I would expect at 70 F that I’d be within 10 FPS of their claimed velocity. Hornady advertises 2675 FPS at the muzzle for their 224 Valkyrie 88 gr ELD Match factory ammunition, and I’m within about 25 FPS with my ammunition, and given the ambient (and ammunition) temperature of 31 F while shooting, it looks like I’ve pretty much matched the performance of their load. Not only are these groups looking good (I’ve read of a lot of trouble with 224 Valkyrie and heavy bullets) but the SD numbers look good as well: So I loaded up 10 rounds of 23.6 grains Varget with the Hornady 88 grain ELD-M bullets, and here’s what happened: My hopes were to bring out more of the potential of the 224 Valkyrie (velocity), and to perhaps get better groups as well. So I decided, even though the 10-shot load development data doesn’t support it, I would try the max charge. ![]() While the group sizes here are “reasonable” – the SD numbers didn’t look so good: You can see right away the “speed node” (stable velocity region) between 23.2 and 23.4 grains- so I loaded 15 rounds at 23.3 (right in the middle of the speed node) and shot for groups with the Magnetospeed V3 Chronograph recording velocities. ![]() Shooting these rounds over a chronograph produced the following: So I changed over to Varget (thanks to some input from the guys on the 224 Valkyrie Reloading Info Facebook Page), and found success! First up was to shoot a 10 shot load development string- with each charge weight weighed on a digital scale (throw + trickle) down to 0.1 grain accuracy.
