I purchased a new M12 BR (dual port) rifle to shoot F Class style and had it rebarreled to .284 Winchester. Now I find out that to really be competitive I need to load 4 or 5 grains above max (H4831 SC) using Berger 180 VLD's to get to 2800 fps. And I have been told that the action will not hold up to the pressure? Anyone tell me if I made a serious and costly mistake going with Savage? :confused:
i don't think you made Mistake. What kind of powder weight are you talking about? 59 grains? Is your barrel chambered for that specific projectile?
Eric....The mod 12 action is surely more then strong enough.Quote:

to the 7 Sherman as of late. Robin will be straight with you on the
.284.
I would first ask if you have had the rifle out in competition yet? And how much have you shot in competition before this?
I would not be concerned with getting that last 100fps of velocity until I knew I could shoot to an adequate level to take advantage of that last bit of speed.
Downeast, You are the victim of competition snobbery, if not stupidity. Your M 12 action is not weak. Yesterday in competition, I beat actions that cost 5 times what mine cost.
It’s not the arrow, it’s the Indian ;)
First off, You should only load your ammo to whatever your accuracy node is, and I highly doubt it will be 4-5 grains past any book maximum load. Velocity doesn't equal Accuracy. If you can't safely get a velocity / accuracy that allows you to shoot that bullet to the distance you're trying to shoot, try shooting a lighter weight bullet.
Downeast, what are You using as max load, and what is the source of the data. Some manuals are famously low. I have loaded 56 grains of H4831SC in Peterson brass with no indication of pressure. If You don’t already know, I suggest You learn to detect pressure “in your rifle”, and test from low load to “your max”. You will find “your” accuracy node/nodes somewhere in there. Many winning shooters are successful shooting low nodes. There is a lot of talk at matches and on the net. The best information is that which You discover Yourself, with Your equipment. Be Safe!
Downeast, if you were loading 5 grains OVER a real-and-correct maximum load, the primers would blow open the pockets, you'd have a tiny mess in your action when you opened the bolt, and the cases would be useless.. How many loads do you get from your cases?
