Need a good load for m77 mark 2 7mm rem mag
- Thread starter bowboss

Welcome to the forum.
You have a technical information typo problem here. There is no 450 grain 7 mm Accubond bullet. Nosler makes 7 mm Accubond bullets in 140 and a 160 grains. From your description, I don't know which you are interested in.
As to what the rifle likes, that's going to be individual. I have a friend who succeeded in bedding a m.77 in 270 Win to shoot reasonably well, but know others who had trouble with the task. What you need to do is look for a load your particular gun likes. It may not be the same as the next m. 77 owner sees.

Nosler.com shows 4350 as producing the top velocity for that bullet. I am fond of RL 22,, but I and my friends use 160 grain Accubonds.
I finally got the 150gr. Accu-Bond LR to, well bond...
I was using Reloder 25, but accuracy was dismal.
Picked up some Reloder 26 for the fiance's 243 Win. Works well in the Rem Mag too.
I'm loading close to max load in the Alliant online manual, keeping the bullets to 0.005" from the lands.

My husband swears by IMR 4831 at 62 grains under a 140 or 150 grain bullet in his 7 mag. Remington 9.5 magnum primers. Hornady brass. Shoots on average of .245 in a 3 shot group. Bad days still sub 1/2 inch. Uses Reloader 22 for 160 grain and above. Coal at 3.290. Just fits the blind box mag. I think Nosler called for 61 grains as most accurate load but 62 was the sweet spot with no over pressure signs. 150 Nosler CT chrono on average 3250 fps. Hasn't hit anything that's ever took an extra step.
