Just wondering how much more capacity the 350 case has????

According to Ken howells book of case dimensions, the 284 is 92 gr of water, and the 350 is 104 gr of water, or roughly a 13-14% increase. - Dan

Thanks Dan!

Whoa! Sumpin's wrong here. The water weights Dan gives are far to great for the .284 or .350 cases.

Necked to the same bullet diameter, the .284 case is VERY slightly smaller than the .350 (6.5) Remington magnum case. I don't have the figures in front of me, but my guess is that the difference is on the order of 3-5% or so, depending on the manufacture of the case.

I think Howell is giving the gross water measurement, with no consideration for bullet seating. According to Barnes, the 284 has a 64.69 gr case capacity and the 350 has a 73.74 gr case capacity, which (although I'm doing the math in my head, and I'm not good at it) still is about a 13% increase, I believe. - Dan

I have a .35-.284. It is my understanding that it has 93% of the full case capacity of the .350 RM. This is from data obtained from "Load From A Disk".

I also have Ken Howell's book and he says that the water capacity numbers he gives represent the weight of a case as if it were a solid object of that shape and made of water. Of course that is not the same as the actual case capacity in grains of water filled to the case mouth.

I just sent you an e-mail regarding your 35-284.

Checked my NRA "Handloading" book, which lists case capacity, in grains of water, filled to the mouth, as: 284 = 66 grains; 350 RMag = 71 grains. Interestingly, they show the 6.5 RMag at 68 grains.

GonHuntin',
Go on over to the Medium Bore Rifles forum and read the string "Savage 99 Lever Guns". I described my .35-.284 there.
