Alliant had a recall and replaced powder for anyone with it.

Remember, a max load is just that in a manual, most of the time they will be within safe pressure limits, however at times you can get a little hairy with them.

What type of guns are you loading it in? Are you checking the velocity? Who's brass are you using?

I AM LOADING IT IN A WEATHERBY ULTRA-LIGHTWEIGHT ACCUMARK CHAMBERED IN 7MM WEATHER MAG.I HAVE NOT CHECKED VELOCITY.I AM USING BOTH NORMA BRASS AND FEDERAL NICKLE PLATED.BY THE WAY,I CALLED ALLIANT AND TALKED WITH A TECHNITION ABOUT HEARING OF A BAD BATCH OF RL22.I HAVE 1 POUND OF THE LOT NUMBER I HAVE USED AND 3 POUNDS OF THE LOT NUMBER THAT WAS BAD UNOPENED.HE SAID BOTH LOT NUMBERS WERE WITHIN SAAMI STANDARDS BUT WERE A LITTLE HOTTER BY THEIRS.HE TOOK MY NAME AND ADDRESS AND SAID HE WOULD SHIP ME 4 POUNDS OF A NEW LOT # WITHIN A WEEK.I THINK THAT IS MIGHTY GOOD JUDGEMENT ON THEIR PART TO MAKE SURE THEIR CONSUMERS ARE SAFE AND HAPPY.DON'T YOU?I KNOW I WILL DO BUSINESS WITH THEM AGAIN!

I am glad they squared away the powder situation. They replaced 5 lbs for me, then I orderedd more that turned out to be the bad lot and they replaced that as well. Alliant is top notch in my book.

I am currently loading for 3 Weatherby Mark V's. It has been my experince that the action can take quite a bit.

Only once have I ever had trouble opening the bolt, flattened primers and the shiny brass. That was on my 340 Wby, I switch bullets and kept the rest of the load the same.

I had a couple theory's about what could be going on in your rifle, don't know how good they are though.

(1)Like Odessa said, if the bullet is touching the lands, in my Outfitter Custom 7mm Rem the throst is very, very short, more so then most bolt action rifles, and unlike the other two wby's I own. Having the round engage the rifling prematurely could contribute to increased pressures, maybe you could try to determine how far the bullet is from engaging the rifling.

(2)If you are using the Federal Nickel case it may (again this is a shot in the dark) have a smaller case capacity then the wby brass leading to the high pressure.

(3)I have noticed that if you get solvent into you chamber, the case seems to 'slip' more then normal and give somtimes incorrect readings of overpressure. (I noticed this on a friends 300 WSM)
