One of our customers, Jeremy Wallace, sent us this great story of how he filled his bull elk tag this year. Jeremy was using a 300 RUM rifle he built using a Northwest Action Works trued Remington 700 barreled action, which he had built by us as part of the Long Range Hunting giveaway that he won! He did a great job with load development and practicing with his rig, and here is the result!
It was unseasonably warm for the third week of October with highs consistently in the mid to upper 60s and the elk movement was slow. We hadn't seen much when late in the afternoon on the third day of a 5 day hunt we spotted 2 bulls in the timber 1,100 yards across from us at about the same elevation (7,600'). The bulls were wandering down the mountain our direction so we decided to lose some elevation and close up that gap. We got down to about 7,300' and the bulls were below us when they started hitting openings big enough in the timber for a shot. This was my third elk hunt but my first chance at a shot so I wasn't really trophy hunting I just wanted a shot. My brother was on the G7 range finder and the wind that was originally blowing around 6mph steadily all day had dropped down to nothing. As the bull approached the last opening my brother was consistently ranging the gap. 737 yards across. The G7 said to shoot it for 693. The guide asked me 3 times if I could make that shot and I assured him that the gun and myself were both up to the task. Then he said its getting late i need you to be sure you can put him down right there. I was. I twisted the turret on the Huskemaw and waited for the bull to hit the spot. When he got there I was surprised at how wide open it was where he was standing. I thought there would still be some brush and small branches in the way but where he was it was wide open. The cross hairs found him high in the shoulder when he stopped. I started applying pressure to the Timney 512 when the gun barked. I concentrated on my follow through knowing my brother and the guide was watching for the results. It turns out it was not needed. After the follow through I was back on the gun just in time to see the hit and hear my brother and the guides report. "He's down, nice shot". It caught the bull high in the shoulder, through the spine and exited out the opposite shoulder. The bulls legs tucked up tight under him and for a millisecond it looked like he was levitating. Then gravity took over and he went straight down on his belly, rolled 4 times down the mountain and only stopped by wedging into a down pine tree tangle. Hes not huge but I had to get started somewhere and I must say I am tickled. I can't say enough good things about the barreled action you guys built for me. Extremely fast, extremely accurate, and pretty darn good looking too. Thanks for a great elk, moose, mule deer, bear, whitetail, sheep, and caribou hunting rig.
Heavy Hitters Outdoors is thinning out the deer population in a big way this season! As many of you know, we recently partnered with this outstanding outdoor adventure program, and we are happy to report that they are out confirming how well these rigs work for all manner of big game hunting. With one shot kills from 100 to over 600 yards so far, they have had nothing but great results from our PMR, NW Backpacker, and Ramrod Hunter custom rifle packages.
This great group of guys is putting in a lot of work to bring you an outdoor show like no other, and we cannot wait to see this upcoming season of incredible episodes. Be sure to check out their website for last year's episodes and give them a like on Facebook to see what they're up to. We'll be continuing to report on their success and will have videos from getting out to shoot/hunt with them this winter, so check back often!
Welcome to the fourth and final installment in our basic guide to precision reloading. Now that we've covered all of the steps and equipment we use to put together high qualitey loads, it's time to go over how we go about deciding what to put in them!
Though load development is an enormous topic and one that is widely debated across shooting forums, this article is going to be quite a bit shorter than it could be. This is because the process we use is already very well described by its creator, on his website found HERE.
It is called the Optimal Charge Weight (OCW) method, and we have used it over and over again to find outstanding loads in a wide variety of cartridges. Dan Newberry gives very practical, easy to understand instructions for how to go about choosing a powder, how to safely find the maximum charge weight, and how to set up a series of test rounds for finding the best load for your rifle. If put together, fired, and interpreted properly you will end up with a load that will not only work great for the rifle you do the test in, but will often work well in multiple rifles of the same caliber. We have found OCW's for several cartridges that we are able to use for test firing our custom rifles and barreled actions, knowing they will nearly always give us a reliable measure of accuracy potential in a given rig.
Over the years of doing these tests, we have developed our own set of steps and tweaks to Dan's method that work best for us to consistently get the results we're looking for in as few range trips as possible. We recommend reading through Dan's instructions and getting a firm understanding of the process before reading the rest of this article.
First, we do what we call the "pressure ladder". Similar to Dan's description of finding the maximum charge weight, we consult the books we have on hand, as well as several internet resources in order to see what others are typically using for the given powder and bullet combination we are wanting to test. Once we have a pretty good feel for the higher loads, we build a string of loads at 0.5 grain increments, often extending to 0.5 to 1.0 grains above the highest load we've seen being used routinely. We then fire them in succession from lightest charge to heaviest, examining each for signs of pressure. (There is a lot of debate on the subject of determining actual pressure in a load and what constitutes a safe charge. In the end, we all have to research it and decide what we're comfortable with in our load development practices. Decide what works best for you and run with it!)
We typically fire the pressure ladder over a chronograph to get an idea of the velocities we're working with, and to look for consecutive charges where velocities are more consistent. We'll also often see a spike or two in velocity that we generally try to avoid running the actual OCW ladder through. We also usually fire them in 3-shot groups, and you'd be surprised how often you can start to see some good groups forming up at the more stable velocity levels.
Then we'll build the OCW ladder according to Dan's instructions, and fire it in round-robin fashion as he describes. One thing we'll do for a bit of insurance is load up 4 shots at each charge level. This extra shot has come in handy on several occasions, in a few different ways. The first is the most obvious, as an extra shot in the event of a called flyer. If everything is going along great and you get a flyer that you're pretty sure you caused, having an extra shot to stack right in with the other two can save the overall look and readability of a ladder. It can also serve to verify a suspected "scatter node" in an OCW ladder. If you have a group or two that just don't look right or you think might be a scatter node, putting another shot into them can sometimes answer the question. If we get a good ladder with a relatively clear result and have the extra shots left over, we'll sometimes take the load we believe to be the winner and the one above and below it and fire all three at a longer range. This can be a bit tricky if you don't have a pretty good idea of the velocities and how to compensate for the longer range, but we've seen 1/2 MOA 3-shot groups at 500 yards even with the completely different charge weights! This is a good sign that you are on the right track to a stable load.
One very important thing to note: follow Dan's advice and do not get distracted by the smallest group(s). Follow the method and do your best to analyze it according to Dan's method.
Once we have what we believe to be an optimal charge weight, the very next thing we do is a seating depth test in the rifle we're working with. We primarily shoot Berger bullets, and have had great results using their seating depth test method, found HERE. Time after time we have seen one seating depth perform a LOT better than the others.
If all goes well we make several confirmation loads and go out for long range testing. If we aren't seeing the groups we'd like to see at longer ranges, we'll step back in to shorter ranges to make sure groups are still fine there. Running several over a chronograph can tell you if you're getting some inconsistent velocities that would cause issues at longer ranges as well.
If you're having trouble reading a ladder or aren't sure you've picked the right load, Dan is a fantastic resource and will analyze a ladder you send him a picture of for a small fee. We've used his services several times and his trained eye can be a huge help when you've gotten too close to the project! Go through the consulting link on his page for more info on getting help from him.
As with all reloading advice, take it with a grain of salt and do more research before deciding on any one method or safety practices. Rifles and reloading are dangerous and you should not exceed your comfort zone with a great deal of experience or sound advice from people who have it. Be careful and ask questions if you have any.
