Yep, Kirby is out of the shop for a bit. I'm sure he will get with you when he gets back.

.338 AM first time out.

I took my new .338 AM to my range for the first time today and WOW nice work Kirby. I don't think I really understood how much energy a 300 SMK at 3400fps had until today! I only loaded a few rounds to see how high I could go before pressure got to high. Took a couple shots to sight in and then the last 2 went under 1" at 425 yards and put about 5/8" holes through my AR400 target. My 338LM barely scratched this same target! Now my only problem is with the scope bottomed out I have to hold 10MOA under the target. Which means 10MOA under plus about 3.75 MOA that the bullet dropped at 425yrds puts me at about 13.75 moa when my scope is zeroed. That is about a 1000yrd zero. Is the only way to remedy this to order a 20 min base instead of my 40 min base?

wadec,

This confuses my brain: "Which means 10MOA under plus about 3.75 MOA that the bullet dropped at 425yrds puts me at about 13.75 moa when my scope is zeroed. That is about a 1000yrd zero." Is the only way to remedy this to order a 20 min base instead of my 40 min base?

I can't visualize whether the 3.75 is included in the 10 MOA or added to it as you indicate. I have a tough time getting my head around those kinds of things.

The 20 MOA base isn't the only way to correct this though it would be the better way.

You could do the ol' pop can shim under the front. Kirby would up-chuck his breakfast when he heard about it though.

I am using 10minutes under the target on my reticle and hitting where I am aiming however the bullet drops aprox 3.75 minutes so my actual point of aim is 13.75 minutes. Works fine but if I crank the scope to 42X the target wont even be in the field of view.

Re: Allen Mag Shooters Group

I am attempting to make my range .338 AM proof. Can any of you tell me what ranges these 3/8" steels will stop the 300smk at 3400fps? Ar500, Ar400, mild steel. I have access to all three but it will save me hauling alot of heavey targets around if i can get a starting point.

Re: Allen Mag Shooters Group

Have any of you tried the 300 gr berger in a .338 AM. With that BC at 3400fps it should retain alot of energy. Will they hold together on game? I have a bunch of SMK's to use up first but if they are promising I would like to try the Berger some day.
