350 gr. Barnes TSX @ 2,400 fps / 5,115 ft-lbs
20-Round Box



Like the 375 Ruger, I was slow to warm up to the 416 Ruger as I’d been using the 416 Rigby and 416 Remington for decades and liked them, so I saw no need for the Ruger 416. However, this cartridge has some real advantages over the Rigby (which requires an enormous magnum action) and the Remington, which requires a magnum length action. The 416 Ruger was designed to be housed on a standard-length action, yet it holds only two grains less water (102-grs. versus 104-grs. depending on your make of brass) versus the 416 Remington and as such, can propel bullets of similar weights almost as fast.

This load is perfect for those who want the deepest possible penetration with an expanding bullet. I know of no premium/partition type of .416, 400-gr. bullet that will penetrate as deeply as this 400-gr. TSX bullet. When hunting Cape Buffalo with this bullet, I doubt you’ll need “solids” for follow-up shots. This 400-gr. copper alloy bullet is longer than a 500-gr., .416 bullet would be if it were made of typical lead alloy and a jacket.

You’ll note that my only test gun is a Ruger Guide Gun. This is a configuration of rifle I very much like. Its shortish 20-inch barrel is easy to handle and generates plenty of velocity with proper propellant choices. I heartily recommend this rifle with its controlled round feeding, three-position safety that locks the bolt, fast iron sights, stainless construction, weather impervious and LOP adjustable stock, muzzle brake, (if you like muzzle brakes) and barrel-mounted sling swivel attachment that saves your fingers under recoil. The scope mounts repeat to zero, so you can bum around the outdoors with the fast acquisition iron sights needed for close-quarters protection, but then attach the pre-zeroed scope and go hunting……all for around $1,000.00. It’s as if the folks at Ruger asked me to choose the design features for the Guide Gun series, but they did not.


 2,392 fps — 416 Ruger Guide Gun — 20-inch bbl

My particular 20-inch barreled, Ruger Guide Gun generates 2,392 fps with this load. I had hoped to engineer the 400-gr. bullet to reach 2,400 fps in this gun, so for all intents and purposes, we did it, in a 20-inch barrel. My experience with Ruger factory barrels is that they are neither fast nor slow relative to length, but are right in the middle of the road…..a 24-inch barrel would likely generate another 100+ fps. This is a great place to ask you to read my article on “Velocity Versus Barrel Length”.

For use on Cape Buffalo, I’d carry this load in the chamber, backed up by a magazine full of the same load. For use on large bears, I’d use our 350 gr. TSX load, although this load will work great and will penetrate deeply enough to probably kill a couple of trees on the bear's offside.

Friends and Customers, 08-18-20


All shooters are being inconvenienced with what is happening to our society and the rush it is causing on ammo supplies. We have LOTS of ammo in stock and are making more at a huge volume on a daily basis. If our web site allows you to order any item, that means it is in stock—WE DO NOT TAKE ORDERS FOR ITEMS WE DO NOT HAVE! So, please do not email and ask if items are in stock. If they aren’t, the shopping cart will not take your order.

We have hundreds of customers to get orders to on a daily basis. In order for us to accomplish this for our customers, we ask the following.

  1. Be sure of what you are ordering. You are going to get what you ordered.

  2. Do not contact us and ask to change an order you’ve already placed. When we manually change orders it requires a lot of time that we do not have during this rush and it keeps us from serving all of our customers. If you’d like to change an order, we can no longer do that till things slow down, so simply place another order for more product, but PLEASE, NO MORE CHANGES after the fact!

  3. We NEVER have and never will take ammo exchanges or returns and then turn around and re-sale that ammo to unsuspecting customers as factory new ammo—this is not safe nor is it fair to customers who are buying what they think is new and safe ammo. No ammo is tamper proof! So please stop asking to exchange or get a refund for ammo you ordered, but have changed your mind about.

  4. Please do not contact us and ask for tracking numbers or “when will my ammo ship”? Our system automatically emails out tracking numbers on the orders we ship each day, however, because these emails are coming from a corporation shopping cart, many of these emails may go to your spam folder……..please look there. If it is not in your spam folder, that means we have not yet shipped. At current order rates, we are shipping within 5-7 business days of the time an internet order is placed. Please sit tight. Your ammo will arrive at the same time if you track it or not and will certainly arrive later if we are swamped answering questions instead of getting orders shipped. When 30-50 people per day send emails asking for tracking information and we have to pull that information up, then type it out and email it, it takes a huge portion of our work day that we should be using to ship those orders to customers in need. Please leave us alone so we can serve all of you. (ship to you) It’s a bit selfish, during times of shortages, when so many folks need to protect their families, to slow us down because you ordered carelessly or want to change your order. Right now, we expect you to do your part to help us all get the ammo we need in our troubled country.

These measures are hopefully temporary and will not be needed for long as we enjoy the interaction with our customers, so please, for the time being, be mindful of all those others who are also trying to get ammo during what I think is a societal meltdown/emergency. Hopefully, we can serve you all. We want you and your families to be armed and safe and we wish you the best during these trying times. My biggest concern is that things will worsen yet more, for a while. Until things straighten out in our government and society, we will have to streamline our customer service in order to serve all customers. Thank you for your understanding.

Good shooting and God bless,

Tim Sundles
