I have heard follks say, they can get more Super Comp rounds in their magazines.
Do you find that is true?
I just had Starline send me some samples of 38 Super Comp and 38 Super TG(Todd Jarrett).

I loaded them with no primers or powder but seated the bullet my normal 38 super OAL
and I could not load any more with them than my normal Aguila brass.

My 170mm STI magazines all allow me 28 with the Dawson tool less basepad. I have not cut the springs to get additional rounds yet.

Other Shooter Comments:	Not that I am aware of , there is a mag that has a shorter taper going from the double stack to the single at the top of the mag and these are said to hold 2 more rounds , some may be cheating and adding a Dawson plus 2 base pad , which would make the big stick too long for legal competition, but ok on the shorter mags.
Other Shooter Comments:	Maximum capacity really depends on several factors combined: -internal tube dimensions -follower -Base pad -spring -rimless case The rimless case stack and feed better than the rimed cases, so over all it is an advantage, not a magic solve it all. A good mag should do 29, a great mag is 30.
Other Shooter Comments:	I can get one extra round in mags using Star line super comp brass, I seat my 124jhp rounds to 1.250 which means 28 rounds in my 170mm mags plus one in the tube for a total of 29.

	38 super Brass Resizing using the Lee die
Using 2 Armscor and 4 Starline brass from Robert, and the DAA 38 Super Case gauge
Using 2 Armscor and 4 Starline from Robert, and the Shockbottle CG38S-100 Super Case gauge which is the comp version plus my Aguila in the back.
Using the Lee Undersized Carbide Sizing Die 38 Super from Midway for $19.99 Note: not completely DOWN
Using the Lee Undersized Carbide Sizing Die 38 Super from Midway for $19.99 Note: Completely DOWN
Results are:Notice, my Aguila are Super +P not comp., in this gauge they do not go all the Way down, but see next slide with a non comp. gauge.
Results are: for Aguila 38 Super +P brass
Conclusions? Draw you own! The Lee Undersized Carbide Sizing Die 38 Super has been working for me for 3 years. I also use a 9mm and a 40 in my Dillon 650, quick change setups.
