The Remington cases Hodgdon used could be of lower capacity than the Norma Weatherby stuff.

Did you look at the data? The link you posted lists 80.3 grains of 7828 as max behind a 180 grain

Hogdon list a max load of IMR-7828 at 80.5 grains behind a 180 grain bullet in the 300 Weatherby. Hogdon lists 86.5 grains as max behind a 180 grain bullet in the 300 RUM http://www.hodgdonreloading.com/data/rifle Congratulations, you have proven that you too can read manufactures published load data. You can continue to post conflicting max load data from every powder and bullet manufacture but it does little to make your point or to contribute to this discussion. 11th Edition IMR load data states 86.0 Gr. My load is one half of one percent over published max. I can send you a copy of the data if you would like to read it yourself.

I don't know where you're reading JWP, but on page 51 of the link, the Weatherby carts are listed, and 86gr is a compressed max in Weatherby brass for the 300 and a 180 Partition.

The link you posted had the 300 Weatherby on page 53 and the 180 load is 80.3 grains

Pressure is velocity and you are over 300 Weatherby spec velocity by a considerable amount.

3240 with a 180 Partition, F215 primer. The speed is within Weatherby speed. Thanks

So if I am reading on pg 51 of the IMR manual, and see that I have a max charge of 86.0 gr IMR 7828, in Weatherby cases, at a seating depth of 3.56", then I could also seat the bullet out a little bit and have even more room. The speeds that Bullwhacker listed are spicy, but it seems like he is knowledgeable enough to understand everything involved. Some bunched up panties here.

No bunched up panties here. There are no free lunches, more than spec speed in a spec length barrel of 26" leads to higher than spec pressure. How do you account for the higher than spec speed without higher pressure? It is a very good bet that if spec velocity is reached with less powder than a Manuel lists that spec pressure has been reached in that particular rifle. It really is that simple.
A 10% increase in case capacity will yield a 2 1/2% increase in velocity at the same pressure.

I agree with you. It is all about the pressure. I'm sure the gun, the brass, and the shooter can take it though. I guess I just figured that Bullwhacker understood that 100fps over book means he is well above their pressure listing. I hope he does.

I guess I just figured that Bullwhacker understood that 100fps over book means he is well above their pressure listing. I hope he does. Agreed. The powder charge you claimed was false has been proven within specifications. The velocity you claimed was unobtainable has been proven accurate through a modest chronograph as well as ballistically over 900 yards. The pressure has been carefully monitored and checked to be within acceptable standards. Therefore why do you continue to challenge and claim false when your only point of reference is your limited knowledge in this particular situation? The thread inquired to the difference in two calibers in which I've had experience with over the past several years and I simply posted my results for reference. Can we call this adequately beat to death and move on?

The pressure has been monitored and checked how? You have a strain gauge ? How do you get the extra 100 FPS and stay with in spec pressure?

Some bunched up panties here. That very well could be where the additional 100fps is coming from,with near book loads.If you crowd the WBY freebore too much by seating the bullet out, the pressure rises fast. I've been around a bunch of 300WBY's, never seen one clock 3300+ without really standing on them.
