XXL Discussion Group

Hello Alex

https://hodgdonreloading.com/rldc/

This data lists all three versions of both 308 and 30-06. Reduced, commercial and military. Didn't see any 55gr bullets though. Maybe you meant 155gr. It's all there.

Both Hornady and Sierra Manuals have similar data. However you must buy there books.

There is several loads listed in the 8.0 Edition Western Loads for both 222 Rem and 556 Nato. Just look for the 62 MIL M855 listing for the desired powder. Here is a copy of that document:

Enjoy.

I would recommend using the OAL Trim dimension listed on the manufactures load data. Hornady uses 1.373"/1.383" as your min/max trim rates. The 240/300gr XTP have a COAL of 1.745". If at any time you are unsure of your COAL, start at the max of 1.765" and check chamber fit and function. To tight. Lower .010" (1.755") and check, Repeat if necessary. Try to use the recommended manufactures COAL for any bullet, ie, Barnes, Sierra, Speer, etc.

Yup, the steps below are perfect. The only thing I would change, personally, is I wouldn't add the water while the case is on the scale. Purely because an oopsie could result in water in the scale and electonics doesn't like that.

GoW, by the way is Grains of Water.

Oh wow - this is a topic that can be discussed endlessly and there is no wight or wrong ... the burn characteristics of a powder are determined by a number of factors:

• explosive heat (energy conversion potential )

• burn rate and function (functions are never linear - some start fast and then slow down ...) , which depends on the chemical composition and shape of the powder

• density and bulk density (if bulk density is high, you can fit more powder into the case, which converts to higher pressure and energy)

Some burn rate charts might take only one variable (i.e. initial burn rate) . Others take a weighted average (of explosive heat, initial burn rate, etc.) , some take empiric values of similar characteristics (i.e. weight of the charge for certain calibers). This leads to a different ranking and can be confusing.

This statement, "My (perhaps naive) understanding is that a faster burning powder is typically better for lighter bullets travelling at a higher velocity and slower burning powders better for heavier bullets - regardless of calibre," is not correct. The rule of thumb is that smaller calibers (smaller case capacities) made for shorter barrels use faster powder. The powder should fully convert before the bullet leaves the barrel. Otherwise, a too-low powder conversion creates massive muzzle flashes and noise. So typically, pistol and revolver calibers use fast-burning powders as well as military calibers (for economic reasons, they often have small brass and short barrels like .223 or .308).

The load tables on xxl - other than on other sources - also show the powder burn, fill rate, etc. This helps a lot to find a suitable substitute for anyones default powder that might not be available. It also often lists the recommended powders. Hope this clarifies and helps.

I did it with 338-06 Not 9,3x62, and there is an important difference in the base diameter. look below. My process Anneal the brass

Dull length sizing with my 338-06 die. Measure ALL brass and trim if necessary In My case I could use the load I use for hunting for fire forming. As the difference between a 30-06 and 338-06 is only the bullet diameter. I do not know if its the same with 9,3. And done, that was all there was to it. HOWEVER. the base diameter of the 9,3 is 12,1mm while a 30-06 is 12mm. This might result in some very "blown" out cases that might work but wont look nice. I found this thread from USA, that might be helpfull. https://www.canadiangunnutz.com/forum/threads/forming-9-3x62-from-30-06-brass.663917/

I agree with spricht Deutsh, but add that in most cases the trim to length is usually 0.010 shorter than the max. length. It is most important to maintain a uniform length for all your cases if you are crimping the bullet, especially if the bullet has a crimp groove. You do not need to worry as much if using a Lee Factory Crimp (LFC) die, because this crimps the bullet with horizontal pressure, and not at the end of the case. Not sure if the die is available in your round, but worth looking for. Enjoy days at the range.

I think XXL only loads to roughly 90% of max charge. Others might not. I find that BARNES max load data always is in the overpressure zone as an example. As other here says, load to your weapon, use puplic load data as guidelines.

I think the file name is the issue with the special character "_"

COL really means nothing because of the many different throat lengths in various guns. Always measure your distance to lands accurately for each different bullet you use. The Hornady base to ogive gauge gives you a good reference point

it has been added - you and everyone else can view the status transparently always on this page: https://www.xxlreloading.com/request-new-bullet-to-be-added

There is load data already for 9.5 x 55 : https://www.xxlreloading.com/calibers/9.5-x-66-se-v.-hofe

Thank you very much.

Thanks for the suggestion - caliber is added: https://www.xxlreloading.com/calibers/6.8-western

We have added load data for the bullet

we have added Hodgdon Superperformance
