follower and extractor were reasonably priced so it was still a cheap action as a base.
bolt mods done bydrilling and tapping into a short piece of 7/8in bolt shaft and chucking it in my drill, I was able to get a reasonable shape against the belt grinder
mag temporarily lengthened to the rear to check function
For the stock I made up a laminate but differing from the usual approach I started with a 15mm center core and slimmed it down from the action forward and back down through the wrist area so that when finished there would be a single lam going the full length of the stock with out cutting through the laminates. 15mm center core with 3 x 5mm laminates either side of the core plus an extra small piece to suit the bolt release Starting to lay up the laminates to make sure the bend cuts I have in the cramping boards will allow for best clamping.
For those interested, this was the reamer specs I sent to Mansons. I use standard Grendel dies but have fixed a permanent .05 spacer on top of my shell holder + a tempory .006 shim so that when I necked Grendel brass up and then back down I would have a false shoulder .006 longer than headspace to ensure crush fit fireforming and gave me fully formed cases. To get a headspace guage to set the barrel I hydroformed a case without the .006 shim and it worked to set the barrel on both my rifle and a friends (he is a professional pest animal shooter and has killed hundreds of goats with his.)
I have rebarreled many of these little actions and the little CZ actions also. They really make nice handy little rifles. The down side is that because these mini actions are mini and therefore weaker than their big brothers they probably shouldn't be loaded to as high pressure as the full size actions.

Try to look unimportant. Your enemy might be low on ammo.

There were offered in 22-250 as well as the 223 with the smaller case head so the larger case head of the Grendel or Grendel-max at the same pressure should have less back thrust so I am comfortable with my load levels
I had Sako A1 action (original 22PPC) barreled by 6,5mm Grendel barrel. And i really love it. Its really great short action. Its feed really smooth all ammo´s and accuracy is really great. I really recommed this Sako before CZ action.

Gruff: Bolt Thrust = Area x Peak chamber pressure. If a 223 and 6.5 Grendel are loaded to the same chamber pressure the bolt thrust would be less on the 223 case because of the smaller internal diameter of the case head. That is why the T/C contender was chambered in 223 Remington but not 308 Win.
Von Gruff: I am very interested in your mag box modification. Would you care to share the details? What follower did you use to fit the lengthened magazine box? Thanks.

The action was missing the follower when I got it and through a friend I got a Sako A1 follower which works very well. The mag box was lengthened to the rear by cutting the back wall out and welding in a replacement piece that allowed for an internal length of 2.470 and handles the 2.405 length easily.

Just saying. Be careful.

Love it! Would love to have one just like it! What are you shooting for Cast? How's it work? best regards,

The cast bullet is from a custom mould that Veral made for me but I was asked for the design and NOE is making it now.
It is 123gn lubed and gc,d and has proven quite a performer. A plinking load of 11gn blue dot gives it a velocity of 1650fps and groups into about 1 1/4 to 1 1/2 at 100 yds although the P O I is 2 right of the A Max zero but even with that there have been a few kills on goats out to near 150 yds to date. I have cast in a cu enriched alloy and run it to 2300fps but it went through 8 water containers and kept going with the exit from the last bottle the same size and the entrance in the first so have stuck to the 1650fps load as it works well enough for plinking and the odd kill as well.
Excellent! I have grown to love the cast bullets in my 30-06 and my 458 Win Mag but most of all the 35 Whelen. I have not killed anything in several years that did no die by Cast. I think the rifle you have there would be a very good game getting in the woods or other close in places. My old Whelen has killed a couple of whitetail at 250 yards or so. That using Bead and Peep and 280-90 grain RN Cast. I shoot them no differently than I did with 225 Grain X bullets. Put in though as much lung and bone as possible determined by their angle at the shot. They run a ways and expire. The benefit to me is I shoot so much more with it using Cast. It's just fun. Best regards Brother.

The 6.5 is my smallest cast bullet with this rifle and a 20 VarTarg being the only two that I shoot jacketed in. My 7x57 with a 160gn soft nosed/hard shanked cast bullet at 2415fps is a real performer and good to 200yds with the peep sights with quite a few kills in in the freezer to date. My 303 and 400 Lee Speed sporters as well as a 303 and 577-450 Martini all have steady cast diet and make range days a cheap and very pleasurable outing.
