Range Trip

[onlybrowning]

I went to the range this evening with a friend for some load development. I posted a week or so ago that I had found a good load for my .325 WSM Browning A Bolt. I found that my load using a 200 grain AccuBond, CCI 200 primers, Winchester brass, and 62.5 grains of H 4350 to be a great load. I chrony'd it at about 2675 or so. Not very fast for the caliber and bullet weight, but accurate none the less.

I can never leave well enough alone and wanted to see if I could get a little more velocity while keeping accuracy up. I used all the same components, but upped the powder charge by 1 grain for each 4 shot group. I found that 63.0 was good, 64.0 started to lose accuracy, 65.0 was nothing to write home about, 66.0 less than 1 inch, and 67.0 grains was VERY accurate.

I would have never tried to go over the Nosler listed max of 64.5 grains of H4350, but I called Hodgdon and asked them what they list as max. The man on the line said 63.0 is minimum and 67.0 is max. All I can say is WOW! This thing is quite powerful on both ends, and accurate as can be. I didn't get the chrony out because it was drizzling outside, but I am assuming it is in the high 2800's. Just thought I would pass on some info about this cartridge, because it has been difficult for me to find good load info on it.

Kind of weird how the load went in, out, then in again. I found it interesting.

Usually a given powder/combo has 2 accuracy nodes, one being on the lower end, and one on the higher end. Its nice to find a powder that gives you both. I always look for the higher node as I want both, dont we all??

Congrats on finding a new load. Sounds like its a shooter and is what your looking for.

Apples to oranges.
I think if you check, Hodgdon used a Barnes bullet when developing their data.

On their printed data online, that is what they used. I called and asked for specific data using the 200 grain AccuBond. Whether the guy just looked on the computer or actually had that data, I will never know. :lol:

The big difference with Hodgdons is they use alot of Winchester brass while working up their loads, and Nosler uses a lot of Nosler Brass.

Winchester brass is a low pressure component
Nosler brass is a high pressure component.

And that difference IS apples to oranges......
