Reloading Manuals (Maybe not all)

[Tommy Gun]

Based on the 3 load data manuals I use and with my other thread looking to create a new 168gr 308 load for my AR, I have a question.

When it comes to the popular calibers for AR type semiautos, why is service rifle data based on the archaic M1A? Why not have sections dedicated to AR type load data using carbine length gas system for .223 and maybe mid length gas system for 308. Is the M1A similar to the AR function? 99% of manuals are all bolt action data that is totally different parameters as a gas impingement system. I'm probably not looking at it correctly but all these companies have to know that AR is new standard.

And wtf, Hornady .223 service rifle has 68gr to 80gr projectiles. 62gr or 55gr makes more sense to have data for. Hell Hornady 10th Edition book doesn't even have their own 62gr FMJBT projectile in there. Just something that bothered me.

I'm sure gas length is not important but why not have info for 10" (Pistol length or subsonic) or 16" barrels as thats the standard for modern service rifles.

Although I would agree that AR15 might be the new standard the LR308 is probably not. Just anecdotally, I am the only one of my gun owning friends that has one and even at the range, it's all about the bolt gun for .308s.

It might also be that most reloaders are shooting bolt looking for that edge in accuracy whereas the gas gun guys are just buying in bulk. It has certainly been true before the pandemic that buying was more cost effective. But new editions are always coming out and the next one may have dedicated sections for gas guns. But then again, both Hodgdon and Alliant have a big reloading section online already.

I agree I'd like to see it too.

I have an LR308 so naturally it would be a welcome sight to see more loading data. I don't use many maximum loads very often and I do feel comfortable finding that sweat spot for my rifle that is accurate (for a gas gun <1MOA) and versatile for my plinking rounds. I don't feel the need to squeeze out that last bit of foot / second in any load. I just want good precision and lasting components in both brass and my rifle.

There are far more people using an M1A action in matches than AR10. There are more people loading for M1A than an AR10. The gas system really prefers certain loads so some manuals include M1A or M1 Garand loads.
