Re: Nosler E-tip
It seems with non lead based bullets you get higher pressure with them, so Barnes and the new Hornady bullets have rings around them to help with pressure build up, meaning you can run close to the same powder charges as the same grain same design as a lead bullet. The E-tips will reach max pressure before the same sized lead bullet. You have a 150 grain lead and 150 grain e-tip you won't be able to load them to the same powder capacity I think nosler recommends a max close to 10% lower than a lead bullet of same size, meaning you will end up with a slower bullet than a lead accu bond or BT. If max is 10% lower and you want to run it 3-5% below max then your at a 15% lower charge than the lead counter part!
I have heard some guys say seat them some deeper, many say with long bullets doesn't make sense, but the guys that have shot them with good accuracy have found them to be better shooters when seated a little deeper instead of longer!
I'm going to try some of the new 90 grain 6mm just to see what I can accomplish with them. Hornady will have there offerings out soon, sadly nothing smaller than a .270 offered at this time but if you shoot bigger I would check out there offerings as well!
