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.

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 .

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.

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.

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.

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.

I thought that was ticking you off.
