Just wondering, I recently came into a 1975 BLR 308cal; looking like it is brand new. Shoots wonderful with factory ammo.
Reloading however it has rather expensive taste, in order to get the rounds
to eject properly.
Equipment used:
RCBS dies, full length resize.
Wilson Case gauge to measure head space
Each case trimmed to 2.010 exactly ( Mid point as I measured brand new core lokts)
Here is what I noticed:
1) Building a round starting at min load with Varget, occasionally get a round that does not eject. Does not matter ranging from mid to max load as recommended from Hogdon charts. However, if I trim down to 2.005 and use Varget trouble really begins ejecting leading to madness and lots of curse words.
2) Building a round with CFE223 at min load to max load 90% of all rounds stick when ejecting. Not so bad you need to pry it open but enough so you do not want to use this load.
I Double checked each round with Wilson Gauge before and also after the bullet was seated to ensure the round was not somehow bent.
I Double checked the crimp to ensure no jagged edges and properly trimmed.
Tried with and without a crimp BTW. Even use 0000 steel wool after the
trim and clean up to ensure no rough edges.
Same situation no matter what bullet weight, 150 hard ball or 125 sst.
One thing noted is CFE223 has a slower burn rate than Varget. Might the situation improve to factory ammo conditions if I even step further down or rather fast powder burn rate.
Browning no help.. obviously with reloads.
Also Ultra Max professional reloads eject like crap too.
So cases trimmed to 2.010 using Varget works 95% of the time like factory ammo.
One thing I noticed is when using a dummy round and loose bullet to measure the breech, backing the bullet 5 thousands off the start of the rifing places the bullet too long to fit into the mag.
Any ideas what is going on here? I would like to understand what is going on here. Also, would like to build a round that I can say 99.9% will eject correctly.
