[QUOTE="NZ Longranger, post: 992611, member: 14"] I do not agree with anything steeper than 35 degrees being more inaccurate. We have built many wildcats in a range of angles up to 50 degrees and have never seen any inaccuracy due to shoulder angle. The steeper angles give less brass flow and theoretically longer throat life. The shallower angles feed better but will grow in length more. The standard Ackley improved is 40 degrees, and I would suggest that is probably the one to go with as the best compromise. Just make sure you grab some Re33 as that's the powder that makes the 338AI hum! [/QUOTE]
