Sierra 125gr, 16" barrel vs 24" barrel with a variety of different powders.
ADI lists max charge as 50gr of 2208, which quickload predicts will go at 2869fps with 16" barrel. QL suggests same load will do 3152 with a 24" barrel
2206H, max charge listed as 49gr, which quickload predicsts will go at 2896fps. QL suggests same load will do 3186 with a 24" barrel
2219 max charge listed as 45gr, QL predicts 2851fps. QL suggests same load will do 3126 with a 24" barrel
2207 max charge = 39.5, QL predicts 2778fps. QL suggests same load will do 3023 with a 24" barrel
So we can conclude that QL predicts that the powder that will produce the most FPS from a long barrel, will also produce the most FPS in a short barrel for a given projectile weight.
I cant comment on if this would translate into real world or not but those are the predictions nonetheless.
I would think that real world FPS would be slightly higher than above as I kept the COAL the same as when I was messing with the 175gr load -- in reality the COAL would be shorter with the 125gr load, which will produce a bit more pressure and a bit more FPS. The general conclusion remains the same though.
