I see I had an error in my original Post. It's been corrected above, with the bolded word larger replacing the word 'smaller' in my originally posted answer. Sorry for the confusion.The larger the case capacity, the greater the MV, given equal pressures.
If you load a smaller capacity case to a higher pressure than a larger capacity case, of course the smaller capacity case could launch the bullet faster. But if both cases are loaded to equal pressures, the larger capacity case has a greater volume of gas to expel the bullet out the muzzle at a higher velocity.
Not a dumb question at all...This maybe a dumb question but, how does the less case capacity of the RWS brass effect muzzle velocity (ie: more or less velocity)?
