Re: Technical question
Let's say you built two long range handguns with barrels from the same blank..... identical in every way except one.....the first handgun has a 14" barrel and the second has an 18" barrel......
DC---Lets look at something right here--4" length difference in barrels.
Then, let's say you built loads for each barrel identical in every way except one......
DC---The loads are the "same" in "BOTH/each" barrels.
The load for each barrel produced the same velocity in it's respective barrel......
DC-- If the "same" loads are used in BOTH length barrels, the longer barrel "should" produce "more" velocity.
For instance, if I shoot 100 grains of powder with a 200 gr bullet in one of my rifles and from a 30" barrel, the velocity "WILL" be slower then that "exact" same load in a 36" barrel. Same should hold true with your 4" longer barrel if you use the "SAME" load in each.
in other words, both pistols shot the same bullet at the same velocity.....
DC---If you shoot the "SAME load in each, the longer barrel should produce "MORE" velocity which would be a better choice for downrange impacts.
Now the question, assuming they both shot the same bullet at the same velocity.....would the added length of the second barrel have any effect on the trajectory of the bullet?
DC--- The added length should do better as per downrange impact and ballistics.
If in fact, the barrels are producing the exact "SAME" muzzle velocity, there would be NO difference to downrange impacts or drops.
Starting velocity is the key here. If both are the same to start with at point A, they will end up at Point B the same.
DC----I can relate this to the S&W 44Mags I had years ago.
One in a 4" and one in an 8". When I used the SAME load in both, the 8" barrel gave a bit more velocity which was a better hunting handgun for me.
Check your velocity over a good Chronograph and see what they are.
If the loads are the "SAME in both barrels, the longer one "should" give a higher velocity and would be a better choice for a hunting handgun.
You can get tooooooo long in barrel length to where there is more bullet drag produced and the added length of the barrel adds very little to the velocity.
I doubt if that's the case here.
Hope that helped.
