The original question was about barrel lengths not action lengths.
YEA !bbl length was the org. ?
My dear friends...
The OP's original post can be paraphrased as:
(paraphrased)
...because of the extra powder (qualifier), does the long action benefit more from the extra barrel length
So the subject is action length and the qualifier is based on the assumption that long action length = extra powder. It was this invalid assumption that I addressed in my first post. The question of the validity of that assumption being resolved, and the fact that an action cannot receive a benefit understood, the OP could have rephrased his query if his curiosity wasn't satisfied. But let us return to the matter of the subject of the thread.
Note the title of this thread; long vs short. The only time the OP uses these terms is with regard to actions.
Note also, as previously stated, that the OP applies the "benefit" he speaks of but does not define, to the action.
Finally, the OP prefaces his question with:
I read about how barrel length effects bullet speed and was wondering if it effects long actions more or less than short actions
This indicates that he accepts as fact the statement that barrel length effects bullet speed. His concern seems to be with the effect a given barrel length on different action lengths has on "bullet speed." I grant you however, that it appears he makes the assumption in this phrase that barrel length DOES effect long actions and the post could be viewed as a compound guestion. Fortunately the second sentence narrows the scope of the question by starting with the OP's position: "I think," and he ends it with: "what do you think?"
Be that as it may, there can be little doubt that the object of the thread was action length, not barrel length.
Now, let's consider his question, in one of its many possible permutations, concerning the effect upon "bullet speed" of the action length in conjunction with a given barrel length. Since the OP didn't include parameters in his post certain assumptions must be made. As an example, let us say I have a 22" barrel on a short action that gives me 2700 fps with my preferred load; I want to use that load only; I also want a 20" barrel. His question then ends up being: can I cut my short actioned rifle's 22" barrel to 20" and install it on a long action, add extra powder to the cartridge it is chambered for and expect to keep my 2700 fps?
This example was the basis for my suggestions, express or implied, to the OP that he quit "kissing the wrong end of that sheep," forget action length with regard to velocity (if indeed his question concerned velocity), consider the performance of specific cartridges with regard to the velocity/barrel length question and handload that cartridge to the performance level he desires; staying within published limits.
Of course, I could have just left it with ... say what!?
