I am finding it a little hard to get 25-06 brass up here in QLD but 2 days ago I obtained a pack of 100 and was wondering if
anybody has had any bad experiences with it
The reason I ask is that there is 3 more 100 packs available and if norma brass is good I will buy them and that should do me
for guiet awhile.
Cheers

Really not familiar with that cartridge but i would be thinking of dropping back to about half way between your min load and the load you have now. Load about 5 each in either 1/2 grain or 0.3gn increments and shoot some groups. See where it is tightest and watch for pressure.

The Norma (if similar to other cartridge sizes) will be heavier than the Rem brass and so have a different capacity. It does have the potential to throw the load out a bit so in my book it's easier to just run a test session than it is to find out in the field that POI or group size has been effected. It may not, as you have found BFS, but it also may.

Then there are other that would say for the same parameters that every 3-5 firings and annealing should be done. Then there are others that have expensive machines that they are either selling or those that have bought them and they would say after every firing.

I am only passing on information no need to try and argue the point with me. In fact this topic was recently brought up on ozFclass so have a look over there and you can argue with some of the countries top shooters.
In my custom guns the amount the neck size changes is next to negligible. There is no feel when resizing and I often wonder if it has changed. The neck opens only enough to release the projectile.

I'd be willing to bet that a direct swap over load will no longer shoot the 1/2MOA you are currently getting. Might still be under a minute but I'd say there will be a difference. Depends how fussy you want to be. I can get very fussy indeed!
