Reloading book error
 

I have one of the One Book/ One Caliber reloading books for 300 win mag and looking at the Barnes section the 165 Grain using 78 grains of RL22 has a muzzle velocity of 3137, but 180 grain has a muzzle velocity of 3103 with 75.5. This does not seem right. Could someone check their reloading manual to validate this, I'm 99% sure this is wrong.

You are not the first person to question the data in the barnes manual.

RE: Reloading book error
 

I've looked at a couple of the loads in Barnes Manual and questioned them myself . I have one of the early editions #3's and don't find the same info in a later edition of the #3 that a friend has . I really believe it is time for Barnes to redo thier Manual and bring it up to date for all the new loads .triple shock ,ect .

RE: Reloading book error
 

crimedog, can you get good groups with Barne's bullets? A friend shoots Barnes and I really like the results on the bullet recovered from an elk he harvested. I tried to work up a good load for my 7mm Rem. Mag. with little success. I get awesome groups shooting the Sierra's with RL-22, but can't come close with Barnes. I tried RL-22, RL-19 and IMR 4831 with my best groups at 100 yards of 1.05". A five shot group with the Sierra's I can cover with a dime. Any suggestions? Oh, the information you have on the 300 Win. Mag. is what I see in my #3 Barnes manual.

RE: Reloading book error
 

The only barnes bullet that is accurate in my rifles is the tsx.In fact they are very accurate in my rifles with almost no fouling.

RE: Reloading book error
 

If the data is correct and 78 grains will only be 3100 fps I may not even try, like I said I suspect the data is wrong. I've found the max load for the Triple Shock and it's 78 grains and it's very loud compaired to other 78 grain loads. I'll cronograph the 78 grain Triple Shock and find out, my gun usually like's 77 to 77.5 of RL22, but if I can't be at 3100 fps what is the point.

RE: Reloading book error
 

3100fps is respectable for a 180gr bullet out of the 300winmag and you should have no problems attaining that with the tsx which will produce more velocity with the same pressure than the standard x bullet.My 300ultramag produces 3380fps with the 180gr tsx and averages 5/8" groups.

RE: Reloading book error
 

Barnes are the cowboys of the reloading world. They have several that make me nervous.

RE: Reloading book error
 

Including one 30-06 load that a certain individual here keeps bringing up even though he has never even fired it himself to verify the velocity or to see if it shows pressure signs.

RE: Reloading book error
 

I thought that was ticking you off.

RE: Reloading book error
 

It appears from this thread that someother very experiencedshooters are also questioning the barnes data.Now why do you think that is?Could experience be a factor?I personally don't advertise a load without testing it myself or witnessing it being tested,and Idon't consider it credible until it has been verified.But then again ,I prefer to deal with fact rather than fiction.

RE: Reloading book error
 

I think someone needs some anger management intervention.

RE: Reloading book error
 

I don't want to get involved in the disagreement. My problem is 180 grain is just a little more than I need for whitetail. I like 165 grain bullets and the fact that max load for 165 is 3137 and 180 is 3103 leads me to think there is an error. Swift data has 165 scirocco at 3126 and 180 is 3031. Serria has 165 at 3300 and 180 at 3100, Nosler BT 165 is 3290 and 180 is 3118. Hornady has 165 at 3200 and 180 at 3000. Speer data on the other hand is similar to Barnes with 165 at 3103 and 180 at 3055.

Roskoe, I know you use the sciroccos in your 300, what velocity you getting with you loads and what is that load, I know you have krieger and hart barrels, and different gunshave different velocitys, but what are you getting.

RE: Reloading book error
 

I never really worry much about weight as long as they shoot good and its acceptable for the my game.

For instance, when I go for moose, I want bullets between 180-200gr to work out for me. If I had a very accurate load at 180 over the 200gr, I would use it. And depending on the bullet, I might even use 165gr if it shot good enough.

For deer, I would use anything that shot well between 150-200gr.

I have had krieger barrels and they do build pressure quicker than any factory barrel I have had.

RE: Reloading book error
 

Why are you getting angry?I guess that comes with being delusional and living in a dream world wherefull sizeweatherby mark V actions weigh less than 2 pounds.It sounds like you getyour load data from the same source as your action weights.:):)

RE: Reloading book error
 

I agree that it sounds wrong, but there are times when a heavier bullet will get more velocity and energy out of a given amount of powder than will a lighter one having less inertia and bore friction. This may well be one example of such an instance.

RE: Reloading book error
 

The data might be quite correct for the rifle used to develop the load, and be very far out of whack in YOUR RIFLE. In fact, it would be a miracle if it were NOT!!

As Bob Hagel said, "a load that proves to be maximum in one rifle might be quite mild in another, AND VICE-VERSA."

Get a chronograph, and test the data in your rifle. Then you will be closer to a correct answer, and not just speculating, or worse yet, depending upon the speculations of others!!

Boy Stubble you are not going to like this!!!

RE: Reloading book error
 

Well, gee whiz! What would you expect the Weatherby boys to say about Father Roy's action design, eh?

Remington had the "three rings of steel" first, a'la 721-722. And, I am aware of some Mark V actions that have had less that all nine lugs actually bearing in the receiver ring when the bolt was closed. Two lugs are all that are really needed.

Even so, the Mark V is a great action. However, I personally prefer one with the Mauser 98-type claw extractor and controlled-round feed. (In a bolt action, that is. Actually, I prefer a good single-shot!)

RE: Reloading book error
 

I think you may have missed the point of the link. The link shows the Weatherby Magnum on a digital scale with the weight of the action and bolt displayed at 35.9 ounces. Stubblejumper said the following about me in aquote:

"I guess that comes with being delusional and living in a dream world wherefull sizeweatherby mark V actions weigh less than 2 pounds.It sounds like you getyour load data from the same source as your action weights.:):) "

I thought it was kind of comical to make such a strong statement and have it backfire on him.

RE: Reloading book error
 

Isn't that 2.24lbs? I always considered the trigger part of the action myself.

RE: Reloading book error
 

Yea it is actually 2.24lbs.His jab was continuation ofthe gun forum debate between the Weatherby Accumark and Remington XCR barrel weight. Stubble had the Weatherby Magnum weight at 50.5oz vs my weight of 35.9oz from Weatherbys web site. At any rate triggers andhardware ect weight are minimal and probably very even between the two guns. The point of my response is the action weight is no where near 50.5oz as he claimed.

RE: Reloading book error
 

Well, I sure don't want to be between this. But Scott I warn that real life measurements in this gun/reloading world usually if not 95% of the time usually is much worse than advertised.

Espiecally in the Bow world. If someone buys a bow cause of IBO speed, they are pretty silly. I suggest the same for guns.

RE: Reloading book error
 

I understand what you are saying about theadvertisingand agree. Especially the bow thing. One of the little known tricks for increasing FPS is toanchor the bow at 70lbs even though the let off weight is say 20lbs and letting it fly. Kind of dishonest really.

RE: Reloading book error
 

It certainly ispart of the action assembly as is the the magazine insert, the magazine followerand spring,the floorplate/trigger guard assembly and the action screws.You don't see them on the scale do you?

RE: Reloading book error
 

Whats not to like.I gave data for the complete action assemblies for both rifleswhich includes the trigger assembly,magazine insert,magazine follower and spring,floorplate/trigger assembly and action screws.You don't see them on the scale don't you?Or did you forget that the rifle needs them to function?:):):)

RE: Reloading book error
 

Who did it backfire on?Perhaps ona very delusional individualthat forgot about the trigger assembly,the magazine insert,the magazine follower and spring,the floorplate/trigger guard assembly and the action screws.Do you see them on the scale.Or doesn't your rifle need these parts?:):)

RE: Reloading book error
 

OOPS that sort of changes things then dosent it!
