I’m not a frequent poster to this forum, but a long-time reader, and I wanted to add to this post about the little 22 Grendel (yes, Grendel). About 10 or so years ago there was a fella at a range I shoot at who was a massive gun tinkerer with an awesome machine shop. He built a 22 Grendel on a Sako action fitted with a 24” med. sporter barrel in a 7tw. to shoot 80 grain pills. . .and it was an absolute killer!!! I was instantly in love, but never had the time nor the extra cash to put an experimental one together. Fast forward to two years ago, at an outdoor expo here in Florida and I what do I see at a both. . .none other than the most pretty little Howa 1500-Mini chambered in 22 ARC (yes, I had heard and read of Hornady’s creation by this time) with a 22” 7tw. barrel and a very nice fancy wood stock! Yup, it came home with me for $600.00, and another stop on the way home came 300 Starline 6.5 Grendel pieces of brass. There was searching online for dies that evening and I managed to source and put components together. . .rather pricey in my route of doing things, but I made it work.
I ended up glassing and pillar bedding the action in the wood stock and replacing the plastic bottom trigger guard/mag well with an aftermarket actual aluminum bottom metal. I would give almost anything to get rid of the gaudy magazine that Howa supplies with these rifles, but I’m stuck with it until a better mousetrap surfaces. To my surprise the accuracy of the 22” pencil barrel was quite good, although after a five-shot group it got pretty heated. After several powders tested I was able to settle on two, VV N540 and 2000-MR to give the best ES/SD, accuracy and velocity. I tried MANY brands of bullets from 77 to 88 grains as well; Sierra 77TMK/80SMK, Hornady 80ELD-M/88 ELD-M, Berger 80.5FB/85.5LRHT, Swift 75BT and Barnes 77LRX-BT. With some load development I was able to achieve 1 MOA or better with most all of them. On my radar is the Speer Gold Dot/Fusion 75 grain bonded bullet, wish it came in a 85 grainer.
Now on to my purpose. . .let the flaming begin-LOL!!! I LOOOOOVE bullet testing, just so you know. This thread here has been the talk of coyotes, and I kill everyone I get a crosshair on, but I’ve built my loads for mostly wild hog deprivation on crop fields and golf courses around where I live, and hunting deer. Yes, .224 centerfire cartridges are legal to use in Florida for deer as well as in Georgia. I am blessed to have locally a target rich environment and an unlimited supply of the BEST bullet test media there is – wild hogs! As many of you know, male hogs when they get a couple years on them turn into well built 35 gal. barrels with stubby legs and with their hide/hair, bone structure and gristle layer over the ribcage. . .what could show a bullets integrity any better! For testing purposes, I’ve kept my shots 100 yards to 250 yards respectively, chest/vital shots only, and to date with the Lil 22 Grendel/ARC I have dispatched 40+ hogs (80 to 200 lbs.) and 7 bucks (140 to 180 lbs.) between FL and GA, and ALL of which have dropped within sight – less than 30 yards with many bang-flops. Now I’m not stating this is the greatest whizz-bang Hammer of Thor, this is the ONLY cartridge you need to rush out and buy to any means, because it is far from that. I’m testing bullets/cartridges on live game at respectable distances on broadside or marginal quartering shots – I’m picking my shot placements – within a distance I feel comfortable with the bullet/cartridge performance, and wanting to share my experiences with others.
On to the meat and potatoes of my rant. I have RARELY experienced a pass-thru shot on these animals unless the bullet has not come in contact with a rib or other bone. Smallish hogs and one buck I did get a pass-thru on, and the only time sign of a blood trail if one had to follow – which is a down side. Exit wounds are good, when it happens. There is not even much if at all blood on the entrance hole. And if the animal has been eating a lot of acorns or in someone’s corn pile, it plugs things up instantly due to the internal mess inside. The internal damage is amazing, like if you were to insert a 5 gal. paint mixer bit into your drill and then the chest cavity, then mash the trigger. . .total Hollywood freak show inside! This is the reason I believe for my kill ratio/recovery distance with the .224 bullets.
Here is my load data for the two bullets I feel have given the best on-game performance. I have not shot any animals under 100 yards or over 250 yards, so these are the parameters I’ve worked in. I use a Leupold BX-4HD range finder to confirm distance and a Garmin Xero-C1 chronograph for load data. My shots have been off rests over my truck hood, on a tri-pod, or out of a shooting house – basically everything is rock steady. The Hornady 80gr. ELD-M and the Berger 85.5gr. LRHT have performed the best for me. I manly stick to the Hornady due to the ease of availability, but both bullets are damn near equals with all my criteria for my hunting.
** These loads are stout and shot from a bolt action rifle – my rifle. I would NOT try them in a gasser without dropping down in powder charge, your bolt head will suffer!!! **
