I’ve got GRT and it doesn’t have A2495 powder data. Wondering if Quickload has it and if anyone can get me data for a load. I’ve got an optimized load with experience and data from GRT with hornady 75ELD and TAC powder but wanted to compare it to A2495.
Does Quickload have Accurate 2495 data for a .223 Remington

I don't have a load that's been worked up, but maybe this QL info might help give you and idea for a starting point:
That’s about what I’m looking for. My COL is 2.550. Any way you’ll run it with me COL? Thank you for running it already
Thank you for running this. I may be able to use the powder data and build a propellant chart in GRT.
I was able to input the data from the propellant and derive very similar pressure and velocity figures. I saved the powder profile and I’ll use it to test some loads. Thank you so much for providing the information.
I agree and with the loads I’m using now with TAC I believe I’m below 55000. I’m using the hornady 75ELD with the COL of 2.560 with 24.3 grains of TAC Lapua brass and CCI 450 primer. It’s running 2980 verified with Labradar chronograph Sunday.
I’m wondering if there’s more Accurate 2495 powder data than appears on that Quickload screen. I’m creating my own powder file with GRT but I am having trouble getting all the parameters to crossover between the two. The case fill % on GRT is off low and GRT seems to either call things differently or I’m just not smart enough to translate it.
Because of your LONG COAL ( 2.560' ), QL shows 24.3 gr of Ram-TAC around 48,000 psi !
But there are other parameters that can affect the chamber pressure. However, you're quite far from MAX load.
With a COAL of 2.260", QL shows 62,000 psi with 24.3 gr of Ram-TAC.
How long is your barrel ??? Cause with a 20" barrel and a COAL of 2.560" of TAC, Quickload shows 2,622 fps.
26" barrel QL shows 2,781 fps.
Thus there are lots more things at play than we can think of.

My barrel is 26 inches and the GRT software predicted 2900+ but not my true velocity of 2980. This is a benchrest rifle. The ballistic calculator predicts the correct elevation adjustment for the velocity and BC at 700 yards so I can believe that the velocity is correct.
All data including QL can be off a fair bit.
