.223 or 6x45?

Not really, I had a 6x45 and might wind up building another because of Virginia's 6mm or bigger for big game laws.

But honestly, I don't think it compares to a 223AI with 75s. The only thing it has going for it is the big bullets going slow dig a little deeper.

i find it easier to see 6mm impacts as a general rule.

but unless you got a pile of them stashed, good 6mm bullets are way harder to find then 88's or 75's

edited to say at a cheap price.

A whole nuther country
With the BC of 88’s I can’t see the need for a .243 bore unless I’m missing something
I snagged another Montana .223 and am thinking I’ll rebarrel it Sami .223 7T and fling 88’s at everything
Probably rebarrel my daughters same/same at the same time and hope they both like the same load

Good snag.

How does the 88 compare to the 75 inside 500 yards? I've never shot an 88 in 223 normal or AI.

I'm not sure its slumming at 223 velocities.

22 creed and 22-250 AI velocities may be another story

Like my 223ai with 75 amax a lot too. This one checks the box for minimum caliber in CO so can carry it and not worry. The mini rigs are seeing a lot more time here.

I'm in the same boat with the regs.
Every surrounding state allows 22s but apparently our VA deer are a tougher breed

The 270 with 105's,is EXCEPTIONALLY forgiving,from a Utility standpoint. They just simply dig and kill shit dead,less fanfare.

The .224" 88 is a NASTY Bitch and of course eeks more velocity,with a higher BC,for superior drop/drift and impact velocity values...none of which sucks.

One of my VERY Favoritest Rifles happens to be chambered 270 and flings 105's expressly out of it's 18" spout(Montucky). I've zero qualm pointing either at a Moose and depending on weather,just might(opens Saturday).

Neither chambering,with either projectile,can get itself in trouble,regarding terminal performance. The modest velocities jive nicely with their respective construction and there is nothing to fret. The 88 is ruggedly reliable in said velocity threshold and flies rather nicely. I've multiple rifles in each and stay very close to the18" 270,due the blueprint,as much as anything else.

Fucking LOVE that rifle................

i guess I've been living under a rock, but how fast does the 270 push the 105's, out of a 18" spout? I've currently got a .223 AI Halibut, but it's twisted 1-8". I have .378 and .472 700's on the shelf, and I'm contemplating a short barrelled utility gun. Likely mag fed, as there could be plenty of in and out of vehicles. I guess I'm thinking .223 spun 1-7", 270, or 6br, although I don't really want to have to fuck around with making things feed well.

Some things never change and THE Cardinal Rule is: Bullets matter way more than headstamps.

The .224" is always gonna have a much better BC,at anything resembling similar mass. For me,all I wanna shoot in a little guy,is 88's and their .545 BC. That is slicker than 105/8's in 6mm and they of course are traveling faster,out of like case capacity. Factor 2650fps in a Vanilla Little Guy 223,with same. No muss,no fuss and no bullshit. I still see Lapooey 223 brass on shelves,along with 88's.

AICS DBM allllllllllll the way for me. 1-7" for certain. I'd cut to the chase and bush the bolt,if talking OEM donor.

With all that being said,my crummy is warming up now and my Baby Montucky 270 is in the front seat. Why? It's S/S,short(18"),handy and I'm in LOVE with it. 5 in the belly,but modest work to increase COAL,as the magbox proper goes(700 milled follower too) and upon the bolt stop. Exhaust port is flared to boot. A 700 is Crazy Easy. AICS DBM and you are done.

As 22BR and 6BR go,it's the same extrapolation,as 88/90's and 105/8's go. Though NOTHING begs to please,like a 6BR. Again on a 700,simply AICS DBM and you are there. I bush those bolts too.

To set the stage,I'd simply opt AICS DBM on your existing Halibut and get your mind right upon same. AM steel 5-rounders for Default Utility and MDT Poly 10's as Herd Clips. A roundfile will take both to 2.5XX++ COAL. No flies on a 75 ELDM.

I PREACH a 700 based 7" RPM Vanilla 223 with 88's daily to pards,but everyone wants to get "tricky" or "fancy". I get it,because I have multiple rifles in all of 'em. Long story short,proficiency can't be purchased and a guy has gotta shoot. Had a pard over yesterday evening,who's missed more big shit,than most folks will ever see and I gave him the 7" vanilla 223 88 Talk for the umpteenth time. To no avail. He was trying to fuck me outta Seven DEADLY Sins and I just laughed.

A .473" Donor for a Little Guy would be 6BR and 7". A .378" would be a Vanilla 223 7".

Need to make a modest jaunt this morning and sniff around,while shooting come-ups on a few New Toys,then make it home before Post Office closes. With a shred of Weather luck,there will be a Mini Howie 7" RPM Bart' 22PPC AFI Carbon Queen lying in wait. 88/90's at 2800fps from a 19" and sub 4.5lbs bare rifle,with 4rd flush BDL bottom metal.

I can see it upsetting The Herd........................(grin)

havent totally ruled out tikka ctr mags but most likely stick with poly mdt's for play and am opened up in the front for reals


got a pile of 75's and shitty lever.

wouldn't suck to run 6br lite with 88's

but comparing ideal 75's freebore and 88's looks like a guy should pick one and run it.. 160 i'm out of the neck or jumping a mile with 75's.. not to mention COAL issues with 88's run that far out

.072 and 88's isn't ideal

right now leaning .09 freebore and 253 neck

thoughts?

.253" is snuggerish and mine tend to not be pristine,so I'd want a few thousandths more clearance. Lapooey Virgins are knocking on that door.

Numbers can get jumbled and transposed. Simply seat an 88 where/how you wish and KNOW that a 75 will feed happily,from the same trough. Throat to kiss said Dummy and you are golden.

Don't get greedy in any direction and simply take the EASY win...................

Oh man ND,

You're making me want to spend money.
Haven't felt the need to tinker with my 243 Montana despite it's horrible twist.

Maybe if I rebariled it and made it less gay blue purple looking I would actually want to shoot it

Who do y'all turn to for Montana spouts? Ideally one that would have a bit of extra contour no more than an inch or so from port so I could get enough beef to thread 5/8x24.

The Kali Kid LOVES to recontour,as per whim. Simply pick a tube that Greg has on the shelf,have him Mail it directly to Kalifornia and shout on the horn to relate recontour preferences.

Hard to motherfuck a 6BR,for any application...thoughmy next Montucky will be a 7" RPM 224 Speedmire.............

pacnor did this one

630$ all up for my cheapass seems like good value.

running cwh's 6x42 fx3 with m1 ele turret.

debating on running 90gr eld-x to gain a bit more point and shoot range over 105's rainbow.

i'd probably 87gr vmax with imr4198 a 243 before i did another 6br but you don't know what ya don't know until ya try. then again i got that angle covered already

pretty unimpressed with kimbers as a whole but a guy needs at least one wood stalking flyweight in the quiver even if it never gets used.

me and dan were yarning the other day but i just don't shoot these things well enough to even think of them as next zip code rigs

kudo's to those that do but i shoot bug holes with the krg bravo and a #3 contour. outside of offhand shit i get problems with these welterweights

Was gunning THE Carbon Queen yesterday at 1000yds + and it didn't give up anything to a 15lb KRG Bravo 223AI,wearing a DMR II.

'Queen from a ruck and a fist for rear "bag" and Bravo with Swivel 9-13" Harris(short as it would go). More mass is easier to hold MPAJ,but it ain't like Flyweights/Lightweights cain't play.

I'm happy to grant anyone,with any thing,first poke and will bat clean up with a Montucky 6BR. It ain't even "fair"..................(grin)

Shooting lightweights is a skill I don't possess.
But I need more excuses to practice anyhow

For me,it's ALL about the trigger. Mechanically,Montucky triggers are killer,due their shape/size/interface and mechanical geometry. THE Carbon Queen's 2-stage ain't horrid and came down rather nicely.

I shoot ALOTTA Double-Ounce Shilen's and fucking absolutely love them...................
