Sunday GunDay: Varmint Adventures Using Many Cartridge Types

This photograph and all images for this story are by Bill White, aka “CT10Ring” in our Forum.

AccurateShooter Forum member Bill White (aka “CT10Ring”) is not your typical member. For 37 years, Bill worked in NYC as a studio photographer specializing in still lifes and products. A neighbor visiting Bill’s home in Connecticut with a .270 Sako inspired Bill to revive his interest (obsession?) with shooting after a 25-year drought. And he owns a few Sakos now! With his gun hobby renewed, for many years Bill drove to the Western USA to shoot long range steel and a LOT of prairie dogs in season. He loved the life of the varminter, so it made sense for him to move West after retiring. He choose Idaho as his new home.

From his Idaho base, Bill enjoys long-range target shooting. But his favorite gun pastime has been varmint hunting in nearby states — the Dakotas, Montana, and Wyoming. Bill found prairie dog shooting rewarding and mapped out a western circuit route of ranches and National Grasslands in SD, ND, MT, and WY. Every year he loads up his truck and hits the road, often doing a grand circle route, visiting prairie dog havens in multiple states. In this article we feature photos from Bill’s annual “grand circle” varmint safari.

For his many cartridge types, Bill learned about reloading methods, loads, and vendors (and more) primarily from AccurateShooter.com. We start today’s story with the biggest caliber rifle he shoots regularly, his 6.5-284 Winchester. Bill favors this rig for his long-range steel shooting. He also uses it for prairie dog shooting, but only “sparingly”, because he wants to preserve barrel life, and he has many other dedicated varmint rigs.

6.5-284 for Long Range Steel Targets (and Sometimes Varmints)

In his home state of Idaho, Bill likes to shoot steel at long range. For distance work, Bill favors his McMillan-stocked 6.5-284 Win. This rifle was crafted in 2012 by Bob Green of York, PA, using a 1:8″-twist 28″ Krieger HV barrel (.298″ neck). The trued Rem 700 action was purchased from Long Rifles in Sturgis, SD. Bill did the Cerakote and bedded the action. For his 6.5-284, Bill loads 139gr Lapua Scenars, H4831sc powder and BR2 primers. He shoots both steel and varmints with this rifle, but the varmint work is limited because the 6.5-284 cartridge tends to be a barrel burner. The photo below from an Idaho range was taken near a 500-yard target, looking back at the firing line.

In the Varmint Fields — Traveling Light

Once situated, Bill (shown above) prefers to walk to Prairie Dog towns with a shooting mat, two bipod-equipped rifles slung up, rear bag, water, and his trusty Leica 10X42 GeoVid binoculars. While he has used a portable bench, he prefers to shoot from bipod, firing down from a mound if possible. This allows him to set up a line-of-fire that minimizes cross-wind effects. Bill notes: “While I often start early, end-of-day shooting has worked worked well for me. A setting sun shows targets better, the wind is usually down, and it’s not so hot. Often you can spot the bullet trace and that’s fun.”

Eight Great Varmint Cartridge Types — .204, .224, .243 Calibers

Here is one of Bill Reid’s 6mmBR (6BR) rigs. Like his Sako 6 PPC, this is exceptionally accurate.

Bill has a large rifle collection, most of which see duty in the varmint fields of Montana, North Dakota, South Dakota, and Wyoming. Here are his key “take-aways” for his eight favorite varmint chamberings: .204 Ruger, .223 Rem, .22-250, .22 BR, .22-243, 6 PPC, 6mmBR, and 6-6.5×47 Lapua (aka 6×47).

.204 Ruger — This delivers great velocity with the little .20-caliber bullets, with mild recoil. The .204 Ruger easily reaches out to 400 yards, but heavier winds do move the tiny bullet around. Tremendous splat factor under 250 yards. I use Sierra 39gr bullets with IMR 8208 XBR in a Sako 75. Even now, .204 Ruger ammo is relatively easy to find.

.223 Remington — Probably the most popular centerfire rifle round in the USA, the .223 Rem offers inexpensive brass, and is a great choice for AR-15 owners. If you run short on ammo, you can find it nearly everywhere. I often bring one AR-15 and one .223 Rem bolt gun on varmint safaris. My Rem 700 5R 1:9″-twist barrel likes 53gr V-Max bullets.

.22 BR — My .22 BR is my first choice for most prairie dog missions. Accuracy is superb with necked-down 6mmBR Lapua brass — quarter-MOA and blazing fast. With the right twist rate, this chambering can shoot anything from 40gr FB bullets to 80gr VLDs. Load development is easy. Below is my .22 BR ammo for another varmint trip. I use 55gr Sierra BlitzKings with Varget in my 1:12″-twist Shilen-barreled rifle. 60gr Bergers are very accurate with a fairly flat trajectory for useful distances.

.22-250 Rem — A classic varmint cartridge, the .22-250 with 50gr V-Maxs delivers spectacular hits. If three P-Dogs happen to be lined up, I’ve witnessed one .22-250 shot take ‘em all out with a triple hit. I currently have five .22-250-chambered rifles: 3 Sako 75s, one Rem 700, and a single shot Nesika that shoots tiny groups. I favor the very deadly Berger 52gr Varmint HP. Making a custom .22-250? With a 1:8″-twist barrel you can use the full weight range of .22-cal bullets, while spinning the lighter bullets fast for “red mist” effect. Remember this cartridge can be a barrel burner. Don’t shoot too many rounds too quickly.

.22-243 Win — This wildcat is even more potent than the .22-250, delivering devastating results on P-Dogs. Run a .243 Win case slowly through a full-length .22-243 die, with plenty of lube to form the brass. I start with Lapua .243 Win brass. There can be some issues necking-down the brass. Watch for donuts forming at the neck-shoulder junction. I bought my .22-243 rifle not sure how it would perform. But now I love shooting it. My .22-243 delivers half-MOA groups with 41.0 grains RL-22 and Hornady 75gr Amax bullets. With those 75-grainers, it’s great in the wind and good to 600 yards easily.

6 PPC — You may consider the 6 PPC a benchrest competition cartridge only, requiring fire-forming. However I have an original Sako 75 single-shot 6 PPC rifle that I load with Sako-headstamp 6 PPC brass (see below) so no fire-forming is required. This Sako 75 came with a test target that measured 0.113″! With my 6 PPC Sako, I found that 58gr V-Maxs, pushed by Vihtavuori N133, are potent out to 300 yards.

6mmBR — The 6mmBR Norma (6BR) offers a nearly unbeatable combination of accuracy, efficiency, and tunability. With the 6BR and a fast twist barrel, you can shoot everything from 40gr flat-base bullets to the latest 105-110gr match bullets. I load Lapua brass, Vihtavuori N135, and Hornady 58, 65, and 75gr bullets for my Krieger 1:14″-twist HV barrel. While this cartridge is capable of long-range accuracy, I usually limit my 6BR shots to 350-400 yards.

6-6.5×47 Lapua — In this story’s lead photo is my 6-6.5×47 Lapua varmint rifle, with Surgeon action and Manners stock. I Cerakoted the barreled action and then bedded the action. Shown below is 6-6.5×47 ammo I loaded for recent testing. Note how I separated different bullets and powder loads into multiple, labeled bags. Hodgdon H4350 is a great choice for this cartridge — 39 grains H4350 with 105gr Amax was the winner here, but 88gr Bergers also shot well. This cartridge has tremendous “critter dismantling” abilities out to 600-700 yards.

Six Tips for Novice Long Range Varmint Hunters

1. Take twice as much ammo you think you may need. The fields could be particularly rich, or, because of wind or other variables, you may have far more misses than expected.

2. When possible, set up with the wind at your back (or, alternatively, directly ahead). This will minimize the effect of cross-winds. Set up a stake with a ribbon to show wind direction.

3. Bring at least two rifles. Ideally one would be a low-recoil rifle with cheaper components for the closer shots. Then bring a rifle with higher-BC bullets for longer shots where wind is a bigger factor.

4. Check the weather before you head out. Prairie dogs like sunshine and calm conditions. If a cloudy, very blustery day is predicted, considering staying in town and cleaning the rifles.

5. Bring plenty of water on a trip. An adult male should be drinking at least 64 ounces of water (or other liquid) every day — more if it’s very hot or you are sweating a lot.

6. Preferably always hunt with a companion. If you do go out solo, have a Garmin inReach SatComm/GPS for emergencies if there is no cell coverage in your location.

Veteran Varmint Hunter Shares his Secrets

Where to Find Abundant Prairie Dogs — Generally, black-tailed P-Dogs are found in the Western high desert, in the same states/areas where cattle are raised. You’ll find good hunting in Montana, North and South Dakota, Colorado, and Wyoming. There are good hunting grounds on private ranches, BLM tracts, and U.S. National Grasslands. To find specific locations, I’d suggest calling the USFS, BLM, and State Fish & Game. Some have lists of ranches that allow P-Dog shooting. Give the agencies a call before your trip and then check in with ranchers. IMPORTANT: You need a current hunting license in some states.

How to Connect with Ranch Owners– A good varmint adventure can begin with a local connection. Stop into the local Ag/feed store and the town breakfast spot. I bet you’ll find some retired ranchers having coffee together who may direct you to a place that needs rodents thinned out. Let’s say you’re in Roundup, Montana. Stop by a local store and ask what ranchers allow PD shooting. Keep in mind that ranchers may be wary of allowing a total stranger to sling lead on their place. Show respect and if you had a good experience, send a thank-you note. A guided shoot is worth considering — the outfitter will know where the P-Dogs are and he has arrangements with landowners. He may even supply benches. I’ve taken two guided trips, with excellent results, one near Sturgis, SD, and the other on Sioux tribal land near Rosebud, SD.

Getting Set Up — I start early in the a.m. to mitigate mirage. Plus there is usually less wind at that hour. I prefer to drive to within half mile or so of a PD town, then walk and shoot prone. Most shooters like to set up a rotating bench on a knoll. This is a tried-and-true way to shoot long distances accurately, especially if you are on top of a hill and can shoot 360 degrees. I once shot from a rotating bench, but I prefer walking now. Some country is quite stunning and that’s half the fun — being out in nature. But yes there are negatives to shooting prone — ground hazards and tall grass can impede your vision.

Equipment for a Serious P-Dog Safari — In the field, I normally carry two rifles with Harris 9-13″ bipods, backpack, a rolled-up shooting mat, at least two liters of water, food, ammo, two rear bags, and binoculars. A good laser rangefinder comes in handy. If you prefer shooting from a bench you may want to have a front rest and a spotting scope. Many guys will shoot prone from the bed of a truck. That gets you off the ground without the need to haul around a heavy bench. But some locations restrict vehicles. Before a P-Dog trip, I make a detailed pack list and check off as I load my truck and camper. I would suggest bringing waterproof rubber or muck boots. June in South Dakota can be cold and wet, and the mud there is not to be believed. Don’t attempt to drive off road in it!

It’s good insurance to bring an extra 5 gallons of fuel for your vehicle in a jerry can and 2 gallons of H20. There may be NO shade for miles and dehydration is a real possibility. Having a couple heavy duty tarps will provide a sun shade and cover your gear in a rainstorm. I bring a 16″ X 20″ plywood target backer, a stand, and paper targets. This allows me to check zero on each rifle before I head out to the Dog Town.

Taking Photos on Shooting Adventures

Bill knows a thing or two about taking pictures, having been a professional photographer in NYC for many decades. He uses modern digital cameras for both his outdoor and indoor work. Most photos in this story were taken with a Canon EOS 5DSR MKIV. We asked Bill for some tips on taking good photos. Here are his FIVE Top Tips for Photography:

1. Take photos in the early a.m. and later p.m. when the light has definition. Mid-day results will not be so nice.
2. Use the highest-resolution camera available that fits your budget. Yes lens quality, focus, and exposure controls make a big difference.
3. When feasible, shoot using a manual setting with the lens wide open (for shallow focus). Set the focus on the most important object/subject in the frame.
4. Photoshop is useful, especially when RAW images need to be corrected to show the scene more faithfully, or enhance it.
5. After you take a picture, before you post it on social media, learn to crop the image, straighten the horizon, and do other basic fixes. This can make a big difference.
