Hi everyone,

Has anyone tried w-748 in their 7-08? How was accuracy, velocity consistency, etc.?

I'm thinking about giving it a try, but I've heard rumors that IMR 4064 is more consistent. Of course, I already have a can of w-748 and don't have any IMR 4064 ...

748 is a EXCELLENT powder for the 308based case .. varget is a slightly, and i meant SLIGHTLY better powder for 708 ..

the imr/winchester/hogdedon site have good info, IIRC.

Many metallic silhouette shooters used 748 in their 7/08 for the velocity consistency. We found no more than 15 FPS deviation using that powder. Important to use a magnum powder for my best results. It goes through a powder measure like crap through a goose, too! Speed was not as important as consistency since scopes were changed for each animal shot. I used 140 grain bullets for all but rams and 175s for the rams in a Rem 700 Varmint. Groups were always sub 1/2 inch.

With 748 I can duplicate factory velocities, but I get better accuracy and good velocity with a compressed load IMR4350 with 140gr bullets.

Thanks for the good info. I appreciate it.

My hunting load for 7mm08 Rem. is 40 grains of Winchester 748 and 139 grain Hornady Spire Point Interlock (not to be confused with the Hornady Interbond, which I have not tried). I couldn't tell you for sure what velocity is, never used a chronograph; but I do know that according a Sierra manual I browsed, it looks like velocity should be somewhere in the 2650ish range. But I have no way to back this up.

Accuracy is not outstanding, but decent: 1" at 100 yards, and better if I do my part.

Best wishes.

Last week I went to RL17 in my 7-08. It seems to be a great match. 2750fps with a 162 A Max.
Start out with bottom H4350 data.

W748 will give you velocity variance between summer & winter & it burns dirty. Very old 60 year old technology!

I recommend Varget, H4350 or VV N160.

I get exceptional accuracy with Varget and H-414 in my 7-08; Varget with 100 gn Sierra HP bullets, and H-414 with 140 gn Partitions.
