Yup, the missing link is here.. the .012 incremental caliber between .284 and .308
.296 So far there's are 2 bbl manufacturers to be making bbls, McGowan and Broughton
by contract of Macs Gunworks in WY
I know they are testing them with a necked up SAUM cartridge.
Some will say waste of money, blah, blah, blah, why not just a .30 yap, yap, yap,
I say awh go sit on the porch.
The heaviest bullet so far is 198gr& has a 15cal ogive a 9 degree x .220 boat tail (cup and core)
and is 1.515 in length with a .060 meplat, anyone care to guess the BC? please...
smells like a good thing to do to a shot out 7mm when you don't really want to go 30... run a button through her, adjust the chamber slightly for new neck dimension, and neck up your brass for the new pills..... I'd guess the pill you mentioned to be in the .600 range for bc. but I'm in the if it's pointy it flies crowd so I really am not the perfect person to answer this.....
hey guys, we have 24 cal., 25 cal, 26 cal, 27 cal, 28 cal, and now 29 CALIBER. Im trying the ultra short action and calling it the 290 USA. Running 198 grainers at 2900 FPS. It shoots bug holes at 100 yards and 4" groups at a grand. I figure the BC on the 198s set .660 or better. i've fired nearly 800 rounds since October. Since its so fun to shoot, this baby slaps steel and probably the same on big game I can't wait to try it. matrix Ballistics for bullets, macs gunworks for rifles and barrels.
ps macs gunworks builds a precision action that fit these short mag cartridges oh ya!
trying it on 7 mag case next, calling it the 290 mag.
