I heard that the new powerbelt platinum are a lot more accurate so I got some of them.they are aerotip platinum bullets with a grooved case (gasket.) they are 338 gr. I am going to try them tue.I will let everyone know how they do. triple seven, would you go down to the100 grs worth ofpellets or stick with 150 gr. thanks for everyones replies

The Platinums were degined-intended for magnum powder users - for those hunting larger game than deer. For 100 gr powder loads for deer or smaller, the regular Powerbelt ATs in 348 & 405HPs do real well (most-all cases). That new skirt on the Platinum is there to accomodate bullet speed and heat - when using magnum loads like 777.

If for instance at 100 grains, you are getting excellent groups with the old Powerbelts & not the new Platinum skirt, you can swap either-or skirt to either bullet. If you like the old skirt & want the Platinum bullet, it can be swapped around. You can also contact Powerbeltbullets.com by email or phone & inquire about purchasing bulk packs of skirts for either set-up. I would be interested to know their response to that. If you do contact them, please either send me a personal message with a copy & paste of what they said - or please post it here in public.... perhaps right here inside this thread.
