Hey, Clay. That’s a huge question to attempt to handle within the reviews, And that's why it took me a couple of days to compose a response. I’ll try out to help around I'm able to. If I have been just getting started, I’d concentrate much less on gear (over and above a able rifle setup like you have already got) plus more about your basic marksmanship and idea of very long-selection shooting and most effective procedures on employing your extensive array rifle.
Reloder 33’s burn up rate is somewhat far too gradual for common use from the 7mm Remington Magnum, nevertheless it fired Speer a hundred seventy five-grain Grand Slam bullets more quickly than other powders and gave the smallest group.
Sorry I didn't necessarily mean to suggest there is a thing Mistaken with IMR 7977. I'm only declaring watch out pinpointing a commencing load for it And do not foundation your commencing load on H1000.
You will find statements made every so often about cartridge models remaining far more economical than Other individuals. One example is it is commonly stated that the 6XC is much better than the 243Win because it can get to the identical velocities with seven grains considerably less powder. Now this is accurate but IMO I think the reason it is healthier is since the powder burn off price in the powder getting used is better for that cartridge capacity. I am positive Hodgdon could create a powder exclusively for the 243Win that might ensure it is execute a lot better than the 6XC mainly because loaded to the exact same pressures the 243Win will burn much more powder and for that reason have a better velocity. The trick is finding The best powder for that cartridge capacity, barrel duration and bullet.
Even so, within an engineering feeling the problem is whether the design/regulation is actually a ok approximation. Can it be match-for-intent? Will it generate predictions which are adequately exact. By way of example, the entire 6 DOF method of equations with the motion of a rotating, symmetrical ballistic projectile is a better approximation compared to the three DOF technique of equations although the 3 DOF system is adequately correct For several trajectory calculations. An interesting stage Considering that the bullet would've a higher diameter at higher temperature on account of thermal growth. But, as usually, the important problem would be the magnitude of your effect, Wouldn't it alter the muzzle velocity by one hundred fps, ten fps, one fps, 0.
You are clearly receiving fantastic velocity and precision. I'd concur that there is tiny reason to jettison what you have got for the more recent powder.
Usually do not endeavor any in the procedures or treatments shown or explained on IMR 7977 this Web site. All gunsmithing techniques needs to be performed by a professional and certified gunsmith at their own individual threat. Will not make an effort to mend or modify any firearms determined by info on this Web-site.

Many thanks, R700. Feels IMR 7977 like pretty much as good of a proof as I’ve listened to. Surely suits my encounter. Over a facet Be aware, I do use H4350 in my 22″ six.five Creedmoor and I love the outcomes I’m finding. But I don’t question that I'd be able to squeeze a bit more muzzle velocity from Yet another powder. I am aware a lot of guys chase that last very little bit of muzzle velocity, but Individuals 25 or 50 fps bumps have virtually no effect on hit chance With regards to very long array targets.
Personally, I normally want a minimum of 10 photographs over a chronograph before I place any excess weight about the stats (like average, SD, ES) getting representative for that number of ammo. I’ve noticed fellas shoot five shot strings, but to me that isn’t ample. I’ve just found also big of a variance concerning just what the stats say soon after five shots and what they finally say following One more five shots.
Loading density is perfect for magnums, properly filling the situation at optimum expenses, contributing to outstanding uniformity and accuracy. The 7mm Remington Magnum “never ever experienced it so very good”!
The results have been appealing, to convey the the very least! Each corporation’s claim their powders accomplish better than this experiment indicated … and that may be the case in different circumstances. I did notice both Hodgdon and IMR utilized Winchester primers in their tests. I chose CCI BR-four primers, because they give entire world-class normal deviations with my handloads, and because top shooters I have faith in have generally suggested both CCI or Federal.
So, this test definitely does deliver almost everything you may need for an answer. At this stage, you’ve obtained me wanting to know myself … so Enable’s stroll through it. Enable’s say it’s 65° File the day of your match, and in one circumstance you only shut the bolt on the spherical for around a next before you mail the shot … so there is basically no warmth transfer for the powder. In A different scenario, you loaded the spherical in a really incredibly hot chamber imr enduron powders and also the powder was heated to one hundred forty° File. To answer your concern about could it ruin any potential for a hit, Permit’s believe you might be applying one of several lesser performing powders In this particular test, IMR 4451.
So I loaded some 270WIN with IMR 7977 based upon a conservative H1000 charge and took them out and shot them.
Hey, I beloved the Oehler 35p. I had been it’s greatest supporter. But in my view, the day and age of the light-dependent chronograph are over … at the very least for me. The LabRadar is the final word solution in my opinion (at the least for shopper/prosumer options below $1k). It is possible to basically established it up and become all set to shoot in lower than 30 seconds, and I believe it’s one of the most precise machine. It doesn’t affect barrel harmonics similar to the MagnetoSpeed, so Meaning you could record muzzle velocities and shoot for teams or do load development concurrently.
