MDT LSS XL shines during backcountry hunt in New Mexico, Here is a quick update on the McGowen pre-fit barrel project.

For several reasons, this cartridge was not accepted by the military, but Remington chose to introduce it commercially as the .222 Remington Magnum in 1957-1958.
I’d never recommend using loads developed in any bolt action rifle for a semi automatic rifle. The Lee Factory Crimp die also works very well and provides a reasonably uniform crimp, even when using cases that are not all exactly the same length. For testing and evaluation purposes, I mounted a Harris bench rest bipod and a TRACT TORIC 3-15 scope with Warne rings on my Ruger American. Since this rifle feeds from an AR magazine, OAL was limited to 2.250″ and the long heavy bullets were off the table. Average five-shot group size for all ten loads was .909″ (.868 MOA). Well I loaded up 3 different charges. New Hornady cases were used exclusively here and were uniform in weight, length, flash hole size, etc.
One way to accomplish this is to purchase a new firearm.
Sure, the industry sells a boat load of it. I’ve had fantastic results with their 6.5 Creedmoor brass, finding it durable and capable of great accuracy for one of the lowest price points on the market. In 1957, the Armalite AR-15 rifle was in development, and the .222 Remington case was lengthened, its shoulder moved forward and its neck shortened to create a new experimental cartridge that would offer greater performance and properly function in the gas-operated action.

The accompanying data is intended for .223 Remington chamber dimensions and includes bullet weights ranging from 35 to 75 grains. I sort by bullet and then by max velocity. Savage Arms Inc. bolt-action rifles produced since November 1, 1995, including the Axis, Models 10, 11, 12, 16, etc., have been fitted with 1:12, 1:9 and 1:7 twists, though it seems that of late the company has settled on the 1:9 twist as standard.

Select data that corresponds with a rifle’s twist rate to achieve top performance.
Heav-ier bullets were excluded, as I am unaware of any commercially made .223 rifles with a twist rate faster than 1:8 (with the exception of the previously mentioned discontinued Savage rifles), which is generally necessary to stabilize select 75-grain and most 80- to 90-grain bullets.
While these guns are fun, and sometimes accurate, they don’t seem to do the cartridge justice.

Traditionally, it propels a 55-grain bullet at 3,240 fps – a notable increase in velocity and effective range when compared to the .222 Remington. Of the powders used to develop the accompanying data, there is not a single right or wrong choice, as all gave respectable accuracy and velocity.
