I've been trying to get these E-Tips to shoot and am having no luck. The Remington barrel on my 700 SPS .308 may only have so much potential but it does okay with lead core bullets. In the past I had some good luck with the E-Tips but not sure if that was a specific batch of bullets and or powder? Been running Winchester brass and Varget powder. Been shooting 45.5 grains of Varget which is below the mid load on the Hodgdon site but just looked at Nosler's online data and their mid charge of Varget for 150's is 44.5 gr. I did flatten a couple of primers so I'm going to drop the charge back down to 44.5 gr. My question is whether or not the 6 grooved 10" twist rifling of my barrel is not helping the 150 grain E-Tips? I'm thinking a 5R 12" or 13" twist might be a little easier on them. Not too worried about the twist but I am curious if the opposing even number of lands doesn't squeeze the solid core too much compared to a odd number of lands like a 5R has. I'm thiking of getting a 20" PacNor 5R 12" twist. Doubt I'll loose much velocity as I am only getting 2730 fps now out of the 24" barrel. I don't ever intend to shoot 180 grain or higher bullets that would require faster twist or slower powders. The .308 is really just my pig gun as I'll choose the 7mm Rem Mag for anything longer and bigger. The 150 grain E-Tips out of the 7 Mag shoot lights out. The 150 grain in the .308 is proving to be very finicky. Unfortunately in California the years of lead core hunting bullets are behind us. Here's a video of the E-Tips spraying all over the place. 4 MOA groups would not be an exageration. The Bergers shoot right at 1 MOA.
