RE: Does primer and brass matter?
Bear with me, I'm just getting into reloading. Thanks for the help! What are signs of too much pressure?

RE: Does primer and brass matter?
primers flattening, sticky bolt/action after firing, gun blowing up in your face, etc.

There's a few here that could tell you reading Pressure Sign is tricky......

RE: Does primer and brass matter?
Are powder weights pretty much standard for bullet weights? For example, a 150 gr. nosler and a 150 gr. barnes. Would you use roughtly the same grains of powder?

RE: Does primer and brass matter?
A Barnes TSX, TTSX, and MRXare going to operate at a lower pressure and have a higher velocity due to the reduced bearing surface of the bands...so it will tolerate a higher powder charge.
A nosler, having much more bearing surface, will generate a higher pressure due to it's typical construction. Never assume that powder weights will cross match with other bullets without first doing a work up. When in doubt, always play the Safety Card.... |

I dare you to try 97gr of H1000 with a barnes 180gr TSX in a 300RUM. I know I will with a 180gr nosler accubond or partition. Even barnes, the cowboy's of reloading will tell you "no way". A TSX actually has more bearing surface than a nosler partion due to its all copper construction which makes it longer, hence its higher BC. A MRX is a different story. I load Triple shocks in 8 guns and know better. |

Taken from the Barnes website, FAQ's....
http://www.barnesbullets.com/information/bullet-talk/faq/ "What is the Triple-Shock X Bullet and what does it do? Barnes’ Triple-Shock X Bullet offers all the deadly effectiveness of the time-proven X Bullet. Features include all-copper construction, no fragmentation, rapid expansion, 28% deeper penetration than lead-core bullets, and maximum weight retention. The TSX has proven to be one of the most accurate hunting bullets available–a fact countless shooters have confirmed. An exclusive feature of the Triple-Shock X Bullet is multiple, precisely engineered rings cut into the bullet shank. These grooved rings act as relief valves as bullet metal flows under pressure while traveling down the bore. Instead of flowing from the front to the base of the bullet, the copper material expands into the grooves. This results in reduced pressures and less copper fouling. Reduced pressures mean the bullet can be safely loaded to higher velocities. The rings also alter barrel harmonics, greatly improving accuracy." Of course you would have to have a firm grasp on the physics to understand the concept,and it's been well documented that you don't/can't........ |
RE: Does primer and brass matter?
Actually, since I'm not a velocity ho, the advantage I see to using TSX's is the ability to use LESS powder to achieve the normal velocity I seek. Or, using a fuller case of slower powder to achieve a normal velocity...which leads to the load densities I prefer. In either case, the lower working pressure of the loadwith no loss of velocity is the benifit.
But you are an Expert,I'm sure you know better........... |

They are talking about reduced pressures compared to thier X. Anytime your ready, I dare you to match my max loads I achieve with sierra, or nosler bullets. Your only 4 hours away. |
RE: Does primer and brass matter?
ORIGINAL: Rifle Loony But you are an Expert,I'm sure you know better........... Or better yet, lets see if you can match my max velocity. What caliber? 308win, 270, 300RUM,7mmSTW, 7mm08. I am sure I can find a gun you have to do the test. Those loads listed in the barnes manuals under max are max. They are 60KPSI in most calibers. So how is your physics different from mine? |
