Norma Golden Target Winchester Ammo. Federal Win.Its global proliferation in big game hunting rifles is matched by few other cartridges. Nearly every target shooter had his teeth cut on a Winchester. While there are flatter shooting and more powerful cartridges on the market many of which are based on the Winchesterthe Winchester fits the bill for most applications- plus factory rifles and ammunition are readily available.

The rifle was built with the following parts ordered from Brownells :. Brownells also provided the four types of ammunition used in this test:. I did not true blueprint the action prior to threading and chambering the barrel.

I also took the time to groove the barrel in one inch increments from Headspace was measured at 1. Ballistic data was gathered using a Magnetospeed barrel mounted ballistic chronograph. At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. Average velocity and standard deviation was logged for each round.

Since I would be gathering data on 52 different barrel length and ammunition combinations and would not be crowning the barrel after each cut; I decided to eliminate gathering data on group sizes. Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed.

The barrel was cut off using a cold saw. The golang slice of slice protocol was repeated for the next length.

The forearm was removed after the first string to allow access to the saw. Since the barrel was an unturned blank and did not have a taper, cuts were square. All shooting was done from a bench, with a Sinclair rest and rear bag. These graphs assume a 1. Notice the rounds have similar external ballistics with the different barrel lengths out to yards, past the differences become significant. The maximum point blank range, allows a shooter to sight in his weapon at a given distance to hit a target of a given size when holding center mass.

My calculations assume a 1. Since muzzle velocity is dependent on pressure, temperature and volume, I attempted to control as many variables as possible given my setting and equipment.

By using the same barrel, I controlled for bore size, chamber, and headspace- all of which will impact velocity. Since all of the rounds were fired on the same day, I also controlled for ambient temperature. I did not control for barrel temperature. The barrel did heat up during firing. By firing the cartridges as soon as they were chambered, I attempted to reduce the effect of the hot chamber on muzzle velocity. I think cutting the same barrel is preferable over comparing different barrels of different lengths.

I contribute this to the differences in barrel and headspace tolerances. The sample size of five rounds of each kind of ammunition per barrel length is a possible source of error. However, testing indicates it may not be as much as initially thought. Velocity loss per inch of barrel was. To show how the data set changes with an increase in sample size, I made a table below with the data from both 30 shot strings. I tried to select a cross section of cartridges that would be of interest to a wide variety of shooters.

The inherent accuracy and versatility of the sporting version, the Winchester, released in the early s, saw it gain widespread popularity with both target shooters and hunters.

It's designed so that it won't obscure the target even at extreme long ranges. The Winchester has been described as very flat shooting similar to a 6. The Extreme Point bullet features an oversized impact diameter.

With the wrong bullet gr Match should not be used for hunting: It zips right through without expansion. The 6. In ballistics catalogs the point of maximum bullet rise is often called the mid-range trajectory MRTor sometimes the maximum ordinate.Take that lazy, rounded corner, degree.

It was released by Hornady ina few months after. Capable of being fired from the same magazines through the same firearms as the sad.

A higher ballistic coefficient means the projectile slows down less during flight and is affected less by the wind. At the same time, a lighter projectile means significantly less felt recoil and easier spotting of your own shots. Compared to a typical.

These two factors alone massively extend your ability to hit the target or to take an ethical shot on an animal. While porky. At 1, yards it can have twice the kinetic energy.

Sorry, this website is not available for your Country.

I do a lot of LE and military work. I've never had a complaint about accuracy or have seen the need to use anything other than a SAAMI reamer. It works every time, all the time. WSnyder, Thank you for the print. Dave Tooley, I appreciate your comments. It appears for the intended application, getting too wound up about the reamer is unnecessary. Dave- how much neck clearance is there on a saami reamer?

Seems like i looked at my jgs print and i couldnt believe it had that much but i cant remember. Originally Posted by Dusty Stevens.At this particular point in time the US Military had fallen back into the cycle of disbanding official snipers among its combat forces as well as sniper training programs.

These were all chambered for the old US military standard Springfield. When tensions rose in a small country in South East Asia called Vietnam and the US once again found itself in a shooting war, both the US Army and the USMC had to rush their sniper programs back into action, but they soon discovered that not only was their training lacking, but they also did not have any adequate equipment to issue their new sniper units. The USMC literally raided the armories of their bases around the world to get any suitable Winchester M70 with a heavy barrel that they could find.

It was clear to both branches that something had to change, and change quickly. The USMC decided they wanted to incorporate a bolt action rifle and performed a quick evaluation of what was immediately available on the commercial market that might work and in adopted the Remington model combined with a Redfield x40mm accurange scope. This setup was known as the M The US Army was just a little bit later and went the route of the semi-auto rifle and took a modified National Match M and converted it to a sniper rifle.

The Army also topped their rifle with a redfield scope but with a unique mounting system ART. This sniper weapon system was known as the XM In both cases the military felt it was prudent to adopt a cartridge that was a NATO standard and after some initial testing with the 5. When the different branches were evaluating the various different rifle systems available and trying to determine which to adopt, they were also at the same time evaluating ammunition and trying to determine complimentary ammo to use.

It was, and is, widely known that the rifle is only as good as the ammunition it is shooting. Luckily for them, when the 7. In and systematic testing was conducted at Ft.

Benning Georgia using experimental M14 National Match rifles to determine the best load for velocity and accuracy, and by the load had been designated the XM, with the X indicating experimental. This bullet was manufactured by Lake City and was based on the International Match bullet. The boattail was a 9 degree taper and was.

The original specification weight was gr but as time progressed and the tooling wore out, that weight began to spread from — gr. The claimed ballistic coefficient of the bullet is.

The case on the M ammo was a match grade military case produced by Lake City and it originally utilized the percussion primer No.

By Lake City had changed to exclusively use the IMR as it was easier to clean the residue from bores. The overall length of the cartridge was 2. The early M ammo was noted to be accurate with very few complaints and the ammo made a good compliment to both the M40 and M21 sniper rifles and proved quite effective in combat during the Vietnam conflict.

As time wore on the quality of the M Match ammunition began to deteriorate and in as early as the USMC actually began some performance testing and then prepared a formal report about the need to improve the accuracy and quality of the M ammo for combat sniping.

As a result of this and other complaints from combat troops, Frankford Arsenal seriously looked into improving product performance by updating manufacturing equipment, but there was no improvement. In the military tried to also improve the performance by increasing the technical requirements of the round and again, there was no improvement.

The two biggest changes was the change from match grade brass to standard combat grade brass, the same as used on standard M80 machine gun ammunition. The other change was the switch from the primer No. These two changes had significant negative impacts on the performance of the ammo, and no amount of changes to specification or tooling would be able to help.

After the USA pulled out of Vietnam the USMC had made the commitment to continue their sniper program during peace time and they continued to improve their equipment. The US Army, on the other hand, had once again disbanded their sniper program at the cessation of hostilities and it was the marksmanship units that had to lead up the pursuit of better equipment for the Army.

Because of these results a new load was developed called the M The design was simple, put the gr Sierra Match King bullet on the same M brass and powder. Because the Sierra Match King SMK bullet had a hollowtip as Nordkraft film analyse byproduct of production, it was not regarded at the time as being acceptable for fanfiction lemon klaus wolf use in terms of abiding by the Laws of Land Warfare.
