I have 3 blrs 81's and I really like them. But they have always seemed a little butt heavy or muzzle light. Is there any way to correct this problem Without a radical procedure like rebarreling ?

take off the buttplate and see if you can bore out the stock.

I know you can add lead to the forend.

With all due respect to Rob...be careful doing that. You can really weaken the side walls of your stock if your aren't careful and the amount of weight you will be able to remove is minimal at best.

Adding a bit of weight to the forend is far easier and safer, in my opinion.

If course you can add lead to the buttstock, too. And, if you are not hung up on looks...you could even experiment with a barrel "tuner" to both add muzzle weight and to tune your barrel to your load. (This last, incidentally, is goiing to see a LOT of use in benchrest competition in the next couple of seasons. IBS is just formulating rules to govern tuner use in their competitions, and some matches have already been won using them.)

Drilling out the stock and filling with that expandable foam stuff is probably the best bet.

Drilling out the butt and leaving it hollow has been done for 200 years and works just as well today. You can save serious wieght by doing this. Some guns, often English shotguns, are just a thin shell of outer wood, and they get used hard, many days a year. You can take out close to half a pound if you get extreme with it. Unless you are using the stock to drive T posts on a regular basis, then you should not have any problems with removing the wood.

BTW, if you want to add weight to the forend you can do it by bedding the aluminum rod with steelbed and free float the barrel at the same time. I've done it on both of my 81's.
