I picked up a 50ct. box of one hundred sixty Nosler Accubonds, but I am hesitant to burn off the powder and projectiles on workup when all I have is 50 bullets. But I really need to find a bullet within the 160 class that my older rifle likes.
H4831 will get the job done within the Swift although not real well. You are going to under no circumstances have the pressures you will need for regularity Along with the .223. 760, or H414 is going to be improved but for some rationale I ain't the biggest fan of most ball powders.
4gr of H4831sc and Federal 215 primers. I discovered this combo provides .5MOA groups with velocity about 3020fps outside of a 26" barrel. I take advantage of this same powder in my 300wm capturing 180gr drugs, so It truly is good to obtain one particular powder for both.
Sweet!! I'll decide on some up and provides it a test. Thanks fellas, I enjoy it! I will Permit you to understand what I find out. I do have about a 50 percent pound of 4350 I am able to attempt that very first and find out what takes place.
My practical experience would be that the SC and SSC loaded to the identical weight as being the lengthy Slash exhibits a decreased velocity.
I know, tough moments. H4831SC will definitely work, I just failed to like the case density when loaded lengthy. I don't keep in mind powder demand off the highest of my head but I was launching a Berger 168gr VLD at three,000fps that's in which I usually purpose for being. Inside your situation employing what you may have (and what I should have finished) I'd get started with the tip of your bearing floor of the bullet suitable within the shoulder/neck junction, and flirt with extending seating depths from there after you look for a velocity node.
NBTs or Hornady VMax, but Possess a restricted source of Varget, in addition to a good deal much more available H4831SC. I shoot fifty five gr. loads Practically exclusively, because that is just what the rifles shoot the top.
Anyhow, I desired to give some 7828SC a attempt to minimize some of the compression. What a slip-up, I could not get this powder to shoot correctly or develop the velocities I get with normal 7828.
With the smoother move h4831 vs h4831sc features arrives much more uniform demand weights, even though the individual grains orient a lot more compactly, making better loading density.
The 55grs is all of that I shoot from my swift. Other manuals I feel that they have got slowed down the swift to indicate that their rifles are much better. It bug the hell outside of me. I do know much better. This is why I don't at any time throw out my more mature manuals. I do obtain new handbook on a regular basis to remain up on new chambers and there loading. I take advantage of this 39grs in summers @ a hundred+ degrees with none complications.
This is h4831 vs h4831sc often an older thread, you may not receive a reaction, and will be reviving an aged thread. Remember to take into consideration creating a new thread.
Indeed, You need to use the exact same load data for H4831 vs H4831SC, though the SC Variation may well help you get somewhat much more in circumstances in which you are maxing out circumstance volume With h4831sc load data all the normal powder prior to achieving force limitations.
Equally hold the Exact same melt away charge, shorter Minimize comes in helpful In case you are at max fill and not at force/velocity that you would like you can get additional shortcut within a case.
I found that my 7mag 160 partitions were being sub MOA with 4831sc with very low to min fees. I’m speaking 2700 (maybe 2800) fps, it absolutely was a lower 60s grain charge in a Norma circumstance. Not what I used to be searching for, but exact Even so.
