I know that question wasn't directed at me, but I've used the light bullet rounds being called "silver tip" in several M91 and M91/30 rifles.
I don't find it to be any more accurate than other ammo, as long as everything is equal. A rifle with an excellent bore will usually shoot it all very well, unless the loads are deteriorating or there are other issues.
The one thing I do like about this ammo is the lower recoil levels and I suspect this is one reason why so many people like to shoot it and shoot it better than heavier fodder.
