![]() 3 grain until you hit pressure signs then back of. Why does ADI website list both 223 and 5.56 in the same page for reloading data: 223 and 5.56 are virtually identical the biggest difference between the two is that 5.56x45mm ammunition is loaded to a significantly higher pressure than the 223!Īny comments would be greatly appreciated! happy shooting! JustAnotherShooter Recruitĭeye243 wrote:A 223 with benchmark 2 powder will comfortably push a 55 grain pill 3350 feet per second I have literally burn 10 kilos of this powder over my shooting life I used to load 25.7 behind a 50g pill just a good accurate working load if I was you I would start it either 23.5 or at 24 and just keep going up in. If I start with 20grain i am afraid I could be undercharging my ammos and create a big pressure issue. I look at those projectiles above and they look completely different from the V-max.not too sure which to pick up. Wait a minute, didn't ADI said that those powders are equivalent? is V-max a jacked bullet?įor some reason does not show any load data for Hornady V-max 55grain so I have to choose other bullet type as:ĥ5 GR. 55grain jacked bullet IMR3031 powder to load 21.6 grain Send me a PM and I'll explain how to tune your gas block port for about any load you choose.- 55grain jacked bullet BENCHMARK powder to load 24 grain Since this isn't a 'Smith' forum, and I've been 'Warned' about giving 'Smith' information in the open forums, 'Felt Recoil' is a function of gas VOLUME hitting the bolt/carrier.Įven 'non-adjustable' AR style rifles can be tuned for a specific load pretty easily and cheaply. Varget can be a little heat sensitive when it gets real hot.īenchmark is EXPENSIVE around here, but its working really good for me so far. Varget starts to really shine around 65 grain bullets and up,Īlthough I had a Ruger M77 mkII that shot Varget and 55 grain bullets really good. The issue I had with Varget was when I loaded light weight bullets. Most people say it doesn't, which is why I picked it to try. ![]() When we get some warm/hot days I'll see if it has the same issues with temperature that 748 has or not. I haven't tried hot days yet with Benchmark,īut with 55-60 grain V-max bullets, about 26.5 grains is about as accurate as anything I've shot so far in 40+ years of reloading for. Varget got hard to find when everyone lost their minds. They would possibly work better in extreme cold? In your area with extreme cold and also hot summer temperature I'd consider using CCI 450, BR4, or CCI 41's as they are considered a magnum primer but only slightly warmer than others. Follow Hodgdon's data for H335 and you will be pleased with the results. Varget works well for heavier 69-77 match bullets. Benchmark, Varget, and 8208 work well BUT I still recommend H335 with 55 grain bullets. Takes a near max charge just to cycle the action of AR's Avoid 4198 unless it's the only powder you can find. The 4198 powders are the most troublesome powders in AR's with 55 gr. My 2 cents: Forget the IMR powders from IMR 4198 through IMR 4064 and H 4198, H380, or H414. I've loaded a lot of 748 though and would consider maximum to be 26.4 grains with 55 grain bullets. A max load worked up in cool temperatures will be over max in 95 degree summertime. Plus Win 748 is known to be temperature sensitive. Higher than 26 grains of Win 748 is required to equal 25 grains of H335. Win 748 is a good powder also but it takes more powder to equal H335 in velocity. Most popular powder on your list for 55 grain AR loads is H335 by a wide margin.
