Full sizing once fired 270 brass

[eurobolt]

Hi Guys,
is there anyone out there that can give me some answers on this topic,I have a Browning Eurobolt 270 which I have re barreled with a Border cut Barrel,1/9 twist
I am aware that the chamber tolerances will be less than a factory built rifle,however here is the rub,when reloading with brand new brass,fired ,chamber formed,I reload same and neck sized,everything is fine,the formed case gives me 2.043.5th Head Space,shoots and ejects ok, I recently was given once fired Norma Brass fired in a Tika 270,I full sized and measured to Datum line took a random selection of this Brass,they were within the recommended tolerances , however I always cycle the sized brass thro the chamber and found that 30+ shells would not cycle, in fact I could not throw the bolt,even with slight pressure of the bolt jammed the shells,some had resistance ,I dumped them too,I checked them for head space they were a wee bit over so I bumped a couple back ,this made no difference.Have checked O.A.L. of brass Ok. Best to stick with new Brass. Any Ideas,would be grateful for you input. Morse

The internal diameter of your full length die is larger than your chamber diameter and it is not sizing your case small enough.

You made them shorter and they didn't fit, so the cases must be fatter than your chamber.

I'm not sure if a small base die would put your fat cases on a diet and slim them down.

you can try small base sizing die. You may have to get a custom die or have the chamber opened up with a larger reamer.

you can try small base sizing die.

Before you buy one (if you don't have one), measure the base of the Norma brass and see if the base is larger (by say .001 - 002) than your new brass and then the small base die is likely your answer. Otherwise you are sending money on something that isn't the fix. But oft time, Norma brass is thicker than others.

Thanks Guys, for your input and advise,I use a mixture of new Norma Brass & New Winchester brass and have never had a jam with them,this is the first time I had an offer of once fired Brass,I had this barrel made for a special build and paid £700 ($1000 + Dollars) so it would defeat the purpose of opening the chamber for a few rogue shells tho I see what you are suggesting Alex , my conclusion is If it works don't fix it. Your comments are very much appreciated Thanks !!! Morse

With gun laws so strict in Europe as a rule,I cant believe they allow silencers.The USA is so stupid they make it impossible in some states to even own one.It is a 20 year prison sentence for possesion.We could use them and the rich and mighty wouldn't get the panties in a bunch.I would love to use one to get away from using hearing protection while hunting. Didn't mean to hijack your thread but couldn't resist after seeing the pictures of that fine rifle you own.

Thank you for your comment jonbearman, I have to apply to the Police to own a Sound Moderator and have good reason to possess it,I shoot on two small farms near houses and not to disturb people at night when out lamping for foxes also health & safety reasons, you are correct there are benefits in not having to wear ear defenders
all my rifles .22/.223/270 are all moderated, I am interested in all comments regarding reloading and gunsmithing and your Laws regarding all aspects of Gun ownership as our laws are very strict and it is good to discuss and debate Pros & Cons,
however this may be another thread.Cheers again for all suggestions and comments
