Next caliber quandary??
Gday all,
Hope this thread finds you all safe and well. In a land down under we have faired well on the Covid front - but the economic woes may still be ahead. Help we with a caliber decision please. Currently have a Tikka M55 in 222, a Browning A Bolt in 22 Hornet, a Brno model 2 in 22 lr and just about to take possession of another Tikka M55 in 17 Rem. The 17 Rem was acquired on the basis of turning it into a 6x45 or 6TCU for goats and pigs within sensible ranges (150 max) and having fun plinking rabbits etc as a field carry rifle. Question - would I just be better off putting on a new barrel in 223 with a 9 or 8 twist and using 60-70 grains in the 223 or will the 6mm genuinely give more ability to handle pigs etc? The task of forming brass and reloading for a wildcat is not too daunting - but is it really worth the effort if there is no measurable gain? For the record - I do intend adding a 270/308 or similar at some stage as a dedicated pig rifle. I’m terrible at making these decisions - it’s really not knowing if 6 mm will provide any real benefit. Cheers, jawry |

Personally I would go with the 223 and the 1/8 twist. It would handle the pigs just fine, and to my way of thinking, a better all around cartridge for your needs. Bill K

I thinks the 6X45 would make a dandy round, but if 150yds is all your looking at either will do.

Thanks Gentlemen,
Does one cartridge provide any real world advantage that would be noticeable e.g. more ft/lbs of energy, more penetration with the practicable bullet weights? For the 223 for ‘hunting’ type bullets that appears to be around 50-70 grains and 70-85 in the 6mm. By virtue of physics - it appears that for the same projectile weight - slightly more velocity is available in the 6mm. This is at the cost of a slight deficit in BC for the 6 - though I doubt either we be of much significance for the ranges involved. This will be a walk about general purpose rifle with ranges out to 150 (very occasionally a tad more) I love the idea of a mild 6 - but not if there is no practical real world advantage. Thanks for listening to my ramblings. |

Ok
Not sure if you like Howa rifles but the mini is chambered in 6.5 Grendel and they are lightweight and accurate not to mention well priced
Also it well still fill a gap when you buy a 270\308 class rifle Have been thinking about one of these myself I think they would have plenty of power for mid range hunting |

having owned several 6x45 as well as my friends owning a couple, the 6x45 just seems to hit harder. velocity in the low to mid 2900 is where mine seem to shoot best with 80-85 gr bullets. I have shot deer (whitetails) out to 2900 yards with great results.
I think the heavies true hunting bullet for the 223 is the 65 gr sierra game king with similar velocities. remember on a pig you have to pernitrate the gristle plate to get to the vitals. I personally would go with the heaviest hunting bullet available. the heavy .223 bullets are designed for target shooting. keep in mind 6mm bullets are designed for the bigger cartridges such as the 243 velocities and the varmint bullets designed for the 243 act like big game bullets at 6x45 velocities.

6-223/6x45/6TCU or even the 6x47/6-204 perform over the top of most expectations. Hogs, I would not skimp on bullets. I can put you in contact with a fellow in Texas that has tested a lot of 6mm,6.5 and 7mm bullets in milder cartridges.
Imho it was easier to get the little 6mm shooting than the 223. Lots of good varmint bullets along with good edible game bullets. 2900 yards, over a mile and a half, you may have some numbers mixed up. Last edited by JSH; 05-04-2020 at 04:47 PM. |

jawry,
Take a look at the Sharps Rifle Company website and consider the 25-45 Sharps. This (Mine) out performs the 6x45 by quite a bit, with velocities beyond 3000fps with a 90 grain hunting bullet. (Over 1700 ft lbs) Mine worked very good on our Fallow deer. My longest one, 184 yds lasered. H& lung shot, no run, deer did a back flip, kicked a bit and died. Ken. PS. No need to drive them as fast as i did, sometimes those bullets work better at slightly lower velocities. I needed to get mine above 3000 fpsto comply with our Deer shooting laws.

Just wondering what load was giving you 3000 fps with a 90 gr. bullet. Quickload suggests that such loads would have some pretty stiff pressures.
Cartridge : .25-45 Sharps Bullet : .257, 85, Nosler BalTip 43004 Useable Case Capaci: 24.558 grain H2O = 1.595 cm³ Cartridge O.A.L. L6: 2.260 inch = 57.40 mm Barrel Length : 18.0 inch = 457.2 mm Predicted Data for Indicated Charges of the Following Powders. Matching Maximum Pressure: 59250 psi, or 408 MPa or a maximum loading ratio or filling of 105 % These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window. C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand that all of the listed powders can be unsuitable for the given combination of cartridge, bullet and gun.

Johnly,
I asked 3 different guys with QL and each came back with different figures from the same information I gave them. I don’t use QL but rely on observational data. Still, (fingers crossed ) got 4 fingers, 2 thumbs and 2 eyes. Not gonna tell anyone my load data. Just work up SLOWLY, as you’ve been advised many times. Most people that publish load data work on the conservative side. Regards,Ken.
