80 grains of triple 7 for me,sighted dead on @ 100 yards was only 4" low at 150 yards. Use 80 grains like i recommended and they will drop the deer.
I actually use these bullets and have for going on 6 years now, So i have quite a bit of experience with these bullets. I dont just use them once and try to make out that i know everything about them. I use these bullets because ive learned the right way to use them, they load easy and the accuracy i get is Superb.
A quote
"My brother hit a large buck on opening day in the front shoulder at 60 yards with a Platinum PB, 348g. "
There is no 348 grain platinum made to this day. Only a 348 grain copper series. Typo maybe?

Another Wrong....
"Oh, my brothers was the new Platimuum colored PBs, which is just the copper ones with a different polish, the lead mix is the same bullet, too hard, not soft and driving enough to hold togeter to kill."
To hard? Wrong, the lead is extremely soft and when i recover powerbelts from my range, i melt these down and mold Roundballs for my flintlock due to the very soft lead it offers.
More Wrong.....
"Amen, you made a perfect rib shot, the PBs don't disintegrate on rib shots, they disintegrate on bone shots in the shoulder. Therefore since nobody can guarantee their shot 100% into a larger deer one should logically either
1) only shoot small deer (<=80 lbs) ----you can break the bone on a small deer, they are fragile
2) shoot a better bullet that holds together in bone.

120-130lb mule deer doe with a 225 grain powerbelt, 80 grains triple 7, 80 yard shot.
Oh, And through the shoulder.
Now, While others prefer to use different bullets, which is their choice, I have to use a conical and my .45 shoots the powerbelts the best so ive shot hundreds of them, finding the right powder charge that offers the best performance on game. Now when i posted that i was going to use the 225 powerbelt on here, That started a conversation to use a 275 or 300 grainer minimum in my .45
After shooting many different loads,powder, penetration tests. I went out with a 225 grainer and 80 grains triple 7. We all know how the hunt went, because it is pictured in this post. And this hunt is one of the best hunts i have ever had.
Now, do you take advice to a person who actually uses them 99% of the time, Or take the advice of those who in some cases, have never even used a PB before or have Very little experience at shooting game with these projectiles? Ive spent a good amount of my money on these bullets,powder, caps to find the RIGHT load for these bullets.
Im just giving you the right advice on how to properly shoot these bullets, Thats all. After hundreds of rounds of powerbelts, I now know exactly how to use these bullets to get excellent performance.
Also, When you shoot a deer in the shoulder, All it hits is a very thin flexy roundish shaped disk. The actual shoulder bone is far forward and if you shoot at that on a broadside shot, you miss the vitals completely and end up taking out the windpipe, which in turn, requires a follow up shot to put it out of its misery. I found that out when i took a shot like that with a 385 grain great plains conical.
Again, Im just trying to help you out with using the powerbelt the proper way.
