I found a soft red plastic slug about 1" in diameter, maybe 3" long (wish I knew exactly what it was made of). I bored a hole just slightly smaller than the roller diameter and deep enough to stack about 3 rollers. Fill the hole with grease and work the roller into the hole and then push. It does a great job of packing the roller.
Not yet. I suspect that 7.62 will take longer, but ordered two from Brownells. They are enroute now....getting them to my mailbox will depend on the posties as they sent it via the mail rather than courier.
I will post as soon as I get.

interesting thread.
i've seen the odd norc where the roller has come off due to a crappy or broken retaining clip. I would venture to guess a heat treatment issue as well with the roller itself if it just blew apart.
pesky little buggers to get back on hehehe , have fun with that one
a 45 case 1/2 full of melted wax or a cut down .308 case works as an excellent roller greasing tool, allowing you to purge the old grease out of the roller, replacing it with new..... something not fully accomplished with the finger squishing method...... or buy the tool from brownells for 8.00

Update
I finally got some replacement rollers. 7.62 (I think) has yet to mail them to me, but got a set from Brownells.
Anyways, I believe the failure of the roller was caused by two things. The point of failure was situated inside the roller (retaining ring) groove. Recalling my metallurgy class (when I wasn't asleep), the material looked brittle as the failure point was about 2 mm in width, not pointed as an impact or stress point failure. The groove appears to be a little deeper in the Brownells roller.
The second issue, which could have assisted the cause was the retaining ring. The 7.62 ring was about .001" larger in diameter then the Brownells. The old roller did rotate with greasing, but I recall not quite as freely as the Norky or the Brownells roller.
When the monsoon's stop, I want to shoot it again and test it on the range.
