Thread: 6.5 Grendel Bolt action

Very nice

Make sure you try Bench Mark 8208

I love my grendel mate cfe223 is the best power
I know you have gone for a slightly different version which is all good
Plenty of good variations of the chambering
Theres a kiwi guy on the 65grendel forum
I think hes on here aswell von gruff who made his own reamer he calls 6.5gm (Grendel-max)
Just gives a little more power capacity and a bit more speed as a result
Just a fire forming from factory grendel brass as I understand could be worng

Look forward to hearing your results

@Mathias, you need to update where your at with the rifle.

Very, very cool

Ok, here we go then as per request.

The original MAB barrel didn't go so well as it had fault with a slightly tapered bore, so it got redone with a Hardy barrel, which has been excellent. As mentioned in another thread, making these buggers feed is really tricky, especially when the mag and action were designed for a 222. After a lot of fiddling with dummy rounds and various parts I now have it cycling 4 rounds out of the mag well enough to be reliable.
Key points I found were having the correct mag follower and the mag spring in right location on bottom metal to apply correct pressure. Running the wider follower means it won't pass through the opening in the bottom metal when plate is released, so all I do to unload the mag is release the mag floor plate to take the pressure off and turn the rifle upside down and the rounds come out of action opening into my hand, or I can simply cycle them through the action.

Mag spring to rear of floor plate.

The measured seating length for this baby and 123gr SST was 58.3mm but to be able to eject a loaded round I had to go back to 57mm OAL, which is the SAAMI loaded length. This made zero difference to how it shot.

At 57mm, it just makes it out.


There's plenty of ejector blade length once bolt is on its stop and shorting it will alter the timing and allow me a little more loaded OAL but it shoots well now and feeds well at this length.


Accuracy it great for a hunting rifle. These are 2 groups of 3 shot by my son, one is the hand loaded 123gr SST (2450 fps) and the other is Hornady factory 123 Amax (2505 fps).


Hornady factory 123gr Amax I shot when setting scope up.


This rifle is fun to carry & shoot and has plenty of power for filling the freezer.

Awesome... what did you paint the stug stock with?

After remodelling it, I primed it in 2 pack epoxy primer and sanded it back ready for Cerakote. I asked the company that did it not to garnet blast it before coating as this would blow out some if the filled pits, but they didn't listen it seemed and as a result it came out less than perfect, which pissed me off. However the Cerakote OD Green has stood up to it well and remains fully coated despite numerous trips on the quad bike rack and dragged through the matagouri and shit.

I've just bought one of the CZ 527 in 6.5 Grendel, only got a few rounds threw it, before being shut down for Coivid, the few rounds look like I may have a decent shooter, I cut it back to 18-20, but am going to see what sort of performance the 24" barrel gives first.
might build up a few varmint rounds, and see how it performs, on the local snowshoe hare's, and coyotes.
Ive got a couple Sako PPC and was going to rebarrel to a faster twist as the 1-14 on a 6ppc limits the hunting bullets somewhat.
we shall see how this little CZ goes first.

Nice, what bullet will you look to run for varmints? Ive only run 123's in my 6.5G thus far, only shot deer so far, but having a crack at varmints with it with lighter pills going a bit quicker could be fun too.

Am looking at the 95 v-max. But already a serious shortage of reloading components, due to panic buying in USA and Canada, am yet to find any, got a 150, 100g ballistic tips, kinda expensive for shooting small game, and a 100 Serria 107 gr TMK
should zip along with 24" tube, quick loadwith 3031 looks very good, as does initial testing.
I've been using my Sako 6Ppc for a predator, rifle, I've called in a wolf a few times now, and it's a bit light, so have passed on the shot,

Awesome, I always wanted a 7.62X39 on the little Sako Vixen/A1 action, but don't know if they did a PPC on that action or only on the S491 ?

Decided to do a .357 Max rimmless instead but may do a .350 Legend now ?

Thank you for posting your work .

The very first of the PPC's were made on the A1 action, then S491 and 75 after that. A 30ARX (30-6.5 Grendel) would be a squeeze but a nice round also for the Sako.

Scout: Sako did several models of PPC (6mm and 22) on the A1 action for a short time: sporter, heavy barrel with target trigger and single shot with target trigger. They turn up on Trademe now and again wanting silly money. Some internet chat indicates that the S491 will tolerate heavier loads than the smaller A1 action. Be careful to check the interior of the barrel if it is the original chrome moly barrel. I bought the heavy barrel with the target trigger model, second hand, and it would not group any better than 0.75 of an inch for 5 shots at 100m. The borescope showed that the barrel interior had corrosion on one side. The gunsmith who replaced the barrel was not surprised. He told me that a shipment of Sako rifles arrived in NZ with corroded barrel interiors and mine was in that time slot.

Interesting, thanks guys, I think in the past I had seen a A1 in a PPC cartridge but it was a single shot, I will keep my ears open for a A1 PPC repeater then .

Yay all I can say is long live 6.5 Grendel

I now have a howa mini in 6.5 G awaiting range trip etc after the WuFlu quarantine is relaxed.
