Just need confirmation that I am not going to hot with this powder.
Using IMR 4320 2.9 cc which I believe if my conversion is correct is around 40 grains with 150gr speer boat tail soft point.

Is this a safe load. I read the Lee manual that came with the die set and the manual stated that 41.5gr of IM 4320 is the Max load which runs the bullet at 2555fps.

I'm brand new to reloading so I just want to double chek with the experts

Thanks

Just a couple of tidbits of info. First regardless of what Richard Lee puts in print I would validate/cross reference it with other manuals. I have little.....actually no faith in the 'dipper method' so I would use a scale...then I know. You can find tons of good loading data online for free so you really aren't out any money to cross reference. Another thing that you will find with specific loading data....esspecially from forum friends...just because it is safe in their gun does not make it safe in yours....always check it against published data.
With that said .....if max load is 41.5 gr. then 40.0 gr. is probably a safe load. This however is not the method I would use to find out.

I worked up a deer-hunting load for my Model 99 in .300 Savage caliber that consistently put 3 shots into ¾ of an inch (or less) at 100 yards from a solid bench rest.

My test loads consisted of 4 different powders - IMR-3031, IMR-4064, IMR-4895 and Varget… 4 different standard (not “magnum”) large rifle primers - Winchesters, CCI, Remington and Federal… and 3 different brands of 150 grain, .308 caliber bullets - Hornadys, Sierras and Nosler Ballistic Tips… all loaded in once-fired Winchester brass.

I didn't try IMR4320 because I felt that powder was too "slow" to work well (accuracy and velocity) in the .300 Savage cartridge.

All bullets were seated to give the maximum overall length (with bullet) of 2.60 inches.

Working up SLOWLY once I was within 2.0 grains of the maximum load listed in my reloading manuals, I used an incremental increase 2/10ths of a grain of powder at a time.

My best (most accurate with the highest velocity) hunting load yielded a 3-shot group that had an average muzzle velocity of 2680 fps and measured .191 inches @ 50 yards (and averaged ¾ of an inch @ 100 yards) using a 150 grain Nosler Ballistic Tip, boat-tailed bullet in front of 41.5 grains (a MAXIMUM load) of IMR4895 sparked by a standard large rifle Winchester primer in Winchester cases. This load had a maximum velocity deviation of 19 fps (+9 fps / -10 fps).

My absolute BEST group @ 50 yards measured .112 inches and consisted of a 150 grain Nosler Ballistic Tip bullet with a muzzle velocity that averaged 2647 fps in front of 41.1 grains of IMR4895 sparked by a standard large rifle Winchester primer in Winchester cases. This load had a maximum velocity deviation of just 13 fps (+6 fps / -7 fps). I didn’t try shooting this group at 100 yards, but I’m sure it would yield an excellent group at that range.

All groups were fired using my 3x-9x by 40mm variable scope set on 9x at both 50 and 100 yards.

Incidentally, these groups were fired & these muzzle velocities attained from my 1953 “late EG” Savage Model 99 lever-action rifle with a 24-inch barrel using a rifle rest and sandbags off a very solid bench-rest on a 78ºF to an 85ºF day (11 AM ‘til 3:30 PM) with very little wind on June 24, 2002.

The final chronographed IMR4895 loads (averaging 2680 fps) consisting of 41.5 grains of IMR4895 were fired when the temperature was estimated to be 84ºF to 85ºF.

Earlier tests in May @ cooler temperatures (73ºF) yielded an average muzzle velocity of 2664 fps using 41.5 grains of IMR4895 with all other components the same as the above “hunting load”.

I hope this gives you some insight into what you might try in your rifle. Approach “maximum loads” with caution. The above load (41.5 grains) of IMR4895 is a very slightly “compressed load”.


Strength & Honor…

Thanks for the info fellas!
I am not too comfortable with the dipper method as it seems that the the powder may or may not be exact on each load. I am going to pick up some scales. Ron T I noticed you stated that IMR 4320 was slow for the .300 Save but when I looked up the Powder on the IMR website, they state " Short granulation, easy metering and perfect for the 223 Remington, 22-250 Remington, 250 Savage and other medium burn rate cartridges. It has long been a top choice for the vintage 300 Savage cartridge as well."
I know the velocity at max load 41.5 is 2555fps with IMR 4320 which is slower than your results with the 4895. is this what you are reffering too?

Thanks

Camper: My Lyman 45th Edition shows a factory duplication load for the 300 Savage using IMR4320 powdeer and the 150 gn bullet. The loading is 40 - 43.5 gns giving 2481 - 2672'/sec, with the later being a compressed load. The factory duplication load with this powder is 43.2 gns for 2659'/sec. HTH. Mikey.

there's only been a few gazillion rounds loaded using the little dippers. They, like the measures, are as accurate as the operator. I know several (at least three) folks that use the dippers rather than a measure in conjunction with a scale.
Few bench rest shooters use a scale while loading their ammo. Relying strictly on a measure or a dipper.

beemanbeme,

It just seems like there is more room for error regarding exact powder measurment with the dippers. I guess it just depends on who's holding on to the dipper. :)

Possibly the very worse thing a novice handloader could use would be a dipper method. If you are very familiar with powder and handling of powder ...fine go for it. I would again content that for a casual handloader with 'no experience' learning to use a scale is top priority. Richard Lee has the only handload data based on this method and all of it I have referenced was way unloaded ...quite possibly because he feared novice loaders would error using this method.

beemanbeme - you are comparing the skills of an accomplished shooter with many years experience.....who has shot a gazillion rounds to a beginner.
