It should be “too incredibly hot” or may well not meet up with your accuracy objective, but it really’s not going unsafe to your gun or else you.
Rationale #three: Precision. This is where Benchmark starts to run absent Using the title. Accurate 2230 and Accurate 2460 are arguably much better Velocity and Case fill than Benchmark or AR Comp, but They're just not as accurate as Benchmark inside our complete screening. AR Comp is "similar" but we think its just marginally less exact, and any time you take a look at dozens of back again to back, exact gun, exact load assessments on identical working day, you start to note it, a little. Benchmark is just leading major tier in Accuracy using fifty-sixty five grain bullets.
Compressed costs of slower-burn up-charge propellants are more suitable with loading heavier bullets. Obviously, Hodgdon presents load data For each and every bullet weight they’ve analyzed with all suitable propellants yielding Safe and sound and responsible ballistic data.
This chart supplies useful data for all hand-loaders. When doing load growth, and tests 1 powder as opposed to A further, it’s typically smart to pick propellants that share exactly the same relative burn up fee, as minimum To begin with.
Even so, my handloading mentor, John Redmon, who essentially bought me started in handloading the 223 Rem. a few years back extensive before I'd any desire in AR-15s, has reams of 223 Rem. data demonstrating how various the bulletseating depth improved accuracy in his bolt steps. I’ve found a lot of his targets that additional confirm The point that precision in bolt actions may be enhanced With this way.
Opposition shooters are aware that the bullet’s place while in the chamber throat/leade can noticeably impact accuracy. From time to time, I have experimented Benchmark Powder in stock with varying bulletseating depth to realize greater groups in my bolt actions, however the actually limited throat on the 223 Rem. cartridge situation seriously restrictions simply how much you can differ bulletseating depth, so I haven’t done Significantly of it.

Good day? That useless Heart group with the very first shot from the volley becoming out of main team continues to be the most effective team, definitely from all, and the other two groups are ideal in close proximity to MOA.
I'd about 250 items of Lake Town (LC) 5.fifty six NATO brass already prepped and able to load. Many opinions state that military services circumstances are heavier than professional brass. I’ve weighed numerous hundred parts getting several headstamps and concluded, generally, the real difference in ballistic Benchmark Powder overall performance is negligible.

That’s the key thing to consider when choosing suitable factors. They have to function the gun safely and securely and reliably prior to deciding to can start To guage their ballistic general performance downrange.
We need to get another thing straight. Establishing Protected and Benchmark Powder in stock trusted handloads inside a bolt-motion rifle is less complex than it's for a fuel-operated autoloader. Why? For the reason that burning propellant has just one goal inside a bolt gun—to propel the bullet out of the barrel.
