I’m not devoted or bought in for that level of immersion but I acknowledge that a good sum of the community here has done the due diligence to find receipes that make 2590-2620 out of a 24” barrel a reality.
That said, I’m looking at two reloading sources Speer and Sierra and out of 28 listed loads , 2 are described as being able to hit the mark.
So from that perspective I feel as though the venture to see what one of these powders will do with a couple different 120 grain bullets has informational value and possible hunting applications.
I feel somewhat safer in following a book being that I am a casual Grendel user...
I'm with you Hunt, in that I'm a big fan of pressure tested data. In general, I'm leery of Speer's data, since most of their 120 gr loads are much lighter weight in grains and slower in velocity than other published data I've seen. Maybe it's because of their bullet, I don't know.
The data they have for PP-2000 is interesting, since it is so much higher than the other powders they tested. One thing I'd mention is that expecting 2620 fps from an 18" barrel with the Sierra 120 PH may not be what to look for. The difference in barrel lengths says you should be looking for about 2500 fps with an equivalent loading.
Looking forward to your results, I've been playing with PP-Varmint recently.
