For the average deer hunter's 30-30 the BoreSnake is an acceptable cleaning method, combined with a trip to the gunsmith occassionally to strip clean the weapon. If you can take down the 94 yourself a stainless steel 1 piece rod is the way to go. It should be smooth with no sharp edges and use the brass jag tips and all brass brushes. The carbon fiber rods are also acceptable, although I've little experience with them.. Avoid cleaning with ANY rod from the muzzle. The BoreSnake can be fed in and does an OK job on powder fouling. Jacket metal fouling is more difficult. The aluminum rods, brass rods and plastic coated rods are inferior. They can. Damage the bore not by scratching but by 'lapping'. Lapping is a process where a soft material and a hard material are rubbed together with an abrasive between. The barrel steel is the hard material, the aluminum/brass/plastic rod is the soft. The softer material absorbs or embeds the avrasive and the harder material is worn away. The abrasive is supplied by the carbon fouling and partially burned powder granuals. A bore guide is an excellant idea. Stainless steel is too hard to readily embed and strong enough to avoid bending and flexing against the inside of the bore as pressure is applied.
