I do know, from perusing load data tables and personal practical experience, that Hodgdon Varget is a very functional rifle powder. I believed It will be fascinating to document how properly it performs in the preferred rifle cartridges.
Appropriately, When you have a rifle in one of those calibers, you almost certainly don't need to have the others. I mentioned will need, but of course want is a special situation!
What I rediscovered was an posting by Lance Robson, titled Hodgdon's H4895, Quite possibly the most Functional Rifle Powder?. Inside the article, Robson notes that H4895 performs perfectly in a wide array of cartridges, furthermore it's got the exceptional property of staying suitable for constructing significantly diminished hundreds. I recalled studying this text someday previously, but its significance experienced slipped my intellect.
The FTX bullet / LVR powder mixture provides a lift into the downrange overall performance on the .thirty-thirty Winchester, most significantly in retained energy at MPBR. This is due to the higher ballistic coefficient in the FTX bullet.
The powder creating the top velocity is mentioned initially underneath Every single caliber. It occurs that Varget generates the highest MV of all powders mentioned within the Hodgdon reloading desk Along with the 55 grain Speer soft issue bullet.
Hodgdon CFE223 is a comparatively new powder and I haven't experimented with it within the .308 Gain. Since the table demonstrates, Varget and H4895 drop only incrementally wanting CFE223. Loading any of those powders with a hundred and fifty grain bullets provides seem effectiveness.
Head IMR 4895 over to and find the "Knowledge" tab, then select "H4895 Diminished Rifle Hundreds." Hodgdon invites you to contact them through phone or e-mail When you have more questions about lowered hundreds.
Varget and H4895 give muzzle velocities in just about 5 p.c of your IMR 4451 load. All a few hundreds are strong.
With Varget powder, the FTX bullet gets a fourteen property shorter MPBR and 8 % much less Power retention; with H4895, MPBR is 17 yards shorter with eleven p.c much less Power. These comparisons essentially show the outcome with the tuned LVR powder to the functionality in the 160 grain FTX bullet.
Take note the f.p.s. for every grain numbers, which clearly show that H4895 and Varget are the two significantly much more economical at producing velocity within the powder charge than is Superformance. That is a pattern that is certainly common from below onward.
Looking at the figures and ratios, I see no extraordinary distinctions concerning Varget and H4895 In this instance. Both equally are high doing hundreds in this cartridge/bullet mixture. IMR 4895 The MPBR figures point out that the fifty five grain, .223 Remington load is usually a 230 property varmint spherical.
Probably the most interesting detail to me is that the 7mm-08 performs so regularly with all a few on the powders detailed. This means a scenario capacity to bore sizing stability which makes it effortless to construct superior masses.
IMR 4831 powder yields muzzle velocity values above 10 percent larger than Varget and H4895. In reality, Varget and H4895 give the bottom MV values from the 13 powders listed to the .
It depends on whether one particular is loading only for max velocity, or IMR 4895 is at least fairly keen on cost economies from reloading, by producing a pound of powder go even more.
