Hi L - The best thing is what we use at my range - Princess has magnetic floor sweepers - there are some on Clearance ca $17 if you live near a store. Otherwise there is one for $29.99 -

It's very convenient if picking up 100+ cases. BTW - my FT only tosses them about 10 feet, but zero to 45-deg right. TWO things you can do to reduce the throw if yours goes flying -
1) easy fix - drill some additional holes in the gas tube to reduce throw - only do a couple of 1/8" holes about 1" from the gas-port end. If this is not enough, drill a couple more, but Don't go nutz, you can't put it back.
2) - more work - 'square' the rear of the ejection port to direct the cases back towards a 3-o'clock direction. Lots of work with a dremel, but if you have an angle grinder and a 'fine touch' it's easier.
PS - Here's a 'zeroing Target' also.
