By the way, I think you need to come up with a good name for you 338/375 Long. Every good wildcat needs a name. :tup:

62 min of elevation! You need a bigger gun man. When you burn out that 338 barrel I need to get you set up with something bigger. :chuckle:been calling it 338/375xl

how many grains of powder with each trigger pull?83.5 gr h1000 at 20°F it’s shooting a 250gr Berger at 3015fps

Idk if I’m ready for the cost of .375 as much as I like to shoot
I would like to go with a bigger 338. But by then I may be over it and want the .416 :dunno:

It’s back up and running and I forgot how much I love that gun! 3050 fps is “cruising” speed with the 350 SMK in a 30” barrel and the 300s are at 3145 fps right now. One of these days, Biggerhammer will finish his 375 BME and I’ll get my reamers back. :chuckle:
Of course, I’ve got a 338/408 improved reamer sitting here too. I might even have a cheytac stock/action that I’d part with..... :stirthepot:

The GoPro is a HUGE help! At the ranges you're shooting you'll be able to take the shot, then watch the impact on your phone. I'd rather go out alone with my GoPro and spotter than I would with an actual person to spot for me!
I got one but no zoom ??? What am I doing wrong ? Spotter and iphone works ok at 1000 but gopro would be easier if I can figure out how to see soccerball sized rocks with it.

I mount it on the spotter with a phone scope adapter.

It can take a little work to get it dialed in and focused sometimes but it's worth the trouble.

I did put on spotter but must of done something wrong. Was in a rush to beat the morning wind, going to try again this afternoon.Maybe there’s a trick to it. I haven’t ever done it and don’t have a go pro but wanted to state the obvious anyways. :chuckle:

Oh I read that and had to stop and think did I ? Ha. I'm sure its a simple app tweak or something but I know my gopro doesn't have zoom but some app probably does.

Got a bunch of new spots scouted out. 1.4 miles, 1.65 miles and 1.8 miles. 37XC is ready to go and I’m just looking out the window cussing 🤬

Am I understanding you correct, it takes more powder to get the same speed? W/hbn
Post by: Magnum_Willys on March 18, 2020, 09:53:39 PM
Getting up in round count so decided to play with barrel a bit. Once I find max will see if it makes a difference. They say it makes first shot more consistent, less cleaning, lower sd, perhaps greater speed. Will find out. Certainly lowers pressure.

Found a nice spot today. Lil windy but can drive to both target and bench at 960 yards. 338-378 was dialed in - lower left on target. Was load developing Lapua with HBN. Holey cripes! Added 2 grains to get speed back up and looks like I need one or two more. That stuff is slick.HBN? And what is this slickery witchcraft, you speak of?

Hex Boron Nitride, it's a micro coating in which some people tumble bullets. The coating supposedly decreases copper fouling among other things.

Its like a fine white graphite. Tumble bullets with a 1/4 tsp and some steel shot and it plates them with a slick coating. Run two patches thru barrel soaked in it to pretreat ( one cup 99% alcohol to 1.5 tsp hbn)
It does dramatically reduce friction. Some love it some not worth it. I’m in testing stage ( something new to fight the blues) Costs $30 for lifetime supply.

Cold Bore shot - only got one try with Uncles 338-378.
Tried more of the HBN rounds today in 338 Lapua. Interesting, saw some very low es. But have to add a ton more powder to get speed back up and can't get the increase in velocity I was hoping for.
Has potential at slower speeds but too much recoil at 2850+. Scrapping HBN project on this rifle.

Regarding hbn test on Lapua. Cleaned barrel now won’t get speed back up. Wth?? Maybe time for that Proof barrel.

This pic just off the neck is strange. Carbon Ring ? Tried power scrubbing, maybe need to try more. Wouldn't think it would cause speed drop though.

I don't know what your 338-378 has on it for a barrel, but mine was just a standard factory gun and IMO the barrels they put on these big boys is way to small. If I would have kept mine, it would have been rebarreled with either a 9 or 10 twist Hart or Krieger in a Sendero contour. If I recall, the factory barrel on the Accumarks is only a #3 contour and it's fluted on top of them. I think the standard MkV even uses a smaller contour.
Post by: b23 on March 25, 2020, 05:54:58 PM
About 1000. Shoots fair still - hard to tell nodes with speed variation but less than 3" group at 300. All have been pushed pretty hard - Lapua brass 65k.
Lapua brass for a 338-378 ???
Post by: Magnum_Willys on March 25, 2020, 06:34:01 PM
The other is custom 338 Lapua with Carbon barrel that has recently gone to junk. Think Jasnt’s right - time for new barrel.
