Hi there, I have a general question about over all length....
I have been using the following 9mm load for about a year now:
Powder: UNIQUE
Powder Wt: 4.6g
Bullet: LRN 125gr (Cast from W/W's with Lee Mold....)
Primer: Federal SP
OAL: 1.119 (I used this because it was the length of a WWB 9mm load and it was under the 1.169 that is shown on the Lee 9mm dies, it functions well and I stuck with it....)
There is no load data in the Lyman 49th manual for this particular projectile so I have been using the following load data as my basis for the above load:
Powder: UNIQUE
Powder Wt: Start-4.5 Max-5.0 (Because of the way this powder meters in my Lee Powder Measure I chose to use 4.6 as it is the 5cc Lee scoop)
Bullet: 125gr JHP
Primer: Federal SP
OAL: 1.075
Someone on here who I respect suggested that I use the load data for the 120gr LRN as the 5gr is negligible... So I used the following load as a basis:
Powder: UNIQUE
Powder Wt: Start-4.0 Max-5.0
Bullet: 120gr LRN
Primer: Federal SP
OAL: 1.065
From that load data I ended up with this:
Powder: UNIQUE
Powder Wt: 4.6g
Bullet: LRN 125gr (Cast from W/W's with Lee Mold....)
Primer: Federal SP
OAL: 1.075
So, to the point about the OAL.... Until I loaded up a batch of ammo based on the 120gr LRN from the lyman book I never gave the OAL much thought. All of my loads were 1.119
Well, today I brought two boxes... 50 of the 1.065 and 50 of the 1.119 I was shooting them all at 75 yards through a Hi Point 995 carbine...
The longer OAL outperformed the shorter OAL on every target. Why? How does OAL impact the performance? The gun functions the same with both loads... any thoughts?
Thanks and Happy Thanksgiving!
