Joe,
I have an old Focal spotting scope that I use for indoor archery, it worked exceptionally well there, but the OP says he's using it for BPCR Silly's, for the 200 yard ram in 22 it's right at the edge if you have good eyes, not so good for old eyes. If he's shooting the 500m ram with CF - the 20x Focal is tough even with good, young eyes.
If he decides that he wants to shoot BPTR and poke holes in paper, by the best glass you can get, you'll never regret it.

It's not the best choice, as with anything, more $$ and good research can get you better results. From the old Focal, I graduated to a 20-60x by 80mm Leupold that got me by for several years, they run in the $350 - $500 range -similar to this one on eBay - item # 324678946253
I moved on to a Vortex because it had an MOA grid in it, the glass is slightly better than my Leupold, but for seeing when it really matters there are better.
If you stay in the game very long you will probably move on to the better ones yet. Don't ask how I know... Low light or difficult conditions really change the game.
Aging isn't kind to one's vision and good glass like Leica and Swarovski come with a substantial price tag. Cost makes one pucker and clench but the view is awesome and it keeps old farts in the game.
Just my 2¢
