Powders like Hodgens Hybride 100V and especially Accurate Mag Pro I've been trying to find stater loads for my 6x284. Looking at the Hodgen site and Sierra new manual those loads are weak.They're max loads of H4350 with 87gr V-Max is less then my light load with that bullet???? Is it legal stuff? Any how where do I start with powders like IMR 7828 fo a 90 gr bullet out of my 6x284? Or W-W 780 ,Accurate Mag pro??????????????????

This is a subject that can be long and can be full opinions. I use the Lyman reloading handbook at the basis for all of my reloading.
If you start with a charge that is way to low for the cartrisge, you can have pressure problems. Way too high and you can have dangerous problems.
I am a fan of many powders, but what are you planning on loading for? Do you want to target shoot or hunt?

I don't know why but I like the fire breathing dragon cartridges. Just walked in the door from rifle range shooting my 6x284. Todays powders were RE#22 and H4831 SC behind 90 gr Lapua match bullet that looks like a VLD. Top loads were 56.7 grs of RE#22 for 3,550 FPS with out standing accuracy well under 1/2MOA at 100 and about same velocity with about same weight charge of H4831 SC and also out standing accuracy. I feel like todays rifle performance was best ever. Now for the curve ball. Gun smith says there is significant amount of throat erosion in BBL. I bet I've shot 800 maxs loads through this BBL. All bullets seated well into lands.

Ironworker,
Many rifles and pistol have the fate of barrel or chamber erosion. I had a relatively short barrel life with a 220 Swift 30 years ago compared to some of my other rifles.
If you using R22, then you are getting into the super magnum loads. I shoot the 300 RUM, but I back the loads off to about 30-06 in power for shooting at the range. I shoot the RUM at full power for North American big game only these days. My load for the 300 RUM is a 92 grains of Norma Magnum powder pushing a Sierra 168 BTHP or a Barnes 168 TSX.
A comparable powder to R22 is Norma Magnum Rifle, which is hard to find, but I discovered it has less erosion characteristic than R22.
Hope this helps,
Jerry

My loads I shot today out of my 6x284 in relation to what loads are listed in the latest Sierra loading book are nearly 10% heavier with no pressure signs. Well wait the bolt did fly out the end of action but it missed me and I was able to hammer it back in the action. Other then that? But seriously those listed loads are so light with those slow burning powders that it could be a red flag in other direction. But Hey I guess not they wouldn't of printed them. Today's loads were the most accurate I've ever shot.

Ironworker,
Reloading data is based on the principle of not getting sued.

are you sure that the burning rate of the desired powders isnt a bit slow?

I don't know I'm just experimenting with all to find the best. With these slow burners I'm getting awesome accuracy but not the velocity yet. I think those fast burners produce pressure spike's easily. I want a full case of powder. Its just not fair.

you gota find that powder that fits your case ,if it is too slow you can cram it in there and never get the velocity you think you want.
you will find pretty good accuracy but you can shoot the same velocity with a slightly slower powder and still have a case full [90%+]
i have found going to a way too slow of a powder just fills the case fuller, and uses more then necessary.
for example i was using 38 gr of 4831 with a cast bullet load i could get beter velocity and better accuracy [at 100 yds and beyond] with 25 grains of 4895.
you just gotta find the balance, to much pressure to start or too much muzzle pressure.....which is worse????
they both affect the bullet negatively.

| I would call the powder manufacturer. They usually have software to help them predict internal balistics and therefore where to start.
