If you Boys want data for the 270AI I would be more than happy to share it with you. R22 is THE powder that shines above the rest.

260 ackley improved, 40 degree shoulder is my first wildcat. Still playing with it. Shot a buck last year with it. Having issues with reliable ignition. Wondering if I need to set bullets long to contact rifling, and hold the case tight in the chamber. The cartridge will go off on the second pull of the trigger, after its shoved forward in the chamber from the firing pin strike. Am I'm on the right track? This is on virgin brass still in 260 form, not fireformed.
I havent extended my OAL yet because its magazine fed, and I will have to single feed rounds to fireform. Meaning all bench shooting, and not during deer season. Gun holds 3/4" groups at 100 yds, with a pencil thin 1-8" shilen barrel. No complaints from me if I can get it to go bang every time. |

Seating a bullet into the rifling is one way but something is wrong and that should not be necessary. |

It was a custom barrel cut by a gunsmith for me, no previous chamber, fresh blank. Cases don't show excess pressure, primers look good. Still think excessive headspace? Would the gun group well with that type of problem?

There seems to be evidence of excess headspace. Could be the chamber, and could be the brass. Did you size the brass in preparation for loading it? If you ran it all the way or at least 'too far' into the full length sizeing die it's possible to have sized it too small in length. If you did size it, take an UNsized case if you still have one, and see how it fits in the chamber with no primer/powder/bullet. Should be at least 'some' feel of resistance when the bolt is almost closed/bolt handle turned down. Your ammo is not being held against the bolt's face when chambered from what you've described. IF the chamber was cut too deep then the barrel should be removed, face and shoulder of barrel cut back a predetermined amount [too provide correct headspace when refit back to action]. Try to find a box of FACTORY loaded ammo and see how it fits. Best way is too REMOVE THE FIRING PIN from the bolt so that no other interference is felt when chambering a round. Still, even though firing pin is out, treat the gun as if it COULD FIRE anytime inserting a live round. Last edited by Alan in GA; 06-20-2013 at 12:18 PM. |
