With a .378" Donor in the mitts,223AI all the way. I have (13) of 'em and ain't done.(grin) Tough to beat a 75 kissing in the neighborhood of 2.450" COAL,in an 8" or greater RPM. 88's don't suck there and their .545BC is for fhuqking real.

In .473",22-250 SALAMI would be my LAST choice. Don't have any in greater than 7" RPM(Mike Rock). 700 based,A5,lotsa inclination,lotsa erector travel and it's a hammer with 75 ELD's,but I'd wayyyyyyyyy rather shoot 223AI. While '250 SALAMI capacity is greater than 223AI,the velocity difference ain't enough to walk away from 223 logistics,mag capacities and the like.

Bottom left. 270 with 105's to it's right(8" Brux),then Six Twat-Six with 105's(8" Brux),243AI with 105's(8" PN),HEAVY 270 with 105's(7" Bart'),LFB 6-284 with 105's(8" Brux),6BR(no-turn) with 105's (8" Bart'),7-08 OEM spout,1717D HB OEM spout,77/22 Hummer with LW Clark spout...top Krunchenticker 243Win SALAMI 7" 5R,Mike Rock 7" 223AI lastly.

I fhuqking HATE Krieger so had Greg send one to Shaen,for a 22BR build,but the most RPM on the shelf was 8". No-turn,.090" freebore,lotsa Primal/AICS mags in hand and DBM/Stocks for same,but just might go BDL in Marty steel M4 bottom. 20.3" because I like round numbers and a 75 ELD focus,because I don't think 8" RPM at that velocity threshold,will make me giddy. 10x MQ a given,still factoring the inclination route with a fresh shipment of Glen rings and Reupold PRW 2's arriving this afternoon. I like Marty's 45MOA rails. Decisions,decisions.

I'd go 22-250AI over SALAMI and have many times. 7" fhuqking Krieger.

Nice to gun Alpha 22 Kreedmire Virgins in same,as you are all but there. The forming transition from pressing the trigger upon same,being rather modest. Hint.

Better yet,is to simply cut to the fhuqking chase and go 22 Speedmire. I'd NEVER build another '250 SALAMI or Aye-Eye. 88's at 3200fps+,assuredly do not suck and 8" will happily do it there,in all atmospheres(was doing more of same earlier today). That BC,at that speed,with 108 MOA remaining on a 10x MO/MO do not suck.

I've (3) Seex Kreedmires,though none faster than 7" nor slower than 8". It's a better mechanical design,than the 243 or 243AI and I've lots of them all. Hint.

The Deuce,Deuce Mag and 22-204 are all Dog Schit,compared to the 223/223AI,in logistics alone. Hint.

The 224Wby an even bigger piece of schit yet and yes...I fhuqking suffer one in a fhuqking Varmintmaster too. Should spin a 21" contour duped 7" no-turn 22BR spout on it and live a little...but it's like Peterson brass,in that it's a GOOD fhuqking laugh,when compared to everything else in the larder. Hint. Laffin'.

The Speedmire/88 melding,is a BAD Bitch for a Niche Tool.

High RPM 223/223AI all the way,for Utility.

You've been led to water.

Thank me later.

Just sayin'.
