Description
If you shoot a straight-wall rifle in .350 Legend or .450 Bushmaster, this Birchwood Casey kit takes the guesswork out of picking the right tools. Everything inside is sized for those two calibers, so you're not hunting through a general-purpose box trying to figure out which brush fits your bore. The heart of the kit is a free-spinning, locking handle paired with a 5-piece brass cleaning rod, which lets you run smooth, controlled strokes without the rod wanting to spin in your hand.
What Comes With the .350 Legend / .450 Bushmaster Kit
Birchwood Casey stocked this one to handle a full cleaning start to finish. You get bore brushes and mop brushes in .357 and .450 to cover both calibers, brass jags, plastic slotted tips for running patches, and a dual-ended nylon brush with threaded ends for scrubbing carbon off the action and other tight spots. There's also a pick for digging out stubborn fouling and a stack of 3 x 3 cotton patches to finish the job.
Staying Organized During Cleanup
The custom case is more useful than most kits give you credit for. The lid doubles as a parts tray so your small pieces don't roll off the bench, and the built-in kickstand props everything up for easy access while you work. A self-adhesive magnetic strip is tucked in too, which is a small touch that pays off when you're wrangling tiny threaded tips and don't want to lose one to the garage floor.
Straight-wall calibers like these tend to run hotter on fouling than you'd expect, so having a dedicated setup makes regular maintenance quick instead of a chore. Keep the bore clean, keep the action carbon-free, and your rifle will thank you at the range and in the deer stand. It's a practical, no-nonsense kit that earns its spot in the cabinet.

Frequently Asked Questions
Does this kit really work for both .350 Legend and .450 Bushmaster?
Yes, that's the whole point of it. The kit includes bore and mop brushes in both .357 and .450, so the .357 tooling covers your .350 Legend and the .450 tooling handles your .450 Bushmaster. You get everything for both calibers in one case.
What kind of cleaning rod comes in the Birchwood Casey kit?
It's a 5-piece brass rod that threads together and pairs with a free-spinning, locking handle. Brass is softer than your bore's steel, so it won't scratch the rifling, and the free-spinning design lets the rod follow the twist of the barrel for a smoother stroke.
Do I need to buy solvent or oil separately?
Yes. This kit is focused on the mechanical tools, so it covers rods, brushes, jags, mops, and patches but does not include bore solvent or gun oil. Grab a bottle of your preferred cleaner and lubricant to round out the setup.
Is the case worth keeping around or just packaging?
It's built to reuse. The lid doubles as a parts tray, there's a kickstand so it stands up on the bench, and a self-adhesive magnetic strip helps corral small threaded tips. It keeps the whole kit together so you're not digging for pieces next time.
