Need a specific starting and max load for 7mm-08 load..

I have a couple of reloading manuals (Hornady and Speer)... but my friend recently got some Nosler 7mm, 140gr, Partition bullets... and he's set on using IMR4064 powder (he's got a lot of it)... can anyone take a peek in their Nosler manual and tell me if they list a starting / max load for this powder and bullet combo? It'd save us from buying a manual (he's only got a Sierra manual) for just 1 box of bullets he's got (someone gave them to him).

Thanks in advance!
 
Nosler's web-based reloading data runs IMR4895 at a range of 37.0 gr to 41.0 gr, from minimum to maximum. QuickLOAD says, at the same COL, 36.70 gr to 40.75 gr. of IMR4064 will produce the same pressures. You won't be able to see that .05 grain number on a standard scale, but using either 40.7 or 40.8 grains will be close enough. It will fill the case slightly better than IMR4895, but being a little fast for the cartridge, it will lose about 60 fps in muzzle velocity as compared to IMR4895. The deer won't notice the difference, but it's the reason you don't see manuals listing loads for that bullet and powder combination in that cartridge.
 
I'm not at home but do you have any other load data for 4064?

If you start at minimum, and work it, you should be fine.

Hodgdon website has a starting load of 38.0 and a max of 40.5gr. Not with a Nosler bullet, but like I said, start at Min and you'll be fine.

You need to clarify that a little. I have some starting 4064 load data for .30-06, but I wouldn't try it in the 7 mm-08. He would have to have starting data with that powder, in that round, with a same-length same-weight bullet just to be in the pressure ballpark. I would be better if the base was seated to the same depth in the case to be close to producing the same pressure. Even then, it has to be similar construction, and not a Barnes solid or some other more exotic construction.
 
Yeah, I saw the web reloading data, but it's pretty incomplete... I imagine the Nosler manual would list what I'm looking for... if anyone has one of those manuals, I'd be really grateful if they could look it up.

Unclenick, if you checked the Nosler manual, can you confirm that they don't list a load at all w/ 4064 (I understand your explanation, though).

Sir, with all respect...Well, No Crap.

I guess I didn't treat him as a complete, doesn't know anything newbie. I figured he knew that he couldn't look at the load data for a 30-06 and use it in the 7mm-08. That would be kind of dumb, the bullets aren't even the same size:rolleyes:.

If he were to look at the load data that is on the hodgdon website, its not a Barnes solid, its a soft point(tells me it's lead with a copper jacket).

So in essence, with the load data, for a 7mm-08, a 140gr bullet(not a Barnes Solid), with the powder he is using...he could...

Like others have said...find a load in another manual that uses the same bullet weight with 4064 and start with the minimum and you will be fine.

IMR 4064 is a great powder in the 7mm-08...I don't blame him for wanting to use it.

Any 140 grain bullet will be safe starting at 36 grains of IMR 4064...max will vary depending on the rifle being used. I have seen some max out at 41 grains and others that didn't get there until 43 grains.

If you have a chrono...stop around 2,750 fps, as that will be near max.

If that doesn't suit you...ask the question on the Nosler Reloading forum...if its in the Nosler manual, they'll share it with you.

In case you didn't follow Unclenick, he went to the Nosler Web Site data for load info.

They only list IMR4350, IMR4895, and VitVo N150 powders.

He then refernced the IMR4895 thru QuickLoad for a comprable load with IMR4064.
 
I am not telling you to use the load I did, (as always start at minimum and work up, beacause each rifle is different) but the last time I loaded for my 7MM08 Model 7 I was loading 44 grains of IMR4064, with a Sierria 140 GR. Boat Tail on top. It was a stout load for sure. The lite weight Model 7 had sharp recoil to it and the best I can remember the accuracy was pretty good. Its been probably 8 or 9 years ago that I was tinkering with the 7MM08. My 30.06 is my go to deer rifle right now. Trying to remember what manuals I looked at but I always look at atleast 2 or 3 of them to make sure there was not a misprint on one of them. I know according to the new Hodgon data that load is real hot. My Speer,Nosler and Hornady books are from the late 80's to early 90's. Thats where I would have got my data for that load. I don't generally hot rod my loads and it surprises me that according to the new Hodgdon data I have, the strating load for a 140 GR. Bullet in 7MM08 is 38.0 GRNS. (For IMR4064) and the max is 40.5 GRNS. Do you guys think that these companies have backed down on their loads these days? Here is another example: My Older Speer Reloading manual lists a 7MM08 load for a 130 grn. bullet for IMR4064 starting at 41 GRNS. and the max of 45 GRNS. Ok the new Hodgdon data I have lists a starting load of 39 GRNS. and a max load of 41.7 GRNS. using IMR4064 and a 130 GRN. bullet. I must add that since my Speer loading manual does not have a IMR4064 load for a 140 GRN. bullet I used the 130 GRN. bullet only as an example. I do know that there will be a slight difference in the load for a 130 GRN. bullet versus a 140 GRN. bullet. That might just be the proof that the older manuals did list hotter loads? What is your take on this you reloading guru guys.

Thanks for all the responses guys... I think I'll tell my buddy that 40.5 of 4064 is probably where his Max should be, and he should start low and work up (like 36 or 37).

Thanks again.
 
Imr 4064 is a good powder for that case size my 22-250,243,and 7mm08 all like it hodgens site list the max at 42 grains with a 139 grain bullet that is what i shoot in my savage axis with no signs of pressure, but every gun is different so you might want to start around 39 grains and work up slowly. I tried 4 different charge weights and the 42 grains was the sweet spot for my rifle and got me sub moa at 100 yards. Good luck.
 
Barnes manual #4 has a minimum of 40 grains and a maximum of 42.5 grains of IMR 4064 for their barnes 140 grain TSX BT, MRX BT and their BND SPIT bullets.
 
9 year old post. And you still don't need bullet specific data. You according to the weight, not who made the bullet.
Maybe that's how you do it, but as usual your wrong again, wouldn't hurt for you to educate yourself on a few topics before you reply.
Bullet shapes differ from one maker to the next, bearing surface's differ from one maker to the next,.
Get reliable information straight from bullet makers manual, it'll save time and body parts, as well as rifle actions...
