Levels of competition shooters understand that the bullet’s place in the chamber throat/leade can appreciably impact precision. At times, I have experimented with varying bulletseating depth to realize improved groups in my bolt steps, though the definitely limited throat of your 223 Rem. cartridge case severely limits the amount you may vary bulletseating depth, so I haven’t finished A great deal of it.
Knocked off the journal go over That will have stopped me lifeless right there. For stress I take a look at seriously flat primers, requires a good deal to essentially flatten them.
H322 and XBR are equally really temperature secure powders. They meter terrific outside of my Dillon powder measures and it simplifies what powders I top off on.
That is an older thread, you might not receive a reaction, and could be reviving an aged thread. Make sure you consider making a new thread.
My load with Hornady fifty five-gr bullets was wonderful, but his With all the Noslers (inside a Rem seven hundred VS) wasn't. Hot temps + a bullet that tends to build far more force + distinctive rifle. Backing off at least 0.five to 25.5 or fewer would clear up his strain problems. In the case of anyone applying Federal .223 Rem brass that's been noted for producing pressure troubles resulting from It truly is thicker walls and thinner World wide web area, a decreased load is undoubtedly proposed. This is why some posters have distinctive effects with loads that are just wonderful for Other individuals. Nearly all handloaders who may have no strategy for chronographing their function-ups for a technique for acquiring a manage on strain of their guns with their factors. When pressure indicators appear around the brass and/or primer, then sadly excessive pressure is now current. Keeping track of the chronograph common velocities allows you already know when predicted utmost velocity has actually been reached. In cases like this It could be in the region of 3107 fps for those who regular out all 5 sources. As a result backing off a tad will Ordinarily stay clear of this and is particularly using great perception. One great way of acquiring a good manage on what your boundaries need to be would be to average data from all of the resources you can obtain. In cases like this, averaging all five resources offers a median utmost demand fat of twenty five grains at 3107 fps. In case you were being to throw out the "odd" maximum charge bodyweight of Hornady plus the "odd" lower velocity of Sierra you would get this common: twenty five.five grains at 3134 fps - which I do think would be a bit additional real looking figures for barrels within the twenty-22" vary from what I have viewed. That is definitely why I like to refer to as several data sources as you can just before environment plans to get a load do the job-up. In addition, 1 should really exploration and see if the preferred factors can add to strain (Federal .223 brass, Nosler Ballistic Recommendations, M193 bullets and many others.) Naturally this discussion is not about getting your "precision node" but just demand/pressure/velocity aims or ceilings. Nonetheless in my case, precision looks to enhance with boosts in cost bodyweight when loading H-335. Get started loads like 23 to 25 grains are only so-so, but loads like twenty five.five are Excellent for me. I are convinced the bullet utilized will make a bigger variation than the cost body weight. *While some Take note that 26.0 grains is actually a "five.56 NATO-force" load - During this particular circumstance it is clear that real 5.56 NATO-force ammo - LC M193 truly is way hotter and 90 fps quicker On this particular AR15. This will only be recognized via the chronograph or simply a strain barrel.
Add to estimate Only show this consumer #four · Sep eight, 2016 Here's a url into a DuPont archive file that displays IMR powders and involves Remington bullets. It can be outdated data. Observe that the images in the powder are from the aged sq. cans.

Personally, my expertise and impression of The 2 powders has long been almost the other of yours. CFE 223 will conduct improved the lengthier your barrel is plus the heavier the bullet you utilize. My views are that CFE 223 is correct on the verge of being too gradual of the powder to even use in 223.

That’s not to mention it’s just as straightforward to things a seventy seven-grain bullet in to the heaviest situation you’re reloading atop a full cost of BL-C(2) as it's With all the lightest bit of brass while in the batch. Just that, in most apps, you won’t come across a substantial big difference than if you merely segregate your circumstances by headstamp.
I in fact Will not know any individual Individually that has expert substantial mad strain with it in .223 and .308 loads. That staying explained -I would prefer to use H335 or W748 for the same sort of load but occasionally they are not out there but BLC-(two) is. I think a Mod like this powder for this use.
Compressed rates of slower-melt away-rate propellants tend to be more appropriate with loading heavier bullets. Of course, Hodgdon presents load data for every bullet excess weight they’ve tested with all compatible propellants yielding Secure and trustworthy ballistic data.
I would like to attempt other powders. Regrettably, I've in no way noticed a can of CFE223 and it appears like it may be quite a while right before I'll. Thankfully, I even now have the most important Element of 8lbs. website of H335 left. At 25gr for every load, it'll still take a yr or two to utilize up.
The post factors out by case in point the error of employing load info for just one producer’s bullet on A different’s bullet of various building but a similar bodyweight. Being an apart, a regarded (never to me!) problem with H335 is disclosed.
