Since you're evaluating apples to oranges! This is why you might want to examine a reloading manual Before you begin or you're gonna damage oneself or someone else.
With close to max hundreds I constantly again it off when modifying to a fresh large amount of powder. A long time in the past there was communicate on the net of huge variation in RE19. My .338 Winchester at some time chrono graphed masses at less than max cost greater in velocity than exactly what the reserve had for max masses.
In any case, we have been at the array right now and with Blazer Brass 124 grain FMJ her PX4 cycled fantastically. We switched over to my 124 grain FMJ reloads that I labored up from Hodgdon's load information and we observed that she would get failures to feed. Nearly as Should the masses didn't have ample energy to cycle the slide every one of the way back again in order that it could strip a round and correctly load it.
Inside the grand plan of things, Alliant’s Bullseye has an ever-sodeserved standing of providing an extremely large degree of accuracy and uniformity of pressures and velocity in target hundreds. HP-38 has obtained an Similarly admirable name of providing superlative accuracy, As well as in contrast to Bullseye, by Hodgdon’s summation, HP-38 is a very adaptable propellant powder.
I’m sure my exams are usually not lab top quality but I’m also confident I recurring them more than enough occasions for your conclusions to generally be really worth thinking of. It absolutely was laborous dropping each powder in single method on the progressive press then weighing each, then repeating Just about every take a look at over a handbook fall measure to get weighed yet again on two unique scales and recorded. It absolutely was disappointing to search out my expense in three flake powders topic to issue and slows down my use of those powders. Even though I like Bullseye its array in some calibers is limited and reloading day a similar.
I am not debating that the bullets i am using may be a minimal tricky for std 38 special loads.what I'm getting a challenge with is data through the powder manufacterer that isn't precise.i dont Have a very chrony so i count on facts i obtain that shows a certain load recipe as well as the velocity it achieves. 158grn direct bullet above 3.7 grns velocity at 850fps.that to me looks like an honest load to start out a workup.however it doesnt get 850fps and from facts earlier mentioned is quite abit decrease.so i adopted accurate protocall and commenced reduce than hp-38 powder max and understanding they are going to generally be fired in my gp100 i thought i might have a good executing load.what i got was a anemic load that leaded my gun negative at twenty five rnds.
You will find there's 32 lb greatest of powder permitted for every HazMat cost, on the other hand, when you order powder and primers with each other below one HazMat charge, you might have 70 lb max per buy, of which no more than 32 lbs could be powder. Primers & powder cannot be returned. Look at nearby restrictions.
The end result for me would be that the good grained ball powder Bullseye meters suitable on the money and is also consistant though the three flake powders: 231, Blue Dot & Exceptional range via both equally steps with Distinctive getting the worst. About 5 ten drop tests Bullseye averaged proper on The cash with occasional although not Recurrent drops +- one/10of a grain while both 231 & Blue Dot averaged +- .
NOT Flake! This is the seriously flattened sperical powder! It is hp-38 powder possible to inform as the spheres were not similar size and if they went via roller to flatten, some when flatter than others, triggering different designs.
I do shoot mainly direct truncated cone bullets but absolutely have consumed copious quantities of FMJ along the best way. Right up until the powder shortage settles down we're all victims of taking pictures what we can find.
Insert to estimate Only present this user #twelve · Apr 21, 2023 Far adequate, and probably considerably safer. I do believe that these powders are precisely the same right now, but the companies addressed them distinctly diverse 40 moreover several years ago, so my feeling on this is they have not generally been the same, or there are tons out there which were a great deal diverse.
Having said that, you will find situations with lead bullet hundreds in revolvers the place you actually have to have increased pressure to pressure bullets to obturate (bump up in diameter from chamber stress). With numerous powder manufacturers making powder ... there are usually several powders which have the ideal burn up price for the software.
To even begin to know If they're the identical or close glimpse to wherever the powder was created around the bottle.
HP-38 is my go-to powder for your 9mm Luger cartridge. What it'd drop in a handful of ft for every second of velocity to other powders, it can make up for it in my pistols with much better accuracy.
