I have alot of H414 powder 140 grain accubonds left over from when I had my 7mm SAUM and Im wondering if I can combine the two for my sons 7mm-08 if not what would be a good deer/elk load. I have the Nosler fifth edition and it don't state a load for the AccuBond and H414. This is my second post and any advise would be great, thanks for the help.

Welcome to the forum.
RG #6 shows the following for the 7mm-08 and the 140 gr
H414 Start at 42.0 grs, Mid load is 44.0 grs and MAX load is 46.0 grs.
Remember to start low and work up.

My pleasure sir.
Let us know how the load development goes with the 7mm-08.

Jim,
Welcome to the forum. I should think that H414 would be a good powder with that bullet. As JD338 has mentioned, let us know how load development goes.

Didn't Bullet use that combo in his 7-08 to great success?

It seems odd that although 760 and H414 are supposed to be identical - and Hodgdon certainly lists loads for either interchangably - one can still find published data for different amounts of each for the same setups as far as rifle, bullet, case, primer, C.O.L. go. I mention this because the Hornady book for 7mm-08 is particularly wide spread between the two powders. Example:SJB358":3dnxg480 said:
154 gr. SST, 45.6 gr. of Win760 , 2700 fps /// 48.3 gr. H414 , 2800 fps. Data for their 139 gr. and 162 gr. show significant spreads between the two powders as well. Please note also that these loads are ABOVE what both Nosler and Quickload show for the 140 AB's. Personally, I think their W760 loads are more close to the real world - they must have had a weird batch of H414 when they were doing 7mm-08 data.
Please be especially careful working up loads for either one of these powders using the published data - it just seems there is more confusion than usual on these two.
