6.5mm Grendel
Posted: Fri Nov 04, 2022 7:29 pm
Just some thoughts that I responded to a guy asking me about my Grendel.
He is getting his young son started with this cartridge, someone else might find it useful.
I’m killing time waiting for my son to get out of auto shop class.
My load is:
107gr Sierra Matchkings
130gr Norma Golden Match
107's for first three and 130's for Rams
I use 27.0gr of IMR 8208 XBR powder and CCI 450m primers, very insensitive to temp changes.
My OAL for 107's is 2.350" and 130's is 2.450", smaller cartridges require more careful reloading.
Of course your chamber is probably different from mine.
My bolt's firing pin is "Bushed" which is they turn down the firing pin and close up the firing pin hole for a tighter fit.
This is to prevent primer flow into the firing pin hole.
This load works for me, but you should start at around 23-24 grains and slowly work up.
The Grendel doesn't like bullets heavier than 130's, you will only be disappointed.
I don't have any trouble with the first three animals, and have very good luck with the rams.
The key is to find a ram bullet that is very tough, thick jacket and as streamlined as possible.
The guys using the 6br’s normally drive the bullet too fast and they don't push the target over, they just blow up on impact.
No need to drive anything hard, the key is to keep the bullet in contact with the target for as long as possible, to PUSH it over.
I'm not a very good shooter, I only get to shoot this maybe 1 or 2 times a year, but I get this from my observations and plain old physics.
I would start them off with 107's for all four distances, then work your way up.
The idea is to start hitting them first.
Thanks, Dennis
