It looks like we could conclude this number of H4350 is measurably additional temperature secure when compared to the new IMR Enduron 4451. In fact, Hodgdon H4350 experienced about 50 percent the variance of almost every other powder tested. IMR 4166 carried out very similar to Hodgdon Varget, In relation to temperature balance.
Reloder 33’s burn level is a little bit much too sluggish for basic use within the 7mm Remington Magnum, however it fired Speer a hundred seventy five-grain Grand Slam bullets quicker than other powders and gave the smallest group.
Freezing a bullet shrinks it considerably. Heating it that A great deal expands it substantially also. Despite having friction Heating with the barrel the tension amongst The 2 will be noticeably different. A “fatter” bullet under-going a similar barrel to be a “skinnier” bullet is obviously going to transfer at diverse speeds… Powder asside.
There are statements created on occasion about cartridge patterns remaining additional economical than Some others. As an example it is often stated which the 6XC is much better than the 243Win as it can get to the identical velocities with 7 grains significantly less powder. Now This can be true but IMO I feel The rationale it is better is because the powder burn up amount of the powder being used is healthier for that cartridge ability. I am sure Hodgdon could acquire a powder completely for the 243Win that might help it become complete better yet compared to the 6XC since loaded to exactly the same pressures the 243Win will burn off a lot more powder and as a consequence have a higher velocity. The trick is getting The perfect powder for that cartridge potential, barrel duration and bullet.
Benchresters do load on the variety and match but in regards to powder costs the usually are not awfully appropriate ,most use volumetirc Harrells BR powder measure i could be suprised if they charge a lot better than +- 0.
I begun at 58gr and worked up to 60gr. Was not absolutely sure the flat based mostly Partition would create far more pressure as opposed to Hornady bullet so I ended there.
I've done several searches below looking for info on the 150gr Partition and IMR 7977 and arrived up vacant. I decided to do some experimenting alone and go according to what Hodgdon had shown.
Many thanks, R700. Feels like pretty much as good of an evidence as I’ve heard. Surely matches my experience. With a facet Take note, I do use H4350 in my 22″ 6.5 Creedmoor and I really like the final results I’m receiving. But I don’t question that I would have the ability to squeeze somewhat more muzzle velocity from A different powder. I am aware a great deal of guys chase that past small bit of muzzle velocity, but People 25 or 50 fps bumps have almost no effect on hit likelihood In regards to long range targets.
No less than for the powders tested the variation of the muzzle velocity SD with temperature was only some fps. Hence not variable for many, Otherwise all reasons. Always superior to show a potential variable into a constant. Completely understand your methodology imr 7977 in stock didn't permit taking pictures for precision.
I’ve been at matches exactly where you start off shooting in fifty° temperature inside the early morning, as well as the day heats up to Nearly ninety° by mid-afternoon. When you have temperature swings like that, the muzzle velocity within your bullet could maximize by fifty fps or even more … which can be adequate to entirely miss a concentrate on.
Hodgdon Varget – When you've got been to any rifle match and mentioned reloading, It could be tricky not to hear about Varget. Whilst you might not have observed this powder in person, as it appears to fly off the shelf more rapidly than every other powder … it does seriously exist! When Varget was very first launched, it quickly received acceptance among predator hunters and benchrest shooters capturing the 22-250 and 223 Remington.
My reply from Hodgdon. It at the very least confirms the discontinuation. I questioned as well if there was any probability they'd produce it all over again Later on. Definitely he didn't respond to imr enduron powders that issue. I will think that's a no then.
The solution is easy, the IMR Enduron powders attribute a inbuilt copper fouling eliminator, are insensitive to temperature extremes and therefore are composed of small sized grains for straightforward metering and specific loading density.
Truthfully, we just aren’t enthusiastic about that powder due to what we’ve expert with it when imr enduron powders it comes to temperature sensitivity.
