It really is the top powder I have discovered for velocity without any pressure signals in my 284 earn. Ought to be a great choice for the 6mm or 257R. Edited so as to add that this is While using the medium to heavier bullets - 140-a hundred and sixty gr.

I made use of a F1 Shooting Chrony to confirm the ft per next (Established a methods far from the muzzle @ thirty toes). I sighted in my scope while I used to be chronographing the cartridge masses.

The distance from chrono to muzzle is about ten ft. I did not have a tape evaluate but made use of steps so it absolutely was inside of 1-two ft at probably the most. I just forgot the tape measure is all. Need to I be putting it more than that? from . Click to broaden...

An extruded powder in Hodgdon’s Severe collection, it is most likely Safe and sound to mention much more big-sport animals are actually taken by handloaders with H4831 than another powder.

Alright, you may have gotten the speed that you choose to are searhing for but what about precision? You've not outlined how any of Individuals masses group? I personally would not be worried about speed if your groups appear like a shotgun blast at 100 yrds. You could in truth need to utilize a magnum primer particularly when you plan on utilizing these loads when the climate is cold ?

This website is utilizing a protection company hybrid 100v to protect itself from on the web attacks. The action you only done activated the safety Option. There are various steps which could set off this block which includes submitting a certain term or phrase, a SQL command or malformed data.

You claimed you do have a three groove, is it a benchmark barrel? I hear which the fellas with these barrels are acquiring in excess of published velocities.

Not expressing that powders isn't perhaps cranky in it, just that when You begin off with a notorious situation; it's possible not the powders fault.

I've run the loading sequence as a result of my head various moments, And that i have no excellent rationalization. 150grNBT

For H 4831 SC, this this Serious extruded powder is the exact ballistic duplicate of H4831. Physically, it has a shorter grain sizing which gained it the “SC” designation for “limited Minimize.” The shorter, a lot more compact kernels allow the powder to move from the powder measures extra efficiently, assisting to relieve the continuous slicing of granules.

Just keep in mind that no hybrid 100v powder matter what caliber you shoot at whichever velocity it is the bullet begins slowing down the precise quick that it leaves the barrel. Heck - if I could I might set my chrony out at a hundred-200 yds and genuinely get very good facts - but that's not practicle for a variety of good reasons.

Just go into a ballistic calculator and Participate in with the velocity right until you can get regardless of what fps your chrony is acquiring at the gap you established it at and hybrid 100v powder think about the muzzle velocity at position 0 yds.

AR-nine upper receivers, available through Arm or Ally, are crucial factors built to comprehensive the assembly of AR-9 pistols or rifles, known for their compatibility Using the 9mm caliber and high quality construction to ensure reliable performance.
