270 win reloading - Savage Axis Rifle

[JimMac]

Brass - hornady , winchester , FC

bullets , SST 140g (#27352) and gameking 130g (1820)


all loads with the gameking bullet with hornady and FC brass chamberd fine

the SST bullets in the FC brass wont chamber , can get the bolt handle down
without alot of force.

the only SST that chamberd was in winchester brass.

9 of FC brass wouldnt chamber.


trim , 2.52 to 2.53 , OAL on SST 3.222 , OAL on gamkings 3.303


Any Ideas on the SST no chambering ?

All casings full length resized ?

If so, possibly the ogive on the SST is farther forward on the bullet than the Sierra and the bullet is contacting the lands..An easy check would be to seat the SSTs a little deeper in the case on one of the rounds that doesn't chamber well and see if that helps.

X2 what Pygmy said. Also, you can blacken with a sharpie the ogive of the bullet and the shoulder of the case and see where it is making contact. Most likely, you are not pushing the shoulder back far enough on the FC brass. Simple fix.

Providing that all cases were FL resized, it seems that seating depth is the most likely issue...You are already seating the SSTs to a shorter COL, but those plastic tips can make a big difference, as can basic bullet shape. Now if you are neck sizing, that's another variable to be considered. I full length resize all of my hunting loads.

Every time?

thanks for the replies guys , the gameking bullet longer and the ogive on it is like a fat hump

and with the SST there like a needle ,, its not the ogive or the sst tip ,,

 

found out FC brass is soft and my full length sizing die needed  a 1/2 more turn down

to set the case neck shoulder back some. FC brass chambers fine now in the rifle.

 

*The FC brass was range finds

The only brass that I do not FL resize is new, unfired casings..With them I run the die down  just far over the expander ball and then load 'em..

It seems you were incorrect.

[Pygmy]

Certainly not the FIRST time I've been incorrect... If  it interests you that much, I'll give you my ex wife's number and she can tell you about DOZENS of other times I was incorrect..
