DP ishapore smle ?convert to .22rf ?

[ActionYobbo]

I have been thinking about doing the same thing but with a Mauser that will never fire 8X57 again
or any other large Mauser round for that matter.
The chamber and cannon (bore) too rusty.
I have an Austrian Voere .22 insert / conversion kit that will convert 7 and 8 mm Mauser to .22lr
but I would like to stop it flexing when I shoot.
Was thinking about grease on the insert and putting silicon sealant down the cannon (bore)
to take up the slack, and hope that the grease will help removal when I want to take the Voere unit out.
Or would it be best to epoxy in and never take it out.?
I know I am talking about a Mauser but it is the idea and the principles of this topic.

its up to you but I will be using a permanent method to set the liner in the barrel but you could use something like a thread lock compound that when heated will release so you can get the liner out but I think that if the gun is rusted out then a permanent conversion is better
