What does published BC's tell you?

It will come down to 1. BC and 2. Velocity you can drive it. High BC means nothing if you can't get it moving fast enough.

27" barrel is not helping you That and no mention of your twist rate.

The 285 gr flatline has the best bc but requires 9 twist while I only have 9.35.

The rest three bc in declining order is
256 gr flatline > 285 eldm > 300 gr Berger,
But the extra weight helps with windage,
So I am still not sure what is my best choice.

Wait for Hornady to come out with an A-TIP in 338 caliber.

I see all the mall ninja specials but you fail to mention the best ones on the market. LeHigh Defense 257gr @ .890 G1 and a 245gr @.896 G1



If it were me I'd be running the 257gr ELR match.

Be advised Lehigh has a habit of under rating their BC's. Actual down range velocity usually adds a few points to the BC.

Extra weight doesn't necessarily help with wind. and even if it does it's only a few percent within the same caliber and rough velocity. so you're talking a difference of a few inches at 1000 yards instead of say a foot or more reduction in wind drift.

Will try when it comes out. In the meanwhile will get something going. I am out of 338 ammo.

I am ignorant I have never heard of it.
Will take a look and read around.

Lehigh is an under dog in the ELR community. they don't have the following of places like cutting edge, Flatline etc. there are far to many guys in this game with more money than brains and buy stuff because applied ballistics said so.

I have personal experience with Lehigh and can say dollar for dollar they are the best on the market over all once you take into consideration design, price and most importantly availability. Lehigh is rarely out of stock.

Don't worry too much about plus or minus 20 points on a G1 bc or 10 points on a G7. You'll find out what the real number is when you shoot them. they will surprise you

Shoot the 256FL work the highest node you can extract, that groups great and has good SDs.

The 256 has a very small bearing surface so they tend to run faster when pushed hard than a similar bullet like a lapua 250gr.

My favorite load from a 28" 9 twist was H1000 95gr lapua brass at 3,000fps yet have run close to 100gr.. In my gun it was 1 raged hole @ 100 with tight SDs and lots of reliable hits well over your goal distance.

Based of your twist it sounds like you have a Savage. These have a real hard time extracting reloads on the hotter side especially something that is soft like Hornady, that will be your limiting factor, more so than your barrel length and twist.

Yep I bet the URSA guys will have some input,

Don't mind KC Stott OP. He can be grumpy SOB, but he knows a fair amount. I use the Lehigh Defense projectiles in my HD pistol ammo. So he may very well be right about that. Wait for Lynn Jr. to weigh in here.

You'll find that many of them don't bother with the .338 LM. With the advent of all the hot rodded 375's the 338LM has taken a back seat. Realistically the 338LM is a 1 mile gun and that's about it. Guys that are serious want more, A lot more and hence the popularity of the 375's and 416's not to mention the underdog 408.

My dislike of Flat line bullets comes directly from the price tag. This game is bad enough, but the cost of projectiles can be pretty frigg'n ridiculous.

As for being a grumpy SOB. I will admit that is the way I come off. But don't mistake grumpy for blunt truth.

Diver had some very good points too.

Maybe because you are posting at 3:50 a.m.? I know you get up pretty early, I'd be sounding grumpy unless I had my first cup of coffee too.
