Well i purchased 2 boxes of ppu 140 grain ammo to shoot in the gun I just got to see how it shot and also get some brass for reloading.(Was 13.99 a box at cabelas). Hodgan says 47 is start load and 50 is max compressed. I loaded 49.2 and cant even get the bullet in. It really doesnt fit until I go to 48 which enables me to get to the col needed. I called hodgan and they said yes that is the data but with remington brass. Could that really cause that big of a difference.
Yes different brands of cases will have different internal capacities, some more some less. This will cause loads to have different pressures as a result. One of the main reasons to keep your cases separated by brand.
Even if you could get all the 50grs of powder in the case your not really going to want to start there anyway. With the smaller internal capacity of your cases your likely going to be close to the pressures they got with their max load with what you already loaded. This is why you start low and work up. You may have done this but by your post you imply you started at a higher level. This may or may not be an issue, but from experience, it might give you a big surprise when you touch one off.
You will likely find that you can get just as accurate of a load by working up even using the lesser amount of powder. And if your pressure is running a bit higher your also likely to get close to the velocity your looking for with less of it. If it were me, I would simply start at the lower end and work up looking for accuracy over velocity, and try to hit a happy medium of the two. For hunting loads out to around 300yds anything accurate and running at least 2650 or so from the muzzle will do you well.
I shoot that same bullet in my 7x30 Waters Contender with only a 14" barrel and around 2250fps max velocity, and it is a tack driver out to 200yds. It will expand easily within these parameters and has dropped quite a few hogs. Like I mentioned concentrate on the accuracy, and let the rest take care of it's self.
