CLEAN AFTER BLANKS

Firing live ammo in your small-arm right after firing blanks is strictly verboten ... unless you clean your piece first. For one thing, the carbon from the blanks builds up in the barrel, leaving you wide open for a rupture. For an-

other, the blanks cause a ring of carbon and stuff to form inside the chamber,

keeping the live rounds from seating just right. This not only has an unhappy effect on your disposition, but it plays hob with your headspace. So clean your barrel immediately after firing blanks. You'll have much more fun on the wet runs when you've gOt a good clean piece.

MUD IN YOUR EYE?

Some of the outside seals on M41Al tank periscopes aren't as watertight as they could be. Particularly on tanks with Ordnance serial numbers below 3211. A new type sealer was developed with that number. If you're gctcing mud and moisture in your e yepiece , here's what you can do:

T69 BOGIE BLOOPER

Dear Half-Mast, Before MWO Ord D48·W3 was ap· plied to our T69 gun mount (75-mm gun) we had trouble with the wedge handle hitting the receptacle box otl the rear bogie. The MWO took care 0/ that by moving the box, but now the box gets in the way when we put the mount into firing position. What gives.' Did so'm ebody foul up here? Sgl J. S. B.

Dear Sgt J. S. B.• Somebody put that bracket back too high or too low on the bogie axle, and not according to figure 3 of the MWO. And believe me, that's an easy mistake to make. About the only time the axle is in the right position for the MWO is when the bogie is in the traveling posi. tion. (The MWO told you about that.)

]f the work was done while the bogie was detached, the bracket was probably put on wrong. It may have looked right then, but when the bogie was attached for traveling. the axle turned and threw your bracket off the beam. Yell for Ordnance and have 'em put it on right-while the mount's ready
