I'm reloading some .270 ammo for a gun new to me.

After full length sizing the 30 or so 1x fired cases, I neglected to chamber an empty case in the rifle to make sure it chambered ok. Well, turns out after loading up my 30 or so test load cartridges, I didn't set the sizing die down far enough, and the rounds are hard to close the bolt on.........but it will close with some effort. Dummy me! No, it's not the bullet touching the lands....i blackened the bullet to test that and it's not touching anywhere. I FL resized another case, this time with the die set down 1/4 turn more, and the empty case chambers and bolt closes with normal effort. Cases were trimmed to correct length also.

Anyway, I don't want to pull the bullets and powder and resize the cases again if I don't have to. Are these test loads safe to fire?

Thanks for your thoughts.
 
As Ganderite stated lube the rear of your bolt lugs.

Proper Cleaning and Lubrication Ensures Bolt Reliability and Long Life

"BOLT Lubrication

Like any piece of machinery subjected to high pressure and cyclical movement, the bolt needs lubrication.
There are three main areas on a typical bolt that need lube: the locking lugs, the cocking cam, and the extraction cam.

1. The Rear Surface of the Locking Lugs

There are two lugs on most bolts, three or four lugs on some actions. Wipe these clean with a paper towel before re-applying the lube. Dab a little of the grease on the tip of the small screwdriver and spread it on the lugs. This should be a thin, even coat. Just thick enough to cover the metal but not globbed on. This picture shows the lugs wiped clean before lubing. A locking lug recess cleaning tool such as Sinclair Int’l offers is useful to ensure that any grit and bits of brass that collect in the receiver’s lug recesses get cleaned out."




And if you ever use the O-ring method of fire forming your .303 British cases in a Enfield rifle "MAKE SURE" you lube the locking lugs.
 
Thanks for the replies.

Yes, the .270 loads I have made are within currently published load specs.

I did not know to lube the rear of the bolt locking lugs. Now I do and will do so!
Thank you for your help.

Note, when closing the bolt if the back of the case starts to smoke and then the bolt handle breaks off the case is too long.

What I use on bolt lugs is GMC camshaft assembly lube. It stays in place, and it's anti-galling characteristics are it's reason for
existing. A little bottle of that will last you 20 lifetimes. A little dab applied with a toothpick is all you need. Ted Gaillard put me
onto it.
 
The cam assembly lube is great, due to it's extreme pressure qualities. [zinc compounds]
Another good lube for bolt lugs is Molybdenum disulphide grease. A bit dark ,
but very effective when pressures are high, or a wiping action is present.
