Shooting my 6.5 Grendel at 600 yards.

[Howa]

I had the very rare opportunity to shoot my CZ MTR 6.5 Grendel further than 200 yards recently.
The range was 600 yards long, the weather very hot.
I shot bullets comprising of Lapua cases, 28.0 gr Tac powder, CCI BR 400 small rifle primers with a 107gr Sierra Matchking.
The rifle performed well, could have had better accuracy if I had a better organised prone firing position, I usually shoot from a table nowadays.
A very enjoyable day though with good companions, their knowledge and equipment was tremendous and an eye opener for me as shooting at 200 yards mostly not the best for acquiring the knowledge for shooting greater distances.
Such a pity that in the UK the opportunity to shoot farther distances is so limited.

You need to come over to Montana.
Grendel gets used to 900 yards on MOA steel plates. I have not shot Sierra 107's as they are hard to come by, but I have thousands of 123 grain Nosler Custom Competitions I use for such fun. One bullet that I have a great number of is the PPU 120 grain HP "Match" sold here a decade of so back. I have a smokingly accurate load for them in my dated, obsolete, 6.5 x (whatever) Swedes and so I reserved the remaining 1200 of them in my inventory for that purpose. Should give them a run in the Grendle as other 120's perform very well at all ranges.
What speeds were you getting with the 107's? Have a chance to Chronograph them?? ~Muir

Thanks for your reply Muir, I was hoping you would as I have read from you your liking of the 6.56 Grendel.
Wish I could get to Montana!
Good to hear that the Grendel can get to 900 yards as I have the chance later this year to shoot a 900 meter range (1000yards), and I was wondering if my load using 107 Sierra M/kings would have the legs?
I was wondering too the effect of using a higher weight bullet on the velocity and how it would carry?
I would be interested in your view as to switch to a higher weight bullet or stick to the 107gr for this forth coming range day?
I'm very interested to read of your PPU 120gr HP Match for your Swede, your load with these would be very interesting.
I have a 1917 Swede in superb condition (all part numbers matching) what workmanship!
It may sound like sacrilege but I've fitted it with a Vortex scout scope(I have retained of course the Iron battle sights)
I currently run it with PPU 139gr, which was partly the reason for the scope, with Sierra M/kings excellent performance.
No chance to obtain the speed yesterday, would have been interesting.
P.s.
Very impressed with the alongside shooter to me, he was firing a 6.5x47 in a tactical rig, highly accurate.

I would go with the higher weight bullet for wind résistance. With that load of TAC (around 2400 fps?) your Sierra 107 has a BC of around .420. The Nosler 123 grain CC is around .510. I can touch 2700 fps with Lovex fuel.
Get your load chronographed. Buy one. Borrow one. You're working in the dark, otherwise.

As to the Swede. I use a terribly inefficient load of IMR7828 SSC. Shoots very small groups. ~Muir
