Well as the topic states, I think I have picked up a bullet that I want to try out but I can't seem to find the proper data for it. ( I know, I know I should of looked this up before buying a pack but it was an impulse buy while at Higginsons today ;))

I bought some Hornady Interlock (Model #3060) FP for my .308Win.
3060-01.jpg


Specs:
weight:170Grain
Ballistic Coefficient (G1) 0.189
Sectional Density 0.256
Bullet length 0.998''

So I have 3 manuals: Hornady 8th edition, Lyman (newest edition) and an older LEE reloading book. None have data for this load. The closest match is a bullet in the Lyman book @ 170grain but doesnt have the same dimensions ( it is another hunting bullet though). Ive also tried the Hornady website in their data section and they have data for 168gr then it jumps straight to 175 gr. So that is of no help neither. I looked around google but didnt find data similar enough to try out. The powder that my 700 likes and that I will keep using unless I start having issues is the IMR3031.

With my Match ammo ( no crimp) I am using a 168Gr bullet with 38.5Gr of IMR3031. Should I go with the load data of the 170Gr bullet in the Lyman book even though the bullet specs arent 100% the same and start lower that my non crimped match bullets, around the 28-29Gr mark (with a crimp) or should I keep searching until I find official load data? Would anyone on here have some of their own data for this specific bullet by any chance?

I have sent an email to Hornady but they seem to be slow to respond, and with the weekend around the corner I definitely dont expect a reply before monday or tuesday at the earliest.

Thanks a million for the help guys!
 
Any load data for a copper jacketed, lead core bullet of proper calibre of the same weight will work at the starting value. If the bullet has a cannalure, just seat to that depth. If not just follow the 100+ year old rule of thumb of seating the bullet to a minimum of one calibre deep or as much more as necessary for the cartridge to fit into the chamber, fit into the magazine, and feed properly.
 
Do you have any other powders?

For Rilfes, nope. Do you have another powder to suggest or comments ( good or bad) on the 3031 for this bullet type? The more info I can get, the more I can improve and eventually help others too.

The reason why you cant find load data for 308 is cause that bullet is designed for a 30-30......

I would choose load data for 175s from hornady. Start at the bottom and work up.

Good to know, Thanks! . My thought process was to get a hunting bullet with a weight close to my 168Gr Match bullets so with luck, I would have a bullet with similar shooting characteristics(for short hunting distances). never thought twice that 30-30's are .308 in diameter.Would they still be useable in my 308?

Never heard of this rule before but I will definitly remember it :)



So I guess I'll start out with the minimum loads from the Lyman book that has data for a 170Gr hunting bullet and go up from there. I'll also try to compare the load data with the 175gr one and see how it varies.

Thanks all!
 
170 and 168 are the same weight, so you can use your match load.

The OAL will be different. Seat dep enough to fir mag and be clear of the rifling. The cannalure will be in the wrong place for a 308. You don't need or a crimp.

Perfect, Ill do that . Thanks!

Reporting back this week with the results.
 
It is 30-30 data. However, it is for the exact bullet he has (Hornady #3060). Unfortunately, Hornady does not seem to list 308 Win data for it.

Edit: I've updated the post indicating the data is for 30-30 so there is no confusion

Posting data for a different calibre because it uses the same bullet is not only useless but it is very dangerous. Just delete it altogether. Or post a picture were it at least indicates it for 30-30. I don't get it!

Back in the 1950s when I first got my press an old timer told me "if you want a real deer stopper load 30/30 bullets in your 30/06" So I loaded 170 gr Hornady and used 180 30/06 data a few grs under Speer max.They shot paper OK,no problems.
I later loaded them in 308 Norma Magnum using the same approach and I got real pressure indications ,Soft lightly constructed bullet. Never did shoot a deer with this bullet. One must be careful!

You are right, George. That was definitely a potentially dangerous action on my part. Chart has been removed.
 
I'm just viewing my Hornady Handbook Volume II,
page 209 at the top is some information that resembles what
the OP is seeking.
They are listing the bullet as a 170 Grain Flat Point.
For liability issues, I won't post the info here.

No worries, I'm not crazy enough to try a load without exact reference or lots of research haha. At least I've learned that a 170Gr load in 308 is actually meant for 30-30.

Here is .307 data. As always start low and use at your own discretion.

Thanks! I will compare with the other info I've gathered and will try to contact Hornady later today! I will update you guys on what they say.

I will not agree to this statement.
 
Personally, I'd take the hit on the bullets, sell them to someone with a 30-30. Hornady Interbonds are reasonably priced and will be close to the Amaxs. Better yet is the Barnes TTSX 168gn or 175gn LRX, phenomenal hunting bullets and all copper (the grooves they cut not only reduces copper fouling by no overpressure problem like other manufacturer's copper/gilding metal type bullets). These bullets are almost as accurate as the Amax (very close if load tested correctly to ogive). imo
