I have been thinking about it a little more. In the 24" barrel, the lands a 2.375. So if .020 off the lands 2.355 COAL with the windowed PRI mag which can be done, no problem in the 20", as the lands are .030 more. Based on that COAL, I recon I should be able to fit in another 1.5 grains of powder in the boiler room . So with the Hornady Match, load of 2,725 fps, after I barrel break I should be in the 2,760 or so area.. With 1.5 grains more capacity than the 2.26 load length , I m thinking 2,860 to 2,880 is a true attainable velocity in this 24" with PRI mags without getting crazy. For the 20" with this load, say I would guess around 2,740.
Using 2,875 as then hand load velocity, here is what I get drop and drift at 1,000 yds at sea level and 100 yd
8.28 mils drop
2.06 mills drift
For the 20" using 2,740
9.34 mils drop
2.23 mils drift
Comapred to a 88 gr ELD M form a 24" barrreled 22 ARC at 2,860 , 100 yd zero 10 mph crosswind wind
8.03 mils drop
1.94 mills drift
It is pretty dam respectable.
The 130 RDF is chugging along at roughly 2,590 fps. And the same variables
9.34 mils drop
1.98 mills drift
So 1.15 more mils drop with the 130 rdf. Drift is a little tighter, but .25 mills less wind drift.
So for a Grendel, the 100 gr ELD VT makes the rifle shine , as a varmint hunting and precision shooting platform. A lot flatter shooting with very respectabul wind drift for its weight. The bullet will be devastating on coyotes and barbiturates size game. Of all the Grendel based cartridges, this brings a lot of performance to the Grendel.
I'm still not going to get a 6 ARC or a 22 ARC, for that matter either. The 6.5 Grendel platform just offers so much in platform capabilities, varmit hunting, deer hunting, hog hunting etc ettc. You just load up a bullet that matches your performance envelope and away you go.
It will never be a PRS comp rifle, as you have got tons of better options. The 22 ARc shooting 90 gr ATips is pretty sweet, filling that role, but everything else except hunting varmits at ranges past 400 yds is in the Grendels wheel house. The small advantages the 6 ARC and 22 ARC have at long ranges don't really matter. I have other bolt action rifles for that.
So when I get a couple hundred 100 gr ElD VT bullets are start developing loads along these lines. Ill be back at you.
