..........as a matter of fact I do have a BLR for sale in this chambering.

And it is a Belgian model, quite a nice rifle.
I would suggest to secondgen that you should try to handle a bunch of lever guns if you have not done so. They are not all created equal: even those guys with poor taste that think there are prettier guns than BLRs are only talking about appearance.

Stock designs are radically different between the makers (and models) of lever guns. For example, I cannot get a sight picture on a Marlin 336 unless I lift my cheek off the stock. If you lift your cheek off the stock, two fairly predictable things occur:
1. The stock comes up to smack you.
2. Accuracy goes south.
From personal experience, you will not see many 88s go by in .243, and if you do see one chances are it will be fairly pricey. Lately there have not been a lot of 99s go by in this chambering either. You do see the odd BLR for sale in .243, and of course Browning still makes them if you are after a new gun.
But anyways, I would encourage you to test-drive a few lever guns before you buy one. Good luck to you! But be forewarned that lever guns are dreadfully addictive!
