Hey guys,
Can I get a list of projectiles/powders you used and the results for a 6.5g ? Preferably from shortened barrell rifles.
Really appreciated,
Additionally, what would you throw out a short barrel 6.5g to target fallow/red deer head shots??
Thanks
Lars
I used Bm8208 and 123gr ELD-M or matchkings in the grendel I had. Shot extremely well. That was in a 18" barrelled rifle(unfortunately sacrificed in the name of public safety).
Thabks nzshoota, do you remember what amount if bm8208you used? Might help me start with a base figure atleast :)
Currently, Benchmark 8208 for 100gr and up, and Benchmark 2 for anything under. I'm also going to try SMP 763 with 130's once the range re-opens. H335 has also worked very well for me in the past.
I've had one Grendel that would show pressure signs when approaching anything close to max, and another that scoffs at "max" and begs for more powder. I suspect subtle variations in chamber design (Grendel has been through a couple of iterations) play a large part in this. Hence, as with any cartridge, but especially this one, you should absolutely be doing your own workup.
Both mine were/are 20". Whilst some point out that the faster powders finish burning in much shorter barrels and they get acceptable speeds, the pressure curve is still accelerating the bullet beyond the point where combustion finishes, so having more barrel still helps eek out the maximum potential of the cartridge (or at the very least gets those same acceptable speeds with less pressure).
IMO, this is important with Grendel, depending on what you want to use it for, because unlike say a short barrelled 308 - which will still lob bullets with enough speed/energy to put stuff down cleanly well beyond the limit of the average shooters ability, say 400-500m - Grendel's effective range on larger game is already less than that. So the more speed you can retain, the more you'll find yourself limited by what you can do vs what the cartridge can.
Keep it as long as you can :thumbsup:

90gn Speer hp in front of 26gns of 2207 for a little over 2800fps out of a 20inch barreled Howa mini action stainless. Very accurate & deadly on goats & deer.
They don't go far except down.
Agree, those 90 gn tnt and 2207 are a great combo and cheap.Quote:

And I use rl26 for my 300wm and my 6 5 prc.
Would the n150 or the 2217 be any good iut if a short barrell 6.5 g? Is it safe to try these sorts if powders?
I'm interested to hear what sort of shots you've been successful with on deer with this bullet? Given its sold by Speer as a TNT ie soft and explody (it's a word!) you wouldn't expect it to hold together that well? I realise that real world experience and labels/marketing terms often don't align. And the lower speed range of the Grendel must help in this regard?Quote:

No, they're both far too slow. Safe? Probably. Pointless? Absolutely. Go grab yourself some Benchmark 8208.Quote:

I mainly go for the lung shot (broadside) as they're a varmint proj as you say, so if it hits a rib it pulverises the internal tissue so they don't go far. If it's close that I can neck or head shoot (my eyes aren't getting any better due to age) then the result's = lights out for them.Quote:

Cfe223 was the go to in my old howa which I sold
I have another howa Grendel on order a heavy barrel one
Cfe223 will be the 1st powder I try when it arrives
Alot of good info on www.65Grendel.com

I'm going for cfe223 behind some hornady 95g vmax, have a few 120g eldmatch, and a few 129g interlocks to try also. So out of those will hopfully have a good load.
@Larskramer how did you get on with your load development?
Did you have much success with the CFE223 & 120gr combination?
Be care full with cfe223 in the summer it will spike, better off using 8208 with the 120 class projectiles.Quote:

So far getting 2575fps with small magnum primers cfe223 and 95g hornady eldv
Thats pretty slow, i did some testing a few weeks ago with 90gr TNT's with 8208 and was just shy of 2900 fps from a 22" Howa MiniQuote:

So what Velocities are people getting out of a 120-123gr Howa Mini 20" + DPT Over Barrel Suppressor?
I would be happy with the 120gr Barnes TTSX BT doing just over 2500fps if possible.
Barnes would be too hard unless at point blank or there of. 123 ELDM or SST will give you what you are looking for. I get close to 2500 from a 17" barrel & DPT. Another option could be Nosler BT. Use BM8208 powder and BR4 primer.Quote:

At the 100m mark, I have had a couple of pass throughs with not much expansion with ELD-M's.
Wanting to try something that opens up a bit more, and had heard good things about the Barnes TTSX BT.
Barnes need velocity to perform correctly. Pass through can happen with any bullet that doesn't hit something solid enough, like bone. I found the SST pretty good, though can be messy too.Quote:

Go to 6.5 grendel .com and a guy there has some great videos of him culling hogs, he rates it as the best bullet ever for hogs.
He also rates the 123 sst .
The 123 eldm opens up awesome, i shot a fallow in the base of the neck at just over 100 yards, the exit hole was big enough to fit my fist in.
I'm even getting 2400fps out of hornady black factory loads. 16" how a mini heavy barrel.
@Larskramer I need to Chrono mine, I recon from the rough reverse drop data I have worked out, I am only getting 2350fps.
Hornady Black factory loads. 20" howa mini standard barrel + DPT overbarrel.
tried a new load out today 30gr 2217 85gr sierra hp nice little 1/2" groups at 100m without trying to hard that will do me havnt chronyd it yet and cant put pics up anymore either. i also put small pillars in the bottom plastic which has improved it as well
My guess... pedestrian.Quote:

As your bullet gets lighter, your powder should get faster, so you're going the wrong way.
the only other powder ive got is lil gun but that might blow my gun up im experimenting with the powders i have on hand as i dont really want to but it looks like im going to end up with 200000 different powders. I also realise theres no 1 powder for every thing out of the powders on hand to try i have 2206h 2208 2209 2217 2219 and lil gun and cfe
2219 will work great, why don't you use that?
sorry thought something didnt sound right had another look at the label on the ammo box and my retarded 9 looks like a 7 :XD:
had a quick shot over the chrony using 30gr 2219 85gr sierra hp 2835fps av
I've got a mate who I'm going to shout some rounds for his grendel.
So for his purposes( fallow, reds, goats etc).
I was looking at the 107gr Sierra TMK. They do a 130gr version but I cant find any 107s ?
My theory was drive a 107gr TMK slightly quicker and being that their a relatively soft bullet from my experience in 7mm and 30cal so from Grendel velocities they'd be a good all rounder?
I've found these seem to hang together ok I've only dug them out of a clay bank tho. I want to get it dailed in first tho it's a neat little round but as with any caliber you have to be mindful of its limitations.150 would be my max for shooting animals with any caliber and that should be well within the limits of the grendel
