Based upon the earlier 'slug the bore' discussion and further discussion with the lady of this household I have permission to proceed.

I have an Argentine with the rotary extractor in 43 Spanish.

I want to build a bench gun and I'm thinking that I'd like to go with a  25-35 Ackley Improved, set trigger, and optics (probably blocks for my STS but also a Weaver base a for regular scope).  I'd like to have a pistol grip instead of a straight grip.  The current wood will have to go.  I also thinking about having 'Colt Engraver' doing a little special scratching on this one.

Now, two concerns.  I don't know any Roller experts, and need a recommendation (one in Virginia would be nice).  The last concern is what am I missing?   

Additional ideas or suggestions would be welcome.

Thanks

My opinion is that the 25-35 AI is too hot a round for a blackpowder rolling block action, which yours is.  If it was a 1902 smokeless model, it would probably work, but it's maximum even for that action.

I'd suggest talking to Glen Fewless (HST) on here about working on your rolling block, he knows and likes them.

Dave & Joe, thanks for the opinions and suggestions.  I appreciate them and know that you are right on target.

I had spoken with Ken a few nights ago and then followed up with HST minutes later.  What a bunch of great guys!   Glen indicated that the Roller was not capable of achieving the performance that would satisfy me on this project.  So I'm thinking of selling it to help finance this project.  At Glens suggestion, I'm now  looking for a Browning 78 for as the basis of building that bench gun.
