It's a amusing-hunting bullet using a rounded nose profile, however it shoots great and kills perfectly. Deer out to about one hundred fifty yards al went down immediately with rib-cage hits.
Using the smoother flow characteristics will come far more uniform charge weights, whilst the individual grains orient much more compactly, creating improved loading density.
Ballistically, this Excessive Extruded powder is the exact duplicate of H4831. Physically, it's a shorter grain measurement, consequently, the designation SC or shorter Minimize.

H4831 will do the job during the Swift although not authentic very well. You can hardly ever receive the pressures you may need for consistency With all the .223. 760, or H414 will likely be much better but for some explanation I ain't the greatest enthusiast of most ball powders.
The shorter, extra compact kernels allow the powder to movement with the powder actions far more effortlessly, assisting to ease the constant chopping of granules.
With the smoother flow traits comes additional uniform charge weights, when h4831sc powder the person grains orient much more compactly, producing improved loading density.
NBTs or Hornady VMax, but Use a constrained provide of Varget, and also a large amount extra offered H4831SC. I shoot 55 gr. loads almost completely, due to the fact that is certainly what the rifles shoot the best.
The Hodgdon gunpowder is environment recognized to presents the largest collection of excellent smokeless propellants for virtually any reloading software.
You might have to produce a number of additional posts for getting cleared to complete PM's. When you get to that status I'd publish inside the categorized reloading segment to find out if any person is near you for any trade.
Along with the 154 grain Hornady SP from the 280, H4831 gave me very good groups and great velocity, but Rottweil R905 features a significantly higher velocity and presents marginally superior accuracy. With Swift 150 grain Sciroccos during the 7mm RM, H4831SC gave great accuracy and velocity, but RL22 was marginally better. Therefore, in Every single of these instances I went with A different powder, but I would definitely hate to divest myself with the H4831.
Along with the smoother H4831 Powder move properties will come extra uniform demand weights, when the person grains orient far more compactly, generating greater loading density.
243, and many of the masses I have started with encompass, you guessed it, H-4831sc. This time I'm gonna shoot the IMR7828 loads first, accompanied by the W780 masses just H4831 Powder so there won't be any surprises when the H-4831sc hundreds demonstrate a shotgun pattern! Who knows, I just could possibly locate a use for it All things considered.
