mouth must be deburred.
3. Wrong bullet diameter for caliber.
D. Bullet loose in brass.

Maintenance
Lubrication: Operating circumstances will
dictate the frequency of required lubrica-
tion. It is highly recommended that the XL
650 be cleaned and lubed after every 3000
rounds of operation. Use oil or wheel bear-
ing grease. Never use penetrating lubri-
cants, aerosol sprays, or solvent type lubes,
such as WD-40 or Break Free.
Lubrication Points:
Shellplate bolt – Grease.
Main Shaft Lubrication –
Use only 30 wt. motor oil. Once again, do
not use penetrating lubricants, aerosol
sprays, or solvent type lubricants.
