Sunday GunDay: Doan Trevor Custom Rifles and Wood Stocks

Doan Trevor custom wookd stock gunsmithingDetail from Doan Trevor rimfire prone stock (Fiddleback Walnut) with Stiller 2500 X Action.

New Mexico Gunsmith Doan Trever is a true wizard with wood. At Doan Trevor Custom Rifle Building, he crafts stunning figured wood stocks, and also builds complete wood-stocked and fiberglass-stocked rifles that shoot as good as they look. Doan is a true master, with a mind for function and an eye for beauty. The ability to hand-craft wood is becoming a lost art. For this Sunday, we celebrate four projects crafted by Doan: two complete rifle, a special F-Class stock built for multiple actions, and an F-TR stock for a Sako action. Visit DoanTrevor.com to view find dozens of other stunning stocks and complete rifles.

Mausingfield America Rifle with English Walnut Stock

Doan told us: “This is a highly figured piece of English Walnut with burls and flowers. Along the bottom of the stock there’s a burl/flower that looks like an owl and one side looks like the Sandia Mountains. This rifle is in 30 PCR. Doan adds: “The owner is enjoying this rifle immensely.”

Walther KK500 (Twin Trigger), English Walnut Laminate Stock with Fiddleback Accents

About this unique rig Doan notes: “This left-handed rifle has two triggers. It has an electronic trigger AND a mechanical trigger. With the wood stock option, the charging cable needs to be modified modify in order to clear the trigger extension to be able to charge. Also, keeping with aesthetics, I made it able to remove the trigger guard in order to charge more easily. Removing the trigger guard does not change the bedding.”

American Walnut F-Class Stock with Figured English/Claro Walnut Fore-End Inlay

Doan explains: “The owner has three actions with the same barrel block mounting system. He wanted to be able to use one stock. I built a bedding system that would accomplish this task. The two pieces of Claro Walnut on the fore-end are mirror copies.”

F-TR Stock for Sako 85 with Johnny Byer Stock Blank

Here’s a handsome F-TR rig. Doan reports: “The pistol grip cap is a piece of Screw Bean Mesquite Wood from my old front yard in Albuquerque. (I live in Rio Rancho, NM now.) Take a look at the bottom photo with the blue background, the rifle doesn’t have any stippling yet. Sometimes, you have stippling as the last step. There’s no room for error when this order of events is necessary.”

Beat the Heat — Keep Ammo Cool During Hot Summer Days

Heat Map USA color chart

The Summer Solstice is June 20, 2021, just a week away. And July is nearly here. That means “peak heat” summer conditions. It’s vitally important to keep your ammo at “normal” temps during the hot summer months. Even if you use “temp-insensitive” powders, studies suggest that pressures can still rise dramatically when the entire cartridge gets hot, possibly because of primer heating. It’s smart to keep your loaded ammo in an insulated storage unit, possibly with a Blue Ice Cool Pak if you expect it to get quite hot. Don’t leave your ammo in the car or truck — temps can exceed 140° in a vehicle parked in the sun.

Ammo cool storage

Bosch Insulated tool caseTo learn more about how ambient temperature (and primer choice) affect pressures (and hence velocities) you should read the article Pressure Factors: How Temperature, Powder, and Primer Affect Pressure by Denton Bramwell. In that article, the author uses a pressure trace instrument to analyze how temperature affects ammo performance. Bramwell’s tests yielded some fascinating results.

For example, barrel temperature was a key factor: “Both barrel temperature and powder temperature are important variables, and they are not the same variable. If you fail to take barrel temperature into account while doing pressure testing, your test results will be very significantly affected. The effect of barrel temperature is around 204 PSI per F° for the Varget load. If you’re not controlling barrel temperature, you about as well might not bother controlling powder temperature, either. In the cases investigated, barrel temperature is a much stronger variable than powder temperature.”

This Editor had the personal experience of 6mmBR hand-loaded ammo that was allowed to sit in the hot sun for 45 minutes while steel targets were reset. The brass became quite warm to the touch, meaning the casings were well over 120° on the outside. When I then shot this ammo, the bullets impacted well high at 600 yards (compared to earlier in the day). Using a Magnetospeed, I then chron-tested the sun-heated ammo. The hot ammo’s velocity FPS had increased very significantly — all because I had left the ammo out in the hot sun uncovered for 3/4 of an hour.

LESSON: Keep your ammo cool! Keep loaded ammo in the shade, preferably under cover or in an insulated container. You can use a SEALED cool pack inside the container, but we do NOT recommend H20 ice packs. And don’t have the container do double duty for food and beverages.

Powder Heat Sensitivity Comparison Test

Our friend Cal Zant of the Precision Rifle Blog recently published a fascinating comparison test of four powders: Hodgdon H4350, Hodgdon Varget, IMR 4451, and IMR 4166. The first two are Hodgdon Extreme powders, while the latter two are part of IMR’s Enduron line of propellants.

The testers measured the velocity of the powders over a wide temperature range, from 25° F to 140° F. Hodgdon H4350 proved to be the most temp stable of the four powders tested. [NOTE: New Alliant Reloder TS 15.5 has also proved very temp stable in AccurateShooter’s range tests.]

How to Use a Collet-Type Bullet Puller

Hornady cam-lock bullet puller ammunition UlimateReloader

When you make a reloading mistake, you may need to “pull down” assembled ammo. The embedded UltimateReloader.com video demonstrates how to use the Hornady Cam-Lock bullet pulling system.

When Reloading Goes Bad — The Danger of Over-Charging
Our friend Gavin Gear of UltimateReloader.com was recently reloading some 9mm pistol ammo with his Hornady progressive press. As part of his reloading procedure, he visually checks the cases — and he noticed that the charges seemed high. Sure enough, his most recently-produced rounds were about two grains over spec. He diagnosed the issue: “I was using a powder measure without a baffle. What happened was, over the course of the loading session, things settled in, and the charge level increased.”

Not knowing just when his powder measure started delivering too much powder, Gavin decided, for safety’s sake, to pull down all the ammo he had just reloaded. Yes that’s time-consuming, but it’s better than the alternative — having a dangerous Kaboom while shooting. With fast-burning pistol powders, a two-grain over-charge could cause a blown case, damaged firearm, and/or serious injury.

Watch Cam-Lock Bullet Puller Used to Remove Bullets from Loaded Ammo:

Use of Bullet Puller starts 4:00 minutes into video.

Gavin says it is vitally important to perform safety checks during the reloading process: “You’ve got to do it — check every single round to make sure there IS powder, and that there’s not too MUCH powder. Double, Triple, Quadruple check your components… and your powder charges. You can’t be too careful.”

To pull down a loaded round, first place the cartridge in the shellholder on your press ram. Then raise the round up into the bullet puller device installed where a die would go. The Hornady Cam-lock bullet puller works by clamping the bullet in a collet when you flip down the red-coated lever. Then, with the case held by the rim in the shell-holder, the bullet exits the cartridge as the press ram is lowered. It takes time, but it’s pretty fool-proof once you get the hang of it. This entire process is illustrated in Gavin’s video, starting near the four-minute mark.

The Hornady Cam Lock Bullet Puller has four (4) key components: 1. Cam-Lock die body; 2. Cam-Lock lever; 3. Stem; and 4. Collet (Caliber-specific).

NOTE: In order to use this tool, you’ll need the appropriate collet for each diameter range of bullets you intend to pull. For example use collet #3 for 6mm, collect #6 for 7mm, and collet #7 for .308 Caliber.

RCBS Lockout Lock Out die Dillon HornadyRCBS Lock-Out Die
A good safety option for users with progressive presses is the RCBS Lock-Out Die. This has a charge detection rod that dips into each case after powder has dropped. You adjust the die to the proper charge height for your desired load. If the actual dispensed charge is too high or too low, the Lock-Out Die senses the problem and stops the press from advancing to the next case (it does this by preventing the ram/shellplate from fully elevating). We’ve used the Lock-out die with success for both pistol and rifle cartridges. It’s sensitive to about one-half grain with pistol powders.

This Lock-Out Die works with Hornady and Dillon progressives as well as with RCBS progressives. It does take up one die station on the press.
