Then you'll find other methods that get started out by actually touching the lands w/ the beginning load. Seems like the above and H335 could lead to an ideal storm.
I looked at Hogdon's relative melt away rate chart & H335 seems to become quite a bit more quickly than CFE. Varget and BL-C2 seem like comparable to CFE with regard to burn off rate.
H322 and XBR are each pretty temperature secure powders. They meter good out of my Dillon powder actions and it simplifies what powders I refill on.
You ought to search his posts -- he purchases guns and runs them on the outer limitations, absolutely intent on destroying them all inside the seek for data and understanding.
It is usually advised to begin with “start” loads and perform up meticulously to maximum fees although cautiously looking ahead to signs of excess strain. The .308 Winchester can Make pressures instead rapidly, so this warning should not be taken evenly. A load that exhibits completely ordinary pressures, or pressures that happen to be in business suggestions, can jump swiftly above encouraged degrees with the addition of just one or two grains of powder (or by switching situation brands or simply ton numbers).
I've by no means had that materialize (cling fires) in everything .308 Earn sizing or underneath, with usual loads. Which means not minimized. That's strange that you should have it going on in a. 223 But like you I had a.similar practical experience with ball powder within a .280 Rem load. My Remington seven hundred Mountain Rifle would shoot it without any problems.
I generally look at at least two if no more data sources when beginning a load. Bullet maker and powder maker are the very first 2 I hit with rare exception.
I have also viewed powder ton figures differ more than enough to bump pressures to unwanted ranges. All over again, method optimum loads with caution. Additionally it is noteworthy when employing spherical powders not to more decrease the “start off” loads, or erratic ignition and Bizarre pressures can arise.
I have a Hornady Digital powder measure/scale I use for the challenging powders (like IMR4198 - my favourite .223 powder for smaller teams) that just will not throw constant fees via a powder evaluate.
H4350 - This Severe Extruded propellant is really a burning pace which has been recognised to shooters for many years. For the duration of that time, Hodgdon has modernized H4350 by shortening the grains for improved metering and making it insensitive to incredibly hot/chilly temperatures.

Insert to quotation Only clearly show this user #15 · Sep eight, 2016 I recall a newer technique of chasing ocw was loading yet one more previous max. If you do not have any pressure spikes, then it had been recommended to go yet another action to check out if you will get far more velocity for prolonged selection focusing on.
I'd like to try out other powders. Sadly, I have by no means noticed a can of CFE223 and it appears like it is going to be a long time prior to I'll. The good news is, I still have the most important Component of 8lbs. of H335 still left. At 25gr for every load, it'll nevertheless have a 12 months or two to work with up.
I am undecided that they are magnums, but I do know they may have thicker primer cup content. Somewhere all over below it had been just mentioned that they website are thicker to avoid any potential for Slamfires within a absolutely free float firing pin set up ( AR, and so forth) Kimber84
