I thought I would give my update on the 110BA 338 LM. It is kind of a long post so hopefully that isn’t a bad thing. I have had mine about 6 months now and have put about 400 + rounds through it, 200 of those at a long range precision rifle course in North Carolina. To say the least it has been a very enlightening journey to try and learn this rifle and the caliber (my first big bore long rang file).
It has NightForce ATACR 5-25x mounted with NF rings (need EXTRA HIGH). Just a quick comment on the scope. IT IS AWESOME! It has the MIL-R reticle SFP and the glass is amazing and it has been the perfect complement to the rifle. Basically it has allowed me to focus on the rifle and not worry about the optics part. Pretty much everyone who has shot this rifle comments very positively on the glass.
Some general comments on the rifle. Yes it is left handed! It is the first and only bolt action left handed rifle that I have shot. Having used right handed bolts it took a little to get use to! Shooting opposite hand bolts isn’t as bad as some might think (or maybe I am just use to it). Having the left handed bolt though does seem to make follow up shots quicker. The bolt operates really well and I really never had an issue with feed. What I did have an issue with though was with the mag release. In the beginning it seemed in prone that the best way to support the rear of the rifle was to put a bean bag right behind the mag. It gave great support…but…yea…it would release the mag. Never did get that resolved so just went with the standard support at the butt. But here is the second issue and why that doesn’t work quite as nice. As another poster had pointed out (I did not make this original observation), the rifle mounted with the scope is top heavy. The result of that is, when mounted with the Harris Bipod which swivels it tends to swivel to one side or the other. As that poster pointed out, this can have an impact on accuracy. The solution he gave was to make sure you used a POD-Lock Swivel Lock on the Harris Bipod. I did that and it did make a big difference in stabilizing the rifle while shooting especially prone. Other than that everything else seem pretty tight with the rifle and it handles really well. I really have come to like how it feels.
And yes I enjoy shooting it very much. To me it seems to have very little recoil and I don’t notice the muzzle blast at all when shooting (not so for people not shooting and standing around where I am!). Shooting 200 rounds over 3 days at the Precision Rifle Class I had NO issues with my shoulder hurting or any issues with recoil. It was a non-issue. Interesting not so much with my partner who was shooting an unbraked 308. Half way thru the first day he needed some pretty serious shoulder padding (crumpled up T shirt under his shirt and jacked). Basically this is an incredible easy shooting gun for such a caliber. IT IS A PLEASURE AND A LOT OF FUN TO SHOOT.
So other observations. I didn’t do the barrel break in procedure thing (opps) and have found that the gun likes to be at least relatively clean and shoots best that way. At least a basic cleaning after each outing and something a little more extensive after 50-100 rounds or so. I definitely noticed groups opening up as the barrel got dirty, gave it a cleaning and got it back where it should be.
It does not like certain ammo. Tried the HSM Burger Trophy Gold and it did not like that AT ALL. It pretty much sprayed them all over the range. Didn’t like the 285 Hornday either. Aside from that though most stuff is pretty accurate. Most of my “testing” has been at 100-300 yrds and it is tuff to gauge which brand/bullet/load is better than any other. I have tried Black Hills in 250, 300; Lapua in 250, 300, HSM in 250 300 and to be honest at those ranges can’t really tell a difference (except the 300s definitely have a little more kick to them). They all seem to give 1 MOA or better at 200 and 300 yards and I just kind of settled on the HSM 250s at that seemed to intermittently give the best results (and a little cheaper), and this is what I went with for the Precision Rifle Class. Pic below is group at 200 yrds including CBS (squares are 1 inch)
I have tired hand loads with Lapua Scenars 250, 300s and SMK 250s and 300s. The table below gives some velocities for some of the different loads. For a lot of reasons I have decided to stick with the 250s for reloads and HSM 250 SMK for my factory stuff. Although I am going to try the 285 AMAX and see what that does.

At the class I was able to fire the rifle out to 1200 yards and it was a blast. The biggest observation is that at 1200 yards it was just starting to get into its own and it probably really isn’t worthwhile shooting it at anything less than 800 yrds as the 308s (everyone else in class was using that caliber) worked pretty darn well to that range (I got a much greater respect for the 308 after that class!). At 1000 and 1200 yards the 338 really started to excel. I was able to get dope data from 100 to 1200 yards with the HSM 250 grain SMK ammo (see table below).

What was also obvious at all ranges was the wind had much less effect and required less adjustment than the 308. With my partner calling the shots hits were routine out to 1200. Tried my 250 grain handloads the last five shots at 1200 yards and with the instructor calling them was 5/5 center mass on a metal silhouette , pretty much MOA or better at 1200 yards (with me shooting). The accuracy limit NOT being the gun.
Bottom line. Is this the perfect 338...well no...it is not a 1/4 MOA gun...but it is a less than 1 MOA gun and for under $2000 it is a pretty great investment and I will be looking to take it out past 1200 yards now. For anything 800 and under though I think I am going to really work with my new 308!
