Because it's a pain in the butt, that's why! But I had to do it today, because I was having problems (Federal blue box Champion ammo didn't help either).
1. You have to disassemble the action from the stock.
2. It takes tools to strip:
Barrel vise jaws
Shop vise
Pin punch
Hammer
Screwdriver
2. Then you have to take out the 2 trigger assembly pins, usually not hard.
3. Then you have to pound out the big third pin in the back of the receiver. Much tougher.
4. Then you have to pull the bolt back with one hand, and with the other, try -- try -- to lift up the bolt, against the pressure of the action spring rod. At this point I have the barrel chucked up in barrel vise jaws, in a shop vise on the workbench.
5. Having accomplished all this, you now can't clean the bore (or, more importantly, scrub the chamber) from the breech end.
6. Reassembly is even tougher. With the barrel again chucked into the vise, you have to place the spring guide rod just so, and hold it back with a screwdriver, while trying to drop the bolt down in the right spot.
7. Then pound the big pin back into place.
8. And what's your scope saying when all this pounding and gyrating are going on?
9. Then put the 2 trigger pins in and reassemble the trigger group.
10. Hold the safety just right, in the middle, against spring tension (no detent for this position) and put the action back in the stock.
11. More screws to tighten to hold the action in the stock.
What a pain in the arse.
I used to generously lubricate the bolt and the action spring rod, like you're supposed to do with semi-auto firearms. No more. The action collects a lot of crud, and excess lube just makes a nasty paste.
Now, how is anybody supposed to accomplish this in the field?
