What I rediscovered was an posting by Lance Robson, titled Hodgdon's H4895, Probably the most Flexible Rifle Powder?. Inside the article, Robson notes that H4895 performs well in a wide range of cartridges, furthermore it has the unique property of being suitable for building significantly reduced hundreds. I recalled examining this information someday before, but its significance had slipped my intellect.
The FTX bullet / LVR powder mix offers a boost to the downrange performance of your .thirty-30 Winchester, most significantly in retained Strength at MPBR. This is due to the upper ballistic coefficient on the FTX bullet.
The powder generating the best velocity is detailed initially below Just about every caliber. It happens that Varget generates the very best MV of all powders mentioned within the Hodgdon reloading desk With all the fifty five grain Speer tender level bullet.
Hodgdon CFE223 is a comparatively new powder And that i haven't attempted it while in the .308 Gain. As the table reveals, Varget and H4895 drop only incrementally in need of CFE223. Loading any of those powders with a hundred and fifty grain bullets gives audio general performance.
Go to and find the "Information" tab, then pick "H4895 Minimized Rifle Hundreds." Hodgdon invites you to Speak to them by means of phone or e-mail if you have added questions on minimized hundreds.
Additional telling is my working experience working with it in 8x57mm Mauser. I've a vintage Mauser for which I desired to function up some mild hundreds, but I'd problems with inconsistent efficiency when I went more than a few to 4 % below most hundreds for the primary three powders I attempted.
With Varget powder, the FTX bullet receives a 14 property shorter MPBR and eight percent much less Power retention; with H4895, MPBR is 17 yards shorter with eleven per cent much less Electrical power. These comparisons generally display the influence in the tuned LVR powder over the functionality of imr 4895 powder the one hundred sixty grain FTX bullet.
Be aware the f.p.s. for each grain figures, which clearly show that H4895 and Varget are both noticeably a lot more successful at creating velocity from the powder charge than is Superformance. It is a sample that may be frequent from below onward.
Looking at the numbers and ratios, I see no outstanding distinctions amongst Varget and H4895 In such cases. Both equally are superior accomplishing hundreds During this cartridge/bullet mix. The MPBR quantities point out which the fifty five grain, .223 Remington load can be a 230 garden varmint round.
I applied the on-line Hodgdon Reloading Knowledge Middle to obtain maximum powder rates and muzzle velocities for every load, and also other on-line equipment to determine other ballistic data.
IMR 4831 powder yields muzzle velocity values above 10 % larger than Varget and H4895. In reality, imr 4895 powder Varget and H4895 give the bottom MV values from the 13 powders listed for that .
It depends upon no matter if one is loading only for optimum velocity, or is no less than somewhat considering Charge economies from reloading, by making a pound imr 4895 for sale of powder go further more.
