You want to look for 90% + fill capacity and 100% propellant burn, without exceeding max pressure...

Re: ok , need an expert guess...

I wouldn't quit on that load yet. Wait till some other guys chime in here. I have the latest version of QC which is V3.2. Mine is predicting 93 grains to be doing 65,555psi at 3130.
I do alot of work with Quick load and it can be really accurate except for two scenarios which come into play with your load. #1 quickload freaks out on long bullets and thinks they will make more pressure than they usually do. #2 quickload doesn't have any way for guessing if your gun has freebore which makes a big difference and I'll bet my hat that your gun has freebore.

You do need to chrono that load. I have done alot of work this winter with a 300 wby and have gotten great brass life out of hornady brass which is terribly soft with loads doing 3050 fps with the 200AB. I'm thinking that if you are around 3130 fps you aren't over max.
If you have a great shooter there and don't see any pressure signs I think you're doing fine.
Lets see if some guys chime in here that used that powder and load.

Re: ok , need an expert guess...

Each rifle is different.
Your worries now are that you are doing load development in the "winter" when it is "cold". You stand the risk of shooting that in warmer weather and having pressure go through the roof. Then you have a dangerous situation.
The program isn't fool proof but it gives you more information than you can get without hooking you rifle up to stuff that makes it look like it's going into open heart surgery.

Again, each rifle is different and you need to look at your brass, primer, check your bolt lift etc. for signs of pressure.

when i shot the other day, it was in the 70's, so it's not hot, but warmer than winter.

Re: ok , need an expert guess...

Well the published load by Hodgdon doing under 3000 fps has definately been "de-lawyerised". Heck there are tons of people out there safely getting 2950 out of 24" 300 win mags. There is no reason a 300 wby with 26" barrel shouldn't get 3050fps....and there is no reason you shouldn't be the next step up with the RUM up to the area of 3130-3150 fps. If people don't chime in here I'd check some other chat rooms and do a search. I think you are fine as long as you understand pressure signs. Another thing you could do is pick out 5 shells and shoot them hard and often and see if you get 5 reloads and still have tight prime pockets....if so I think your testing is done.
