I have most of the reloading equipment and now I'm ready fro powder,bullets and primers.
The rifle is a 1916 Spanish mauser in 7.62X51.For now that's the only rifle I'll be reloading for.I want a fairly light load for 100 yd range use.
I have a Chrony F-1 to measure performance.My neighbor has reloaded some brass for me with
IMR-4064 43gr 147gr W'chester @2645fps 41K cup
IMR-4064 45gr 110 Speer spire pt @ 2847fps 37K cup
The 1916 seems to like the heavier bullet.

I guess I'm asking:

Should I go with the IMR-4064?
What brand LR primers?
Stay with +or- 150gr bullet or try a heavier one?

I have Lyman and Lees reloading books.

That's a 1893 Model action which is not the strongest of Mauser actions.
I sure hope you will take this advice, have that rifle checked very carefully
by a qualified gunsmith before you begin reloading for it.

I know that is not what you want to hear but there is a significant safety risk if
you choose to ignore this recommendation.

It's been checked for headspace and I've already put about 100 rounds through it already.

After several years of powder hopping I ended up selecting IMR4895 as my goto powder for almost all major caliber reloads.

I also like CCI brand for the primers.

Having basically one powder for everything has opened up the storage in the powder locker and (mostly) eliminated the "experiment time" for new powder/loads. This allows more range time and accuracy drills as opposed to "reloading chores".

Having said that though, your interests may be somewhat different, after all, we all find different amusments.

And I do use other powders and primers, powders because 4895 does not work for everything (having one base type reduced the storage requirement for about 30 containers to 4 or 5) and primers because I have to go with what I can get (not so much these days because I (finally) did a "bulk buy" and will be set for some time).

YMMV

Thanks,I saw theIMR4895 in the Lyman load chart.I would like to keep the pressure lower than around 42K psi.for the M1916.
I think it's between 4064,BLc2 and 4895.I'm going to look in the Lyman and Lee charts for something to get me around
2,400 fps @42K with a +or- 150gr bullet through the short barrel..........

gremlin, read this http://www.6mmbr.com/308Win.html. With lighter bullets you'll probably do better with powders on the faster side that are suitable for 7.62x51Nato/.308 Win. Although it's kinda hard to make a bad shooting round in this cal. As was said before, watch your pressure with those old spanish Mausers.

I load a real sweet load (.308 Win.) for my youngsters to practice with. It shoots a 100gr short Jacket at 1500 f/s. If all your doing is shooting 100 yards you don't need anything more and I'm sure the pressure is low enough.

Something like this maybe just what your looking for. scroll down till you come to the 308 loads

http://www.imrpowder.com/PDF/Youth Loads.pdf

I looked it up and I'm not clear on something.The two loads below bring up a question.

168 GR. SIE HPBT IMR IMR 4064 .308" 2.800" 41.5 2518 43,800 PSI 45.9C 2766 58,800 PSI
168 GR. SIE HPBT Hodgdon BL-C(2) .308" 2.800" 44.0 2569 39,400 CUP 47.0 2754 50,200 CUP

One shows PSI and the other CUP.Is there a correlation between the two?Which is the higher reading?

IMR 4064 is as close to an all purpose powder for milsurp rifles as I can find. 7.62x51mm/.308Win., 8mm Mauser, 7mm Mauser, .30-06, .303 British, 7.5x55mm Swiss, 6.5mm Jap, 6.5 Carcano, 6.5 Greek Mannlicher, 6.5 Swede, 7.62x54R, .30-40Krag, 7.65x53mm Mauser, 7.7 Jap, 8mm Lebel, 7.5 French.

I'd stick with 4064, if you expand your reloading, using one powder for multiple cartridges makes stocking up easier.

As for primers, if prices are equal I like CCI, but I have had no problems with Winchester

BTW, feel free back off to 40gr with the 147gr bullet, velocity will still be in the neighborhood of 2400fps. Which is good enough for plinking at 100yds. However, I wouldn't drop below 38.5gr for fear of eratic pressures.

I saw the 4064 was 43,800 psi..and the BL-C2 was 39,400 CUP.That's two different standards.Which of these is the higher pressure?
I'd like to have a good understanding of the difference between the two.Anybody?

I use 2230 in my rifles for light target loads. It works great, and I use it because I have a big keg of it for my 223 efforts. By the third round of reloads I had my 1909 mauser matched to the sights at 100 yards (the 300 yard sights were dead on at 100 with the lighter load), and it is probably on par with a mild 30-30 for the power level. This worked so well I modified the same load slightly for my 308 with similar results, taming that rifle for short ranged fun.


I would use a lighter bullet (they are usually cheaper, and shoot flatter, and by and large better for paper for a few reasons) and start your load at about 50% of the starter load from your data, work on it from there. If you do not have data for the powder at hand, ask again? If the bullet is too light or too heavy it can be "wrong" for the rifling, so you may have to go a little heavier than the lowest for accuracy if you want high end target loads.
