rem model 8 primers backing out
i have a remington model 8 in 25 remington.finally got a chance to reload some new made brass from buffalo arms.useing starting load of 18 grains of h-4198 with 117 grain round nose bullet.hasnt been shot in 40 to 50 years.shots fine and accurate but will not eject shell and primers are pushed out.i have looked on the forum with other guns with same problem and there seems to be a list of reasons from too light a load ,bad headspace to brass problems.if any one has any suggestion on how to cure this feel free to answer.

Considering the 40-50 years of "sitting", did you do a detail clean/lube of the mechanisum?
Assuming the rifle is properly cleaned and lubed, the combo your mentioning (ejection and primer protursion), sounds like a low pressure situation to me.
I don't have loading specs in front of me, but IIRC 25-35 Win data is the same as the 25Rem, and your 18gr charge of 4198 also sounds a little light and slow.0 -
Hello are you SURE the chamber is really really CLEAN sounds like a light load and dirty chamber is not letting the shell move back to the bolt face and also not allowing the action to work properly to function and eject the shell.
All the other post have a valid point about head-space but I still say LOW pressure will show up as head space problems even in guns that have correct head space on most guns this can be proven by just firing a primed case NO POWDER OR BULLET the primer will back out the pocket and a dirty/rusted chamber will really show this up.0 -
Also, shoulders have been pushed back and headspace is excessive.
After taking loaded ammo apart, expand the necks using a 30 caliber expander button then neck down using the 25 Cal sizer, leaving the expanded neck unsized to the same the dimension primers have backed out.
Alternatively, expand as above and neck down to 25 cal progressively
until the bolt will close and lock. Reload and fire using PUBLISHED data.
Reset your F.L. die so it will not move shoulder back and test chambering before loading the brass. If it's too tight, bump the neck slightly and test for chambering.0 -
Primers cannot (should not) pop out unless headspace is too much for this brass. If you reload the brass a second time, you should not have primers coming out. The cases should be fireformed after the first firing in this chamber. The primer pops out upon the first firing because the chamber shoulder (where this case headspaces) is longer than your new brass. The case is forced forward by the firing pin. Since there is a gap at the bolt face, the chamber pressure forces the primer backwards. This also releases the case head from the extractor. Hope this helps. Bob 0 -
