The 230 gr XTP has much worse field-testing history, than the 240 Mag, 250 regular or any of the 300 gr XTP diameter bullets.
You should do what I've done and so many others here...... park those 230 ACP bullets and buy something better...... at basically the same price. I have about 95 out of 100 in 230 gr. remaining in a shoebox.... gathering dust.
Send me $10 for shipping costs and you can have those remaining 230 gr. for free. Send me another $10 and I'll give you about 95 Speer Gold Dot 230s too.
