remington 552
got this 552 in my shop. customer says it is misfireing.
load it up and yep, snaps 7 out of 15 times. check cases, very light dimple from fireing pin. tear down and clean, replace fireing pin. same problem.tear down again looking for anything. no burrs at chamber mouth, polished chamber. same problem. trigger group looks fine. any ideas , something i am overlooking?

Hey guys, I am having some problems with a Remington 552 speedmaster. I think it is a feed ramp problem. Any suggestions on fixing it. Thanks for the help 0 -
Hammer spring (#43)? The case head is supported under the the firing pin, bubba wrongly sometimes removes bbl metal that was peaned out from excessive dry firing.

#1, Try a number of different type/brands of ammo. I have worked on .22's in the past that were very sensitive to this. Also a tight minimum spec chamber will foul very easily with certain types of economy ammo, causing FTF's.
#2, I'm not familiar with the 552, but certain firearms have a spring on the front part of their inertia type firing pins. If this spring is to strong when using ammo with insensitive primers, FTF's might occur. You might very carefully as long as you have a replacement spring, cut a turn or 2 off the original spring. On a trial and error basis to see if reliability improves.
EDIT #1, Perry Shooter has made a valid point. If this is the model with the floating chamber? This is probably where your getting your problems. There will be FTF's if the chamber has been fouled and doesn't bottom out properly on the breech end of the barrel. Go in with solvent and high pressure air to try to get the chamber clean, so that it can move freely.0 -
ok guys, i am at wits end here. stretched hammer spring 1/4".
i have tried different ammo... some will not fire at all, others 50 % of the time. it disturbs me when i can't figure something out.
i see no binding what so ever.[?]0 -
Look at GUN PARTS INC parts break down . Is the 552 like the old 550 that will shoot Shorts, Longs, and LR.[?]Does it have floating chamber of sorts. Also could this be a PRESS fit barrel and it has pushed forward in the receiver or am I thinking of Problems on Winchester model 190 /nylon 66 Remington. 0 -
karl, i have checked everything i can think of.it does fire some brands more often than others, but, that does not make it right. the barrel is not pressed in and no floating chamber.it has to be something with how the bolt is fitting in the barrel??? if i ever get it figured out, i'll post the solution. thanks man for the input.quote:Originally posted by perry shooter

"... bubba wrongly sometimes removes bbl metal that was peaned out from excessive dry firing."
The firing pin on modern rimfires, including the Model 552, cannot contact the chamber when fired on an empty chamber. Since rimfires seldom lock open after the magazine is empty, the shooter usually learns the magazine is empty when the hammer falls on an empty chamber. If the firing pin could contact the chamber edge, all of those rimfire firearms would all have peened chambers, and they do not.
The M552 does NOT have an inertia firing pin. The M552 does NOT have a "floating chamber" like the M550. (The M552 has a rubber block to cushion the bolt at the rear of its travel when fired with long rifle cartridges.)
I would replace the main spring since stretching it may not remedy a weak main spring. You might also check the head space to be sure it is not excessive for some reason, which could account for light strike impressions.0 -
I'm with the Judge on this one, check the head space, I think that is where your problem is.

damn i hate to buy a headspace gauge when i have already lost money on this one with all the tear down put back together.. and so on. i think headspace just might be the problem since everything else checks out.thanks guys 0 -
It is only a 22. You can make due with a dummy round and shim stock to check out head space. You mention a shop so I am sure you have dummy rounds for messing with 22's so you, 1 do not shoot a hole in your foot, and 2 are not checking function with spent rounds that may have been blown out of shape.
Also guessing you do not have a Remington Service Manual. Can not remember if there is any service info in Brownell's Encyclopedia.
Will look out in the shop later in the week as I no longer have power or heat in it. The 552 should not be a hard gun to get to go bang every time.0
