Home Forums Hunting & Shooting Custom Rifles & Wildcats Building a 22 Grendel on a Howa Mini

I am considering doing this.

Does anyone know if I would be able to play with 88+gr bullets while keeping the base of the bullet out of the case body? Basically will mag length greatly effect seating depth?

Thanks

Well you will have 2.310 mag length. So get case length dimensions and the length of the bullet you want to use the most and do some subtraction.

Thanks. I had read a couple different numbers for mag length.

My Grendel's magazine measured that and I was able to reach the lands with a few different bullets. However most bullets did reach into the powder space a bit.

I'm guessing you are shooting a 6.5 Grendel?

FWIW, Tromix makes Savage style barrel nuts for the Howa Mini action.

Thank you. I had no clue.

I’m not sure why you want to neck down 6.5 Grendel brass. You’re simply recreating the 22 PPC. Both use the 220 Russian as their parent case. I think at this time Norma among others have 22 PPC brass. I’m sure you could use 6.5 Grendel brass as well. In the end you’ll end up with a 22 PPC or close variant.

Go with either one of the new BDL floor plates from Oregunsmithing or Jefferson Outdoor and you can extend coal to 2.48. The factory mag will limit you to 2.3 something.

Depending on the reamer used that will allow an 88 to stay out of the powder column. Idk who makes AR15performance’s reamer but it’s throated for the 88’s to feed out of ar mag confines.

22grendel, LBC, 224 predator is plenty of enough oomph over the straight ppc and is worth the hassle.

The 224 Grendel is where it's at...though I enjoy you CLUELESS fhuqktards doing your best. Hint. Congratulations?!?

A few thousand words. Hint.





A few thousand more. Re-hint.





'Course I shoot multiple rifles in 243 Grendel too. Pass the 88's in 224,over the 243 and 264 versions of same.

Hint.

Thank me later.

Just sayin'..................

Stick -

Those look like the Howa mag. Are those the 88s in there with room to spare? According to math, which sucks, those 88s and the SMKs should fit with a little room to spare. Also, what twist are you shooting and would you use something else? Lastly, what are your thoughts on barrel length? I'm thinking 24-26.

I'd wager,that it is in fact an OEM Hower mag. You'll NEVER go wrong,by siumply building a Dummy,with the boolit of intent and having the platform throated to same. Hint.

I like 7" RPM,due my atmosphere,others could likely get away with less...but Reserve RPM is your friend. Hint.

I'd not want anything longer than 22" and have multiple 20's which I LOVE. I'll take Handy/Dandy and let others use (2) "clicks" less on an erector at 1000yds+,as that is a GOOD fhuqking trade in my book. It is a modest cartridge,that boasts fhuqking exceptional brass(Lapua). Hornady fhuqking sucks,as do Norma and Starline smokes both. Hint.





KILLER fhuqking cartridge.

Hint...................

I’ve done the 20, 224, 243, and 6.5 on the Howa Mini. Makes a great little package with any one of them. The 22 Grendel is closer to the BR in capacity than the PPC as it’s shoulder is pushed forward.070” over the PPC. Data lies somewhere in between the two. I’ve only shot the 50TSX and 53 Vmax in the 224 and it was at 3500fps for both. Killed one hog in TX at 190yards with the TSX and one 120lb doe at about the same distance. Did a great job with both. I don’t personally need heavies in it for a light walk about rifle and choose PBR and easy holdovers for coyotes n deer.

Great youth rifle too.

I shoot Hornet,KHorn,Deuce,223,223AI,224 Grendel,22BR,224Wby,22-250,22-250AI,Speedmire and Swift. Hint.

The 88's .545BC is plum handy and it has a pile driving ass,that the TSX can only DREAM about. It really don't care about distance,atmospherics or shot angle...especially in Grendel. I choose a scope that steers boolits and gawking through same,will get an 88 wellllll past the 1000yd line. PBR is a Brew for Bums. Hint.

In this morning's atmosphere,an 88 outta a 21" 223 SALAMI is Supersonic to 1200yds+ and the reticle alone,will easily reach the 1000yd line. Boolits matter far more than headstamps.

Hint......................

I don’t see the need to quote or entertain theoretical b.s. of 600-1000yards with a 6 lb ‘hunting’ rifle. But feel free to carry on (as if that’s even a question).

Facts & Physics aren't "Theories". Bullets simply matter wayyyyyyyy more than headstamps and Ping Pong Balls do no favors,if only to the chagrin of Window Licking CLUELESS Fhuqks everywhere. Hint. Congratulations?!?

Now had the Thread been Titled "Dumbest Fhuqking Bullet Possible In 224 Grendel",you'd be doing exceedingly well...but alas. Nor is there a lineal extrapolation,from a platform's mass,to it's transonic slip distance. Hint.

Say something about glass,PBR and how you correlate POA/POI,if only to add more oblivious humor to the equation. An Illuminatti only has 10 Mils on the etched windshield and another 62 on the erector. Google it all and be sure to TRY again. Hint.

Bless your heart,for doing your best.

Hint.

LAUGHING!..................

Some additional info on the utility of dummy rounds:

Interested to hear how it goes. Bought a couple Grendels recently, PSA build and a Howa Mini on the way. Going to shoot both as is, but the plan was always to see about 22 Grendel once the heat(wife) died down.

My Grendel is extremely accurate and still only 5 1/2lbs bare. I repurposed lightweight Heym barrel blanks from Numrich. Exceptional barrels not considering the $50 I paid for them. Light hunting rifle shooting worthless ping pong balls apparently.

I'm rather enjoying The Hurt Feelers Report(s) and am VERY "surprised",that glass,mounts and POA/POI correlations are given THE widest of fhuqking berths. Hint. Congratulations?!?

If only for conversation,a 50/53gr launcher at 3500fps is called a "223" and pardon my having a "few". Launchers of same at 3700fps+ are called "223 AI's" and I've a "few"...though "only" in 7,7.5,7.7,8,9,10,12 and 14" RPM. Were I forced to speculate,i'd venture that a few boolits have been squirted down them spouts and are easily extrapolated,if only on the same day,in like conditions. Hint.

Just a brief smattering of boolits for same,here. Hint.



Mighta' been a 50/53 used here,but prolly wasn't(75HPBT) in OEM spout punched 223AI. Lighter than 5.5# bare. Hint.



Mighta' been a 50/53 used here,but prolly wasn't(75'Max). Lighter than 5.5# bare,,with the Mike Rock 7" RPM 223AI contour dupe at 21" and reduced shank,to replace the spent OEM spout. Hint.



Scope puked,then the LW's puked(though in fairness,I've only had 8 sets do same,thus far). Hint.



MUCH better. Hint.



Same thing happened here. Hint.



But I shot that barrel out(Brux 8" RPM now and in 270 for 105 HPBT's) and it actually cain't be too far away,from needing it's 3rd. Hint.



Grab another Hurt Feelers Report,fill it out and "tell" me "more",because you really "know" your "stuff" and are "rugged" to boot. Hint. LAUGHING!

Bless your heart for fhuqking TRYING your best,because that is the ONLY fhuqking reason it's sooooooooo fhuqking hilarious!

Hint.
