H4831 will perform inside the Swift but not real nicely. you can expect to by no means receive the pressures you would like for regularity Together with the .223. 760, or H414 might be better but for some reason I ain't the largest fan of most ball powders.
Description H4831SC is definitely an Extreme extruded powder and the precise ballistic duplicate of H4831. Physically, it's got a shorter grain measurement which acquired it the “SC” designation for “brief Minimize.” The shorter, extra compact kernels allow the powder to flow throughout the powder steps much more efficiently, helping to relieve the frequent cutting of granules.
Velocity is 3025fps Based on drops. I don't use a chronograph as I haven't got any use for one particular. I bought my Ohler 35 quite a while ago. I'd never get it to match with what real drops were being. Also, I would from time to time locate a load with definitely little ED or SD and also have awful grouping at 800-one thousand yds. So now I get sighted in at 100, then shoot at five hundred to look for vertical. If it appears very good then I'll shift to 800-one thousand with regards to the cartridge and check for vertical all over again. If I see any, I am going to tweak my load up or down .
NBTs or Hornady VMax, but Have got a limited supply of Varget, and also a large amount more offered H4831SC. I shoot fifty five gr. loads Nearly completely, mainly because that may be exactly what the rifles shoot the most beneficial.
on the other hand, that additional horsepower commonly will come at the price of shorter accurate barrel lifestyle as opposed to lesser scenarios, and you’ll probable have to handle slightly extra recoil. during the precision rifle game, we’re all making trade-offs and trying to strike what we imagine is the correct harmony of ballistic efficiency, recoil, regularity, and barrel daily life. of course a great deal of shooters truly feel just like the 6mm Creedmoor was the right ticket!
I've observed the exact reverse to become legitimate in my gun. H4831SC was the slowest powder with a hundred and eighty g Accubonds. RL22 was a much faster and equally precise powder in my 300 gain Mag.
The PRS tracks how leading competitors spot in main rifle matches across the country. these are definitely the most important leagues of sniper-design and style competitions, with targets usually while in the 300-one thousand yard selection. This can be the third year we’ve gathered this data. for more information about the Precision Rifle collection and who these men are scroll to The underside of this post. lengthy-array Bullets in this article ...
And Of course, powders are once again staying challenging to occur by. It’s a seasonal issue that is available in cycles. I’ve heard rumor that some navy contract has triggered Retumbo, H1000, and RL-26 being close to unachievable for getting.
2-.5 grains and take a look at once again. Also tweak seating depth if needed. usually I can load right until I see some hefty stress then back off 2 grains and that will be genuinely near to in which I must be. I'm able to normally discover a load in much less then 20 rds. I don't really treatment exactly what the SD or ES is if it shoots in which I place it and it groups effectively. I have experienced two rifles a seven mag plus a three hundred mag that experienced solitary digit ES although the teams were being terrible at distance. So I stopped chasing figures and have become extra concerned with teams and finding a excellent node in my barrel. Not a favorite way of accomplishing points, but it really works for me.
“Casings with modest rifle primer pockets do get much more reloads than kinds with massive pockets. You can find additional steel throughout the pocket, so they hold up extended. There's a bonus to this for Competitors shooters. the main three or so periods a casing is fired the greater it varieties into the shooter’s chamber, which ends up in more steady muzzle velocities.
In my experience H4831 or 4831SC are infamous for Whatever you've professional. You'll get a load that shoots rather well with no trouble but it surely will not gentle up any chronographs.
I realize you will discover a few other powders which are purported to have related coatings, but I’m not acquainted more than enough with all of these to mention if that’s one of them. I checked out the data and it doesn’t look like any of these men are employing IMR 8208 XBR.
We observed greater precision with equally Hodgdon Severe powders though. nonetheless, When you've got many of this powder hanging out in your cupboard as well as a shiny new 7 PRC, I’m sure most folks to really make it hammer down.
I’m sure more info there’s a prosperity of info for 223 load data in other capturing disciplines like FTR but not sure how often you go to People functions. it'd be these that you choose to Obtain that data around an extended time frame by way of casual interactions and conversations with mates, loved ones and various shooters which has attained a substantial standard of precision Together with the caliber.
