Re: New Aluminum tipped Wildcat Bullet test results.....
There are at least three different 338 options right now. The ones i have on order are a heavy jacketed 265 gr version that is roughly 1.920" in length. A 300 gr SMK for comparision is 1.720" in length on average!!!!
I went with the lighter bullet option to start with so I could shoot them out of my 338 Allen Xpress, 338 Kahn and 338 Allen Magnum. This bullet will offer 100 to 150 fps more in velocity potential then the 300 gr SMK and I am predicting a BC in the 0.850 to 0.880 range compared to the SMK with its BC of around .78 to .8 depending on specific conditions.
There is also a 300 gr version which I have not tested but Richard tells me he is getting good reports from customers testing them. I believe he has gotten reports of a 4.5" and 3.5" group at 1000 yards with this bullet at velocities in the 2700 to 2850 fps range in 1-10 twist barrels. This bullet is very long, Right at 2.020" in length and about the max I feel a 1-10 will stabilize. I do not know what BC would be, best guess, around .9 to .92 I would imagine.
The last version is a 311 gr design that is 2.250" in length. I know for a fact that a 1-10 will not stabilize these as I have tried even at my 338 AM velocity levels. A 1-9 may well do it but a 1-8.5 may be a better choice.
Richard told me last night he has the ability to make up to a 400 gr Aluminum tipped 338 bullet!!!!! I would imagine this bullet would be WAY over 2.5" in length and I have no idea what the twist rate needed would be.
For the two lighter bullets, a 1-10 will work just fine in the two cartridge classes you ask about.
