Thread: Start and End load data for .308 Hornady A-Max 155gr

  1. #1

    Start and End load data for .308 Hornady A-Max 155gr

    I'm just wondering if anyone has a Hornady load manual to hand and would be kind enough to let me know what the start and end loads are for the A-Max 155gr in .308?

    I have the latest Speer manual, but haven't been able to find a copy of the Hornady load manual locally. QuickLOAD tells me that n135 is probably most suitable, but I'd like see what Hornady recommend and how much powder I should be starting with.

    Sorry not the latest as mine is a 7th edition book but here goes:-

    Hornady 155 grain A-max 0.308"

    Vhit N135 start= 35.8 grn Max = 42.3 grn

    Thanks for that, I really appreciate it.

    Lee's updated 2nd Edition of Modern Reloading has Vit 135 data for 155 grain bullets. So does the VV on-line loading manual.

    Do you feel that only Hornady can provide data for a 155 grain bullet???~Muir

    Hi Muir, I'm new to reloading and I was under the impression that it was correct practice to consult the load data for the manufacturer of the projectile you were using. I take it from your comments that this is not strictly the case?

    Ahhh nope tis not. I only answered the question asked as I had a Hornady book to hand. Mind you i also have Vhit 1st and 4th eds, Speer # 12,13 & 14, Norma No1 ed, Hodgdons 26th and a 2009 Annual manual, Richard Lees Modern relading plus a load of the free booklets.. I sort of accumulate them .

    Haha! I'll no doubt be adding to my 'collection' over time by the sounds of things. The Viht charts online don't mention Hornady projectiles and their data for Sierra HPBT 155gr and Lapua Scenar 155gr differ noticeably. The Hornady information you kindly provided me differs again, so I'm guessing it's safest to use the Hornady load data?

    Hi A J.

    In the Hornady 8th edition manual, N135 is not listed for .308 Win in the 150-155 grain bullet table. They have N140, and the data is as follows :-

    Start - 39.3 // MAX - 45.8

    My friend uses IMR 4895 in his .308 Win with 150 grain SST bullets and gets really excellent results for group size and velocity. The data range for that powder is :-

    Start - 37.7 // MAX - 46.4

    All the best.

    Neil.

    If you want to chase down the Hornady data, I guess is would be so. VV's site shows .6 grains difference in starting charge between Scenar and the Sierra offering in that weight. Since it is common practice to reduce starting charges 5% and work up, do you think it will matter??

    Lee's book only lists "155 grain Bullets" in their data fore 308. With few exceptions, physics are physics and the case, powder, and breech doesn't discern between bullet makes. It is the slight differences in bearing surface and metal hardness is part of what makes starting low and working up a good thing to do.

    I never load to bullet makers data, only the powder makers data. Internal ballistics is their business.~Muir

    Bit of a nubie question but would the a max ammo damage the meat a fair amount?? Being ballistic tip and what not.
