Part 1 - Load Development | .338 Lapua Magnum - Berger Bullet - Vihtavuori N570

what's going on guys chris here with tactical outdoorsman welcome back to the channel and today we're going to be talking about 338 lapua magnum we're going to work up some loads so stick around [Music] all right guys welcome back so uh like i said uh we're going to be working up some loads for the 338 lapua magnum um i have a stealth evolution by savage chambered in 338 lapua magnum we did some testing with it back in 2018 and we're getting some pretty good results from some of the horny match ammunition and i'll leave a link to that somewhere there's an article that me my buddy frank did and you could read over that but what i wanted to do is i wanted to see if i could work up a nice accurate load for it and with that i reached out to the folks over at capstone and they were able to send me some components to help me do that so what they were able to send over is a hundred rounds of lapua breasts okay they sent over 100 rounds of this is the 300 grain boat tail 338 uh lapua magnum burger bullets and this one is the 250 grain boat tail uh burger bullet so we have another 100 rounds of that so we're gonna load up a few of the 300 and a few of the 250s um for those of you that don't know the the 250 grain is what we tested back in 2018 on the horn of the bullets and those performed pretty well we did about a i think it was a three i think a three and a half inch group at a thousand forty yards uh back in i think it was october or november 2018 with the hornady match but i want to see if i can do better than that with some hand loads so what we're going to be working with is the n570 vitavori powder also supplied by capstone and for primers i bought these these are just large magnum uh rifle primers from federal and to do the load development i decided to go with foster dies so i went with a full-length sizing die and i went with a bench rest cedar die so uh we're going to open these up i'll continue them i'll degrease them and put them back together for this process and we're going to be loading it on the horn to the single stage press okay so these are all the components that we're working with uh this is going to be a three-part video most likely uh first part is going to be me working up the loads here on the bench and just loading up a a sample set of the 300 grain and of the 250 grain uh second video we'll probably be doing some kind of a lather test at 100 or 200 yards which is the closest range to me that i have uh and then probably a third part to this down the road is going to be long range accuracy at the thousand-yard range which is a little bit further from me it's about a five-hour drive so it might take me a little bit of time to get that video up but i think i'm gonna have that as the third part to this so uh with that being said uh let's get into prepping the dies and getting the press set up to start working up some loads all right all right guys here we go uh so i'm gonna be starting from scratch so the first thing i'm gonna do is i'm going to disassemble my dies and i'm going to degrease them so let's pop these guys open get these boxes out of the way now this is pretty much the same thing i do with all my new dies i like to get all of the packing grease off of them all right all right here we go just gonna spray these down i'm using uh crc brake cleaner and it's just a parts cleaner no nothing special so just going to spray them down all right so i think we're good we are more or less dry on these dyes so i'm going to start reassembling them all right so i'm going to set the bullets either die aside for right now and i'm just going to work on getting the resizer die set up so we're going to go ahead run the ram up and we're gonna thread this down until we come into contact and then we're gonna back it off a little bit all right so we're in contact there we're going to back it off just a little bit all right all right uh so now that we got the die set up we're going to go ahead and we're just going to size some of this new brass it should be pretty consistent but i'm going to run it through here anyway just so they're all uniform okay now according to the trim two length on the vitivore website it says that the trim2 length is 2.714 inches or 69 millimeters so let's take a measurement here and see where we're at all right all right so we're at 2.714 so that's the trim two length so we're going to be good on this so let's go ahead uh we'll go through a few more all right i'm gonna go ahead and i'm going to size the rest of these and we'll be back in just a second so all right that's it we got the lube cleaned off and we're going to go ahead and move on to the next step all right guys we're back and it's the next day so it was getting pretty late i decided to just call it quits and get to bed but uh new day and i'm gonna go ahead and i'm gonna continue my breast prep and i'm gonna uh uniform the flash holes okay for the primers so i'm gonna go ahead and i'm gonna go through these 75 pieces and we'll be back with you in just a second after we're finished here okay we'll see you soon all right that's it for uniforming the flash holes and now we're going to go on to the next step i know i said i wasn't going to weigh the brass but i changed my mind i think i'm going to go ahead and weigh it and put it into batches so i'm going to go ahead and get started on that and after we do that we'll come back and we'll start priming all right so i just finished weighing the 75 pieces of brass and um they're all between 200 sorry 327 grains to 330 grains so i'm going to split them up into two groups i'm going to do the 327 and 328 grains in one group and the 329 and the 330 grain breasts in another group so that's how we're going to split them up i got them split on the table over here i'm not sure if you could see that on camera uh but we're going to go ahead and get on to the next step which is going to be priming and then after that we'll um charge all the cases and then we'll get to putting the bullets on all right so stick around all right so we're going to go ahead and start priming i'm going to be using the horn of the hand primer i could use the press but i kind of like this a little bit better it's a little bit quicker and we're gonna go ahead and we'll get to priming and then as soon as we're done we'll come back and then we'll start measuring some powder and dropping some charges all right we'll be right back all right guys so we're back here at the bench uh we're on the third day of this uh reloading project here um i know it's taking me a few days to do it but i only have a few small chunks of time to get this done in so spreading it out over a few days all right um so what i did is i separated my brass i don't know if you could see this here and what i'm doing is putting the charge weight on an index card here so the first uh the first three rounds here are going to be 89.7 these three will be 90.2 90.7 and so on uh same thing here so these three will be 92.2 and these three will be 94.7 okay and we'll just go down the list so that's how i'm gonna do this uh when i bought this case i didn't realize it but this is a uh a bullet down only case so i'm gonna have to charge them uh probably seat the bullet and put them into the case in one step instead of charging all of them and then uh seating a bullet and all of them but that's all right i have a new case on the way hopefully that'll be here for range time okay um if you see behind me i'm using the hornady electronic power drop it's warming up right now so we're going to give that a few minutes uh here's my second set of brass okay and here's the powder that we're going to use the vitavori n570 so we're going to be loading this up all right uh while this stuff is warming up i'm going to take my sizing dye out of here and i'm gonna get my seating die set up while i'm waiting for this powder drop to warm up okay so we'll be right back all right uh what's going on guys we're back so um set up to start loading i actually loaded two rounds already just to get things kind of squared away and dialed in so we got the 250 green hybrid otm tactical burger bullets here so those 250 greens we're going to load the first three rounds with 89.7 greens of the n570 be the blurry powder um and then we're going to move down the list for the different powder charges and get that all squared away so my cartridge overall length here at the at the end of this for this round of loadings for the 250 grain bullet is going to be 3.815 for the cartridge overall length the measurement that i took with the bullet touching the lens was measured at 3.855 so i'm taking .04 off of that uh just from the research i did that sounds like it's the the most accurate distance off the lens um so we'll go with that jump and for the overall length of 3.815 okay that's going to change obviously for the 300 grain and both of these lengths of the cartridge overall length are going to be longer than my magazine my magazine is only 3.773 inches so i'm not going to be able to load these into the magazine on the savage savage stealth evolution i'll have to just kind of load them right into the chambers which is no big deal i'm not going for speed i'm going for accuracy okay so i got the charge dropped here already for 89.7 grains so we'll get the funnel up on top of here and we'll start getting these loaded up okay okay and like i said i'm gonna be seating the bullets right after i charge them uh because the case i got uh the cartridges have to be bullet down so i have a new case coming where that's i can see them uh bullet facing up but for now i'm just going to seat these as i charge them okay i just want to check the length on this that's perfect okay so we're going to go ahead and continue loading the rest of these um my next charge is ready so i'm going to have at it i got 75 more to do and then when i'm done i'll be back all right guys uh that's it i got them all loaded up here so let me get a closer shot with the camera [Applause] all right so here is the 300 grain batch okay um we've got the 250 grain batch here okay all right uh so what i'm gonna do is i'm gonna do three shot groups um instead of doing five shot groups which is what i would normally do i just don't have enough bullets to do five shot groups on all of these so i'm going to run through from the minimum to the maximum power loads for both that 250 grain bullet and the 300 grain bullet for the 250 grain i'm going from 89.7 and i'm going all the way up to 96. grains of the n570 so i'm going in half green increments and then the 300 grain same thing half grain increments i'm going to be starting at 85.5 and going up to 90. okay so there's 10 loads in the 300 grain and there's 15 loads in the 250 green so we'll get them out we'll do three shot groups and then we'll see how they perform okay so we'll see in the next video okay guys [Music] you
