Will the model 63 fire even when the bolt is not fully closed. Being a blow back design there is no locking into battery as in most semi auto Winchester designs.
The 351 SLR will not fire if the breach block is not well forward in the closed position. Is the 63 different and I have a broken action?
It is a blowback action and uses the weight on the bolt and any additional weights riding with it to delay opening before pressure is safe. There’s no locking mechanism. Being a Rimfire it can’t fire the cartridge if it is not fully supported by the chamber face…thus closed. Have someone familiar with the 63 look at it.

I can open the action enough to see the breach block is out of battery, pull the trigger and the hammer will fall. I have two model 63’s and both will do it. The Winchester 07 in 351 caliber will not fire when out of battery. Looking at parts break down, I see little to suggest that there is a means of preventing a round being fired if the breach block is out of battery.
Cleaning this gun very well is critical. A feeding problem can cause a round to not chamber correctly. Between being able to fire out of battery and the shear inertia of the heavy blow back action, can discharge a rim fire 22 round not properly fed into the chamber.
