I just cleaned my 6x45 BHW barrel and tried to feed a few dummy rounds. I had to mortar the new bolt open.
I removed the o-ring from the extractor and lubed the bolt and it got better. I fed some 223 rounds and they ejected easily.
Then, the dummy 6x45 round fed and ejected easily. The 100 gr bullet got pushed into the case at some point.
The 55 gr Dogtown bullet remained OK in the case. I think the problems were caused by the bolt being new.
I will measure the case neck before firing any rounds and make sure it is a few thou below SAAMI minimum chamber neck dimension to give room for expansion.
I will load some tomorrow and maybe go to the range for testing.
I just measured a round with a bullet seated and it is .265".
SAAMI says the case neck of .269" and chamber of .270" so there should be .005" of room for neck expansion.
Case length 1.765" and SAAMI says 1.760 - .030 so I will have to trim to length.
SAAMI chamber says 1.7720" so it would probably work OK but I better trim anyway.
That is all for tonight.
