Yeah, this undoubtedly displays why H4350 is sooooooo preferred Amongst the top rated shooters. I exploit a huge amount of it myself in my 6XC and 6.

I don’t think I recorded any temperatures higher than about a hundred and eighty degrees File. Is that this documented in any peer-reviewed location you could place to? You’re a sharp person, but I often attempt to deliver 3rd occasion support in my posts (like In this particular one particular I referenced Litz plus the analysis on Kestrel’s Site). The place am i able to go through more about the barrel’s job in this?

I don’t think staying off by 1-two degrees would have any measurable impact on strike chance, nonetheless it’s more with the twenty five+ degree alterations that could produce a miss. The lesson here is to simply not think the muzzle velocity you shot 60 degrees might be similar for 90 degrees. It just doesn’t perform that way. But sad to say, plenty of people don’t understand that and many ballistic calculators don’t assist you account for this type of variable.

94% of shooters finishing in the highest a hundred while in the Precision Rifle Series (PRS) elect to operate considered one of gun powders from your Hodgdon’s Extraordinary Number of powders, like H4350 and Varget (see the data). Even though These powders might not normally create the swiftest muzzle velocities, veteran shooters have realized to believe in that Extreme powders will deliver reliable muzzle velocities across virtually any environment.

Loading density is ideal for magnums, nicely filling the case at maximum prices, contributing to outstanding uniformity and accuracy. The 7mm Remington Magnum “in no way had it so very good”!

It’s attention-grabbing that at every match I’ve been much too, I’ve in no way heard of anyone applying Winchester primers. (Note: Hodgdon and IMR look like sister organizations of Winchester Powders, to ensure could have motivated their choice.)

Yeah, Rick it looks as imr 7977 in stock if we expect a whole lot alike! I do shoot at temperatures which might be unique than I zeroed, although I Test my zero rather usually … so I guess that limits that to a degree. I generally shoot at 55-95 levels ninety% of time, but After i’m searching that might be as little as 10 levels or at a summer months-time match, I would shoot in temps as high IMR 7977 as one hundred and five.

I did not get single digit SD’s with each IMR powders, but they ended up continue to respectable. I’m confident I could fine tune the hundreds for virtually any of those powders and reach great results.

I would say the temperature of my rifle and ammo are nearly always precisely the same, Except the rifle has heated up on a long string of fireplace (i.e. chamber is one hundred forty levels and also the ammo is ambient temperature). I'd agree that it seems like that will be the most common circumstance.

Bear in mind these have been all for that 22” barrel on our take a look at rifle, and also your mileage may well vary. We also just picked Protected masses for each powder, and didn’t do load progress to view what velocities for every powder could well be at max pressures.

The final results were fascinating, to mention the minimum! Equally enterprise’s assert their powders perform much better than this experiment indicated … and that would be the situation in different conditions. I did recognize equally Hodgdon and IMR utilized Winchester primers in their exams. I selected CCI BR-four primers, since they offer environment-course regular deviations with my handloads, and because top rated shooters I trust have often proposed both CCI or Federal.

Perfectly, Mike. It’s possibly not as big of a deal as you're thinking that. Think about the velocity dissimilarities while in the chart I posted within the reviews. That man chopped a barrel down one inch at any given time, and recorded muzzle velocities. Notice that a 22″ barrel was just fourteen fps slower than the usual 27″ barrel.

With that currently being explained, these new powders are anything Hodgdon statements IMR 7977 them being. Talk about staying unaffected by temperature, we were impressed. Look into the tabular success under for yourselves.

I was glad to determine you certified the final results to the particular a lot of powder utilised. These quantities will adjust from good deal to large amount for just about any provided powder.
