Top Benchrest Shooter Lou Murdica Talks With LoadDevelopment.com

When it comes to reloading for precision and accuracy, nowhere is it more important in precision rifle shooting than in benchrest shooting disciplines.

Any seasoned shooter knows, once your rifle is built correctly, and your shooting method and technique is perfected, the accuracy comes down to consistency, and consistency in ammunition, comes down to the components and the reloading method.

What sequence do you follow when reloading virgin brass?

First thing I do with virgin brass is run it in a full Length sizing die without bumping the shoulder. Then I expand the neck and then neck turn it. Then size the neck. Then I load the brass and fire form.

What sequence do you follow when reloading fired brass?

First thing I do is anneal it with an AMP Annealer . Then I put it in a PMA tool Driver and case holder in my drill, and clean it with Scotch Brite. Then I size them in a bushing die and bump the shoulder back .001 to .002. Then I trim the length and then debur and chamfer for the mouth of case. Then I wire brush the inside of the neck. Then I use a cotton for swab with Molly on it and put it inside the neck. Lastly I clean and uniform the primer pockets before loading.

Do you anneal your brass and why?

I anneal every time with the AMP Annealer. Because it’s proven in the tunnel it makes a difference in accuracy.

What caliber do you shoot with and why?

In F-Class – Norma Dasher ,284 , 308, 300 WSM ,300 BBM

In ELR (Extreme Long Range) – 10×100 BWA

In Benchrest – 6 PPC , 30 Stewart, 22 walldog, 22 Lapua rimfire ammo

I find all these Cartridges to be very accurate, and have done well with all of them.

What does your reloading equipment consist of?

In the tunnel I use an Area 419 Zero press, and AMP Annealer, and AMP Press and an AutoTrickler powder measure.

My dies are Wilson seating dies, Redding type S bushing dies or custom dies.

What load development method do you use to find a new load?

I work up my load using a powder that fills the case.
I start with bullet making almost a square mark from the lands of the barrel
Then I load the powder on the light side and shoot 2 shot groups working up in powder 1/2 grain at a time until I start to see pressure signs.
Then I look at the 2 shoot groups and shoot 3 shot groups of the loads that look good.
Then I shoot 5 shot groups again from those that look good.
I take the best group and then back off the lands .003 at a time and see if it can improve groups.

Do you do load development before, during or after barrel break in?

I brake my barrel in whilst fire forming brass, before doing load development.

What components does your rifle and optics that you currently use, consist of?

For my F-Class rifles I use:

Cerus rifle stocks
Kelbly actions
Shilen and Bartlein barrels
Flavio Fare triggers
March scopes

For my benchrest rifles I use:

Kelbly and Scoville stocks
Kelbly actions
Flavio Fare triggers
Shilen and Bartlein barrels
March scopes

For my rimfire rifles I use:

Kelbly and Cerus rifle stocks
Kelbly actions
Shilen barrels

What do you feel are your biggest factors resulting in your consistency?

Good components
The proper rear bag
Good load development
Lots of behind the gun time
Good Bullets are a main factor, Without a good bullet you will not shoot good.
Good optics, If you can’t see good you’re not gonna shoot good.

What rear bag are you referring to when you say the proper rear bag, and what front rests do you use?

One of the most important things I’ve found out shooting in the tunnel is the importance of the rear bag, and how it will cause flyers if it does not fit right.

In benchrest I use a Lenzi front rest and rear bag. In F-Class I use a Seb front rest and a Lenzi bipod and Lenzi rear bags.

Are there any other points you may want to add?

Don’t over size your brass.
If you’re not using an AMP annealer, you’re better off not to anneal.
Keep your gun clean.
