‘Quit Neck Sizing’ — Cortina Explains Full-Length Sizing is Better

Full-Length Sizing Erik Cortina Neck Sizing Video

Our friend Erik Cortina is at Raton, NM this week at the F-Class Nationals. When he’s not shooting (or working) Erik produces YouTube videos. One of his most popular videos explained why you should full-length size cartridge brass. In no uncertain terms Erik says: “Quit Neck Sizing!!!” Watch the Video:

Why It’s Smart to Full-Length Size Your Brass

Commentary by Erik Cortina

Should You Full-Length Size Your Cartridge Brass?

Absolutely. Let Me Explain Why…

I have seen it time and time again, shooters on the line wrestling with their rifle trying to get the bolt closed while the wind is switching. They were too focused trying to get their bolt to close and getting their rifle settled back on the bags that they missed the wind switch. Bang… Eight! The straw that broke the camel’s back for me was at the 2017 Canadian Nationals. I was paired up with a young girl and she would try really hard to close the bolt on her rifle. The majority of the time she would get it to close, but often times she could not even get the round to chamber. She was focused on her rifle the entire time rather than on the conditions. When we completed our strings, she had five rounds that did not chamber our of 15! That is way too many!. I told her she needed to think about Full-length sizing with 0.002″ shoulder bump, or Controlled Full-length Sizing like I call it. I told her not to worry about losing accuracy. I told her that I full-length size all my rounds and asked if she noticed how smooth my bolt was and noticed my score. She said yes, they were both great!

Controlled Full-length Sizing Does NOT Harm Accuracy
I have found that Controlled Full-length Sizing does NOT hurt accuracy or shorten brass life. I find that I can focus much more on the conditions when I don’t have to think about chambering a round nor extracting it. It has become second nature. After firing, I keep my head welded to the stock, I open the bolt by placing my thumb on top of stock and rotating hand upwards. I reach in and retrieve spent case, place it back in ammo box, and pick up another loaded round and put in chamber. I verify conditions and when ready, I push the bolt in and close it with my index and middle finger.

With Controlled Full-length Sizing you “bump” the shoulder around .002″ for bolt guns.*

by AccurateShooter.com Editor
For proper Full-length sizing, you want a quality die that’s a very good match to your chamber. For our project rifles we usually turn to Whidden Gunworks which offers both bushing and non-bushing FL dies. And if you want the hot new option, check out Whidden’s patent-pending, click-adjustable FL-sizing die. This gives instant, precise control over shoulder bump. It works great.

*With gas guns, such as the AR10, you may want to increase shoulder bump to .003″ or more. With some benchrest cartridges, .0015″ bump may prove optimal. But .002″ is a good starting point.

Cool Tools for the Reloading Room — Look What UPS Brought

21st Century Tools Concentricity Checker lathe neck turner turning scale UPS

Posting on Facebook, Michael W. said: “Maybe it’s just me but I LOVE coming home to packages from the UPS driver sitting on my deck! Now I can get serious about creating some Match Grade ammunition!” Michael showed off some very impressive reloading hardware, including a 21st Century Shooting “Mini-Lathe” Neck-Turning system, 21st Century Concentricity Gauge, Shars Tube Micrometer, and the A&D FZ-120i Precision Balance. Cool Tools indeed!

21st Century Neck-Turning Lathe — A Gem
The 21st Century Neck-Turning Lathe works great — this is what we use to turn necks. It floats at both ends, so it runs very smoothly. You can use it manually or with power. It gives you very precise, clean cuts with a minimum of case lube. The cutting tool is hard and sharp so you can do large quantities of brass without having to adjust the cutter position for wear. We’ve used a half-dozen neck turners and this 21st Century Unit is our favorite.

21st Century Concentricity Gauge — Smart, Efficient Design
The beautifully-crafted 21st Century Concentricity Gauge is fast and easy to use yet very precise. The twin, roller-equipped case supports slide back and forth on rails so you can measure any size case, from a 17 Fireball up to a 50 BMG. The horizontal dial indicator also slides on parallel rails so you can easily measure any spot on a case or loaded round — from bullet tip (or case mouth on empty case) down to the mid-body. We like to measure run-out on our sized, empty brass on the necks and then measure again on the bullet ogive with loaded rounds. The large-diameter wheel allows bump-free, “no wobble” case rotation, delivering better results than spinning cases with your fingers.

Concentricity gauge uses stainless turning rollers for less friction and more consistent read-outs.

A&D Precision Balance — Ultra-Precise with No Drift
The A&D FX and FZ-series scales are magnetic force restoration balances with 0.001 gram sensitivity so they are accurate to the kernel. This balance will not drift like less advanced, load cell-based digital scales. The scale’s high sensitivity and extreme stability allow you to weigh charges and sort brass, primers, and bullets with much higher precision.

What Gadget Would YOU Like To Have Delivered?
Here’s a question for our readers… What are YOUR favorite reloading tools on currently on your bench? And if you could have the UPS driver deliver a new tool tomorrow, what would you like him to bring? A 21st Century Hydro Bullet Seater (awesome Arbor Press)? Maybe a Whidden Micro-Adjustable Sizing Die? How about the amazing Auto Trickler and Auto-Throw system from Canada? That combines a A&D FX/FZ scale with a powder thrower and microprocessor-controlled trickler. With the push of a button you get a charge dispensed and weighed to single-kernel accuracy.

Buffalo Horizontal Gun Safe — Under Bed or in Vehicle

buffalo under bed vault gun safe horizontal
Now on SALE for $279.00 (20% Off), this horizontal safe normally retails for $346.93.

We like innovative security solutions. The standard “big box” gun safe is not ideal for all situations. Here’s a new gun vault primarily designed for under-bed placement in a house, but it can also be installed in a vehicle. Bolt it to the bed of a pick-up truck or the back of an SUV. The full width is 48″ so it will fit most trucks and many sport/utility vehicles.*

This Buffalo Horizontal Gun Safe offers three cubic feet of storage though it is just 7 inches high. The 46″ W x 26″ D x 5″ H slide-out drawer is secured with a digital lock with back-up key. Under-bed installation keeps your firearms “out of sight but close at hand”. The felt-lined sliding horizontal compartment holds up to 100 pounds of firearms and valuables. This won’t hold a long target rifle, but it’s plenty big enough to hold an AR15 or Shotgun and multiple pistols.

This gun vault features a pry resistant steel door and 14 gauge (2mm thick) steel body. NOTE: This vault is NOT fire rated — it is intended for secure storage and theft prevention only. For added security, we recommend bolting this Buffalo vault to the floor.

Overall External dimensions: 48″ W x 28″ D x 7″ H
Inside Vault dimensions: 46″ W x 26″ D x 5″ H, three cubic feet
Weight as Assembled: 130 pounds


* Vehicle Installation: You need at least 48″ side-to-side clearance and 28″ front-to-back space to fit this vault in a vehicle. While you can lock an SUV, this vault give you an added measure of protection and secures items from view. This vault also ensures compliance with states requiring fireams to be in separate, locked compartments during transport.
