Well i made it out to do some shooting today and my loads were kinda all over the map (all post pics later). I think a large portion had to do with my shooting and not the gun, but some weird results none the less.

Is it possible for a 40 gr bullet to drift due to over rotation?

I found with almost no wind the bullet at 200 yrds was drifting 4" and at 300yrds it was off the papper say more like 10-12" all to the right.

(ill post pics with more detail tonight)

Load Data

223
40 gr Nosler BT
28gr BLC-2

@ 100 zero I would get 3 shots with great groupings then i would seem to get 2 flyers (i would say more than likely me)

AT 200rds is was droping around 2"
At 300rds it was droping around 14"


Anyone else have the LTR? with results

I went to the 40 gr because i want something scorching fast with as little drop as possible. however from the drop a 300 i dont think the load is screaming fast
 
How do you mean the bullet was drifting 4" at 200yds?

Compared to your 100m zero?
Was your POA and POI exactly the same at 100 or was your POI away from your POA by an inch or so?
Were you shooting over windflags, stuff can happen down range that you may or may not see from the firing point.
Is this a proven accurate load in your gun?
 
Well, the .40 grain Nosler has a low BC so it sheds quite abit of its velocity by the time you get out to 300yrds, and that is a long way for such a small bullet. At that range you will have better success with the 69-80 grainers.

Also, "almost no wind" will affect that 40gr bullet past about 150yrds (about what you experienced).
 
This is likely not much help but I shoot the 55 grn BTs in my 223 with 28 grain of BLC2. There are no signs of pressure. They group under 2.5 inches at 300. From 100 yard zero I click up 4.3 MOA.
 
That bullet is what I might shoot in my Hornet.

A 223 is very effective with a heavier bullet. Holds velocity better and has less wind drift.

I would say the 68 or 69 match bullet is the lightest to use and the 75 or 77 gr match hp would be about best.

i have shot the 223 with the 80 Sierra back to 1000 yards and found it drifted a bit less than a 308.
 
Your drift has next to nothing to do with rotation of the bullet. You are either shooting in more wind than you think, or you are already off at 100, and the extra range simply amplifies the issue. As some have mentioned, a heavier bullet is less susceptible to wind drift than are the light for diameter 40 grainers. Eagleye.
 
I have an ltr in 223, The barrel twist is 1-9 i would think the 40grain bullet are way to light. Mine loves 69gr sierras.

And as a fellow .223 LTR owner, I'd say you're "way too wrong". A 1/9" twist barrel is arguably one of the most versatile twist rates available in .224 cal. barrels.
 
Using tre Hornady balistic calculator on their site with the following data, I got this. 40 gr .224 at 3600 fps 100 yard zero. Drop is 2.2"at 200 and 9.5 at 300. Drift with only a 10 mph wind is 1.2" at 100, 5.1 at 200 and 12.6 at 300. Not that much different than what you saw.
 
Great posts, the bullet spin/drift theory was just a thought that come about in frustration. The LTR I have is 1-9 and does love the 69gr as 2bad4U2 mentioned. I come home and loaded a few more and went back out. At 100yrd I was getting The makings of a good group and then a FLYER or two off by say 2". ill be curios to load up some heavier lead and see if I can redeem myself. Last time i went out i was tossing 69gr down the tube in a mean wind and -15c with much better results. Ive never gone anything heavier than 69, so I may play around with a heavier bullet next and see what happens
 
Moose, I had an LTR that taught me the importance of a consistant hold. That rifle was more sensative to grip and cheek preassure than anything I'd shot before or since. Don't know what made it that way, but I had lots of groups w/ single flyers!
