mid-range calibers for my break-action single shot

I had a 14 inch 6TCU that was scary accurate topped with 12x Leupold. W748 with 60 Sierra HP. Took a real good rifle to out shoot it. Consistant quarter inch groups. Best victim was a 500 yd big Pa gobbles. Yes, a very unlucky bird. So, try a 6 TCU, Lots of fun.

 

the 6x45 is just a 223 necked to 6. dies are common brass is plentiful. The tcu has a bit more gooder, but only a bit.

 

As above, 6MM version. Best selection of bullets out there.

 

FYI: All TCU chamberings sport an Ackley shoulder (40°)

 

Looks like your 250 Savage is Ackley Improved also?
Shoulder in pic looks sharper than my standard 250 Savage.

 

It is not. I apologize for the angle of photo but I have to keep my pressures lower than factory specs because of the contender's tolerance.
I only load to around 39,000 PSI because of this but it is a real performer even at that velocity.
I appreciate a 40° should and enjoy it on all TCU chambers, 223 AI & 30-30 AI, and even have a 358x444 Imp.
