I only have one rook rifle. It is a nice small Belgian Martini that was in 300 Rook. I say was because 60 years ago when I acquired it 300 Rook brass was not available but 32 Long Colt was close so I had it rechambered. The heeled bullets would chamber and shot fairly well but left a mess of lead in the throat. Then Buffalo Arms started making a beautiful little 300 bullet mould which creates bullets that match the bore and seat perfectly in the 32 Long Colt brass. The result is a cartridge which at first glance would pass for 300 Rook and shoots very accurately. Actually, the "rechamber" was just to increase the rim diameter .005 so the Colt case would seat. The Colt case is about .020 shorter than the Rook but it doesn't seem to harm the accuracy.
