Reloading to factory like specs?

Because they mostly don't go that fast in real life. And believe me, if factory loads will do it a reloader can also do it. You're listening to the wrong people.
 
The velocity printed on the box of rifle ammo is supposedly obtained in a very strict testing environment with a specially made custom testing 29" barrel etc.

99.9% of people who buy that ammo will not reach the listed velocity because they are shooting from actual rifles instead of a unique test platform.

There are some exceptions. But the general rule is, you're a fool if you think you'll actually reach the listed velocity of store bought rifle ammo.

It's kinda like advertised MPG on new cars, they get those numbers only in very strictly controlled test environments. But you'll never actually get the MPG they say it gets. With very few exceptions.
 
As I have heard there are powders that are only available to the Mfg and not available to the public, Which might make duplicateing factory figures impossible.
Ever look at reloading manuals it usually list barrel length used for testing if your individual barrel is longer or shorter your velocity could be higher or lower then published data.
To the original poster dont take my word for it but if you where to stick to published load data and used only the recommended STARTING LOADS ONLY you should be good for ALMOST ALL MODERN FIREARMS in good safe working condition. WARNING!!! WARNING!! use this advice at your own risk WARNING!!! SEE there is that liability thing.
For more info call John Walton down at Gunstop Reloading down in the 494 area better yet stop in a talk to him if you happen to get down towards the cities, For many of the local reloaders he is considered the guru and has forgot more about reloading then most will ever know no disrespect guys John is good.
Just dont let him sell you any once fired primers

Johns attempt at humor when talking to new customers.

Oh and when it comes to reloading do not believe anything you read on the internet includeing anything I write. SORRY guys we have all seen miss information out there.
ALWAYS reference published reloading info and its not a bad idea to cross reference several sources.
A good primer for getting into reloading is THE ABCs OF RELOADING and is often available at most public libraries and covers many topics of reloading.

In a 23" Shilen barrel with a tight chamber I have fired these same factory loads over a chronograph more than once. My speeds were more in the 4150 range and not any more than that. Best I have done with handloads is around 4100.

You really do beleive all the advertising you read ?
 
Reloading for safe use in all rifles of a particular cartrage is easy. For example using a 223 remington. Full length resize the brass with the same head stamp. Trim all to specification. prime all of it with the same batch of primers, use a very consistant dropping powder. I would choose a ball powder. Pick a bullet with canalure groove. Set over all length to standard. Crimp case/bullet with collet crimper. Powder weight determination is simple once bullet has been chosen. For example a mid speed ball powder at about mid pressure with a moderate speed about 2900-3000fps with 55gr bulk soft point bullets. As long as the load cycles semi auto rifles reliably and is consistant in accuracy you are good to go.
