I have at least one pound each of the fallowing handgun/rifle powders and would like to use possable/safe the one best suited for developing a reduced load for my 338 Winchester Magnum, please also include charge weights for use with bullet weights of: 200, 215, and 225grn.

<>N110
<>N120
<>H-322
<>SR-4759
<>IMR-4895

If none of these powders are usable in reduced loads, then would someone please suggest the powdwer, or powders best suited abd the min/max charge weight to use with 200, 210, and 225grn bullets?

I would like to do alot of practicing for an up coming elk hunt and would like to save wear and tear on both the rifle and myself, as well as cut down on barrel cooling time.

Thanks,
Arthur.

Arthur,

I have used Alliant Blue Dot and Vihta N110 with 180 and 200 grain bullets; both work fine with both bullet weigths, Blue Dot seems a little faster. SR4759 is also in that range, in tried it with different cartridges, very similar results even though it occupies more volume in the case which is good because double loads (biggest risk with fas powders for rifle cartridges!!) are easier to recognize.

After burning my last Blue Dot I standardized on N110 for all reduced rifle loads from the .222 to the 9.3x74, even the manufacturer recommends it for that purpose.

I worked up the loads after a QuickLoad calculation, you might be aware that these fast powders do NOT give low pressure loads, the spike is just shorter but can be as high.

35.0 gr SR-4759
Fed 210
Horn 200 gr FP (33 Win bullet)
2,200 fps (est.)
VG accuracy
Deer taken with load.

Only drawback was it didn't regulate to the same POI as my full-house 250 NPT load.

i recommend the varget start load & H4350 & H4895 start loads & 225gr.bullets,hope this helps for what you seek.

I was going to suggest DUK was your man for N110, but I see he piped in already.. he's the expert on that one...

my other choice after Blue Dot, would be the SR 4759... I use a lot of that also..

In my 338/06, I load that with a 200 grain bullet, and 35 grs of SR 4759.. for an MV of 2400 fps.. I hunt with that load a lot..

In the 338 Mag, I go with 40 grains of SR 4759, for the same MV of 2400 fps...

however if you are looking for light recoil loads, consider even loading 20 to 25 grains of SR 4759, with a large rifle primer.. no need for a Mag Primer...

velocity is lower, but I use lighter loads at 50 yds with the scope set on the lowest power, and use smaller targets...

the idea is to visually duplicate at 50 yds, what a target would look like at 100 yds, and then using the slower velocities, trajectory won't make a difference at 50 yds...

for field hunting with the 338 Mag, I normally use a charge of 60 grs of IMR4064, 4895, or RL 15.. largr rifle primer, and any bullet.. from 200 to 250 grains.

you give up about 100 fps in MV, but using about 15 grains or so less of powder than 'the standard' loads folks use with slower powders, the recoil is noticably much less...

good luck..

I still shoot .338 WM shells loaded with 36 grain Bue Dot and use that load also a lot for hunting in the woods. The biggest boar I shot if I remember it well was about 65 kg, gutted, perfect penetration, went 30 meters after being hit.
On roe deer the benefit is excelent performance with little meat wasted, that seems to go together with the low velocity.
As stated, I did not find a big difference in performance between Blue Dot, SR 4759 and Vihta N110, I shot all 3 of them through my .222 Rem plus some leftover H110 which is in the similar range.
Thus, I would presume that with any of the powders you mention you'll get satisfactory results. I try ty migrate to N110 because it's cheap, easily available here and I prefer to standardize to some basic powders like N110, N133, N140 and, not yet substituted by Vihta, RL19 which is in fact manufactured by Norma and also sold as 204.

Greatest of thanks to all who helped me out with their knowledgage. One last favor from DUK, what charge weight should I use for N110 and 200 grain bullets?

Thanks,
Arthur.

Arthur,

once I'm be back home next week I'll fire up QuickLoad to calculate some loads with a corresponding margin of safety.

Do you have a certain velocity in mind you plan to reach? What bullets do you use?

Regards.

DUK, thank you for the offer of help with my load development. The velocity Im looking for would be in the 2400fps range with Hornady 200 grain Interloks, as I have around 600 of them. This would be my 100yrd practice load. I am interested in using N-110 as i have four pounds of it I bought for use with my 10ML-II, but as fate would have it my 10ML-II MUCH prefers a diet of H-4198, or RL-10X.

FWIW, I shot 20 loads of 40grns of SR4759 with 200grn Interloks and this load gave me sub-MOA 100yrd performance. POI was around 1.25" low and 1.25" to the left at 100yrds, but oddly at 200 it increased to around 11" low and about 2.5" to the left. My rifle is sighted in at 2.75" high at 100 dead center with a load of 75.5grns of RL-19 and 225grn Accubonds. I was surprised at the substancial drop as I was lead to beleive this load has a velocity in the 2400fps range.

Thanks again DUK, as well as everyone else who helped me with thier knowledge,
Arthur

My current practice load for the 338WM is 38 grains of H4227 behind a 200 grains Interlock; Vo 2270 fps. No complaints about this load and all other loads I use H 4227 for, apart from the availability and price of Hodgdon powders here in Holland.
Just like DUK I plan to start using N110 for all of my reduced/practice loads, so I'm very pleased with is experiency on this subject.

BTW, I surely would welcome it if DUK could post more N110 loads here just like Seafire did with his Blue Dot loads. (for example loads for 85 grains Sierra in 6,5x57 and 100 grains Sierra in 7x64)

Before you proceed to work with handgun powders for rifles please keep in mind that these are NOT AT ALL low pressure loads, pressures are (for a shorter period of time) usually as hightor nearly as high as with regular, slower burning rifle powders. When a rifle powder continues to burn and produce gas, the faster N110 or Blue Dot is already completely consumed.

Even more important: Most of the times a double load would fit into the cartridge, since rifle cartridge cases have narrow rims, this is not as obvious to the eye than with large handgun cases. The resulting pressures would destroy your rifle and possibly hurt you, too. Thus, check each and every case before setting the bullet with a flash light. Then check again.

Now the facts: I tried N110 with 180 and 200 grain Ballistic Tip bullets, using 41 grain N110 for the former and 42,5 grain for the latter. I also tried 200 grain Speer SP with 42,4 grain N110, for this load the precision was really outstanding, calculated speed was 759 m/s with 3653 bar of pressure.

Regarding you request, 40 grain N110 will produce for a 600 mm barrel and a 200 grain Speer SP a velocity of 2405 fps with 47.089 psi pressure.

I always used regular LR primers, using little but fast powder in a large case does not worry me, after all, target loads for the .357 or the .45 LC also occupy very little volume in the case.

Looking at my notes, it seems that one grain variations have a relativly high impact on precision; thus, it is worth playing around a little if the desired precision is not reached with the first try.

Hello DUK,
Thanks a lot for your QL-calculations. They show that N110 is pretty similar to H4227; in both calibres my present H4227 load is almost identical to the suggested N110 load.
I will get myself some N110 and then I can start with testing/load developing.
Thanks again,
Gus
