Ha! Fascinating place, but I went again and looked at the info. As I discussed in A few other opinions lately, I shot five distinct cartridges/masses above all three of Those people chronographs.
I then utilised the Prometheus Gen II Powder Scale to throw all charges. I've checked the Prometheus several situations on the high-conclusion Sartorius analytical scale, and every time it confirms what I previously know: the Prometheus is accurate all the way down to just one kernel of powder! The Prometheus isn’t low-cost (commences around $3,800), but in the event you reload just as much as I do, it may possibly conserve a ton of time, and will allow me to go to the range in place of sitting close to loading all day.
Speer Bullets, Federal Quality and CCI. The catalog states: “The powder charge weights detailed in our facts tables are maximum. For rifle and pistol loads, the utmost powder rates need to be reduced by 10 per cent to ascertain a minimal or beginning powder charge.”
There are statements made occasionally about cartridge styles currently being additional economical than Other individuals. For instance it is usually stated that the 6XC is a lot better than the 243Win since it can get to the exact same velocities with 7 grains fewer powder. Now this is genuine but IMO I think The rationale it is healthier is since the powder burn level of your powder getting used is better for that cartridge capacity. I am guaranteed Hodgdon could establish a powder exclusively for the 243Win that could make it execute even better in comparison to the 6XC mainly because loaded to exactly the same pressures the 243Win will melt away extra powder and thus have a greater velocity. The trick is getting The best powder for that cartridge ability, barrel length and bullet.
Many thanks for that screening, I use H-1000 a lot, I'm wondering if it is just as stable as it’s also a Hodgedon Serious powder. Wonderful report
I thought it was an excellent post. They went to some excellent duration (like renting a freezer truck) to test to receive it suitable. That makes it a lot more disheartening which the post is lacking the charts and photos. It appears like somebody copy-and-pasted it in from Yet another source and the photographs weren’t involved.
Hodgdon does not personal or work any smokeless powder factories. St. Marks, in FL, is the sole 1 nonetheless in the US and past I understood they did not make extruded powders. Furthermore, it wouldn't be Hodgdon's conclusion for them to make it should they did.
A alter in temperature can impact the trajectory or ‘flight route’ with the bullet in two very well-regarded methods:
Personally, I commonly want no less than ten shots above a chronograph right before I place any pounds around the stats (like regular, SD, ES) getting consultant for that number of ammo. I’ve noticed guys shoot five shot strings, but to me that isn’t enough. I’ve just observed way too huge of a variance amongst exactly what the stats say soon after five pictures and the things they inevitably say just after A further 5 photographs.
The intention of the subject exam was to quantify the temperature stability imr enduron powders of the popular Hodgdon H4350 and Varget powders and compare People to IMR’s new Enduron line of powders. To do that we cautiously measured muzzle velocities of meticulously loaded ammo about a big array of temperatures.
Truthfully, you positive may very well be proper about the MagnetoSpeed being more exact. It’s blind religion In either case, because I am able to’t seriously think about A cost-effective strategy to figure it out. If I had access to an entire-blown, Qualified doppler setup or maybe a commerical Oehler unit like what Sierra or a person takes advantage of, you could potentially probably determine it out.
That’s an excellent query, Kasper! From the barrel test I carried out a short while ago, I measured chamber temperatures above a twenty spherical rapid-fire string (all fired within 1 minute) plus a fifty spherical gradual-fire string (fired imr enduron powders more than 20 minutes). The temperatures I recorded weren’t as substantial as you may think they would are already. Even to the immediate-fire check, the highest chamber temperature I found was 149° F. Now semi-automatics would probably get Considerably better, but this was all finished for bolt-motion rifles and 20 rounds per minute is a pretty fast charge of fire.
Lots of attained shooters put a big emphasis on utilizing a temperature steady powder, but could we imr 7977 in stock as shooters have forgotten the necessity of a temperature secure primer
Yeah, I had been a huge lover of 8133 myself. It seriously sucks not owning it anymore. Most likely there will be considered a sufficiently big backlash that they'll discover Yet another place that could make if for them. Standard Dynamics may have a lock inside the recipe even though and It is feasible nobody else can make it.
