.338LM - .50 Cal

Re: Loads for .338LM

Sako TRG-42, 27 1/8", 1:12" twist.

Lapua Brass neck sized with .365 TiNi Redding bushing.

Fed 215M primer.

Hodgdon 4831sc @ 85.5-87.0 grains.

Lapua 250gr Scenar or SMK 250gr seated to ~3.650". Mag. safe.

~2775-2850fps @ 80*/sea level

0-750 yards ~.75 MOA

This is a bit milder than factory loads for the 250s at ~2950, but works well at short to medium distances and is a bit easier on the gun and a bit cheaper to load.

Re: Loads for .338LM

Lapua DID have a different brass base in use for their 338LM than what CIP uses. Today they are the same as everybody else.

I thought it was funny when they explained to me that their 338 LAPUA Magnum brass was not made to the exact CIP-specification for which Lapua itself had applied the CIP-secification.

I believe today the generic 45-70/.416 Rigby shell holder works just fine with newly manufactured Lapua-made 338LM brass.

Started out with 80 new Lapua 338s and 20 new Norma. One Norma had a a neck split after the 2nd firing. I'm on 8 firings with my Lapua brass and everything's hunky dory.

Norma is actually about 10-12grs heavier, if you can believe that, but my advice would be to get Lapua and get a couple/few boxes, as the price is skyrocketing. Norma works fine too and if it's a lot cheaper try some, but Lapua IME is lasting pretty long for a large cartridge case.

Re: Loads for .338LM

Wow - I have been collecting Lapua Brass for the past four months, the best price I found was at brunoshooters.com in Phoenix AZ. I just looked at the prices today, while the prices have increased for 2008 following the Lapua increase, Bruno is still very competitive.

Be safe, BSR

Yeah, as you know, I bought a case of Lapua 338 brass from Pettibone in Chicago in March and was doing some Ebay selling along with moly coated 300gr SMKs as kind of a niche thing, 50 cases/50 tips and I couldn't compete with Brunos even at my cost ($1550 shipped for 10 boxes.) His $1.49 a piece was even cheaper than the 2006 prices, IIRC, but boy...have times changed.

I think Brunos was at $2.04 last week.

I have two and a half boxes for myself and didn't sell that final box I had listed here at $185 shipped, but yippie for me because of non-precious metal increases!

I'm rich bitch!

My pet load for shorter ranges...<750yds is 85.5gr of H-4831SC under the two 250s, SMK and Scenars, as I shoot a 1:12" Sako TRG42 and seated to roughly 3.650" @ ~2775-2825 fps, 215M. I don't need to push it at the shorter ranges that I shoot.

I've also had good luck with ~87-89gr of VV165 and roughly a bit more of VV170. Tried H-1000 once and didn't care for the results at 100yds, so I'm sticking with those. I do have some RE-25 to fiddle with.

People seem to do well with ~95grs under the 300gr SMKs for ultra long ranges, but shoot 1:10" twists or faster.

Figure that you'll get about 70 rounds per pound at 100gr, more as you download them.

Am I reading this correctly? If I get a smk tip that is 300gr, there aren't 300gr in the bullet? Boy do I have a lot to learn.

I was referring to the powder charge. For 338LM target shooting, it's basically the 250gr Scenars and MatchKings and the 300gr MK. For the latter, a twist of 1:10" is preferable, as the tips are longer than either 250gr HPBTs.

I think that at ~86grs of go-go juice, I get like 85 rounds per pound.

Hey Chris, I bought 2x100 boxes off of you on eBay (B4 they hosed shooters). This IS a small world!
 
Re: Loads for .338LM

I have a TRG-42 in 338LM. I have about half a pound of IMR 4831 left and will be ordering more powder soon. Should I get eight pounds of Hodgdon 4831SC or stay with IMR 4831. I haven't had much time to test out the loads with the IMR powder but have noticed that MANY TRG-42 shooters use the H-4831SC powder. So, any suggestions?
 
Re: Loads for .338LM

I can't seem to find any Federal 215M primers anywhere. Would CCI #250 make much difference loading .338LM 300 grainers?

What length barrel? What chamber? And at what range. For a tight match chamber-not cut for bore riders. Start with 210grains of VV24N41.Also the same for H US869 and H50BMG. I use these also for starting loads with 800 gr. lapua solids.VV 20N29 is slower than 24N41 and may give you marginally better results with the 800 gr. bullet but if you shoot 750's also I would stick to 24N41 if buying VV. Use EXTREME caution working up 50BMG loads,not as forgiving as a 308.

Re: Loads for .338LM

I have a few questions?

Can I mail ammo in the mail to someone?

I have 4 total boxes (20) of Black Hills .338 Lapua I bought. One is 250 gr and 3 are 300 gr. I want to sell them because I got the .416 Barrett instead of the sako. SO, if I posted them for sale, could I ship them to someone on this forum? If anyone is interested, then let me know how much you would offer.

You can't ship ammo via the USPS, but rather FedEx and UPS. It's a bit of a hassle, but there should be no 'added' surcharge.

I first got the RCBS #37 shellholder (416Rigby) it did not work until I Dremelled it out, but the RCBS #14 works oerfectly.

This is with Lapua brass.
 
Re: Loads for .338LM

I'm using a # 14 RCBS and it will not allow the primers to fully seat using an RCBS hand primer. This is with 03 and new Lapua brass. I have a Redding #35 comming with my order from Bauer Arms. I hope this cures my ills.............

Re: Loads for .338LM

Heres my problem. I cant fit the 338 case in my forster trimmer, So #1 i need a new trimmer setup (Suggestions please). Number 2 what dies will get me started for the 338lm on my redding press?. #3 what does SMK mean, and where can i get fed 215's, didnt see them at midway, gaf, or cabelas?#4 what tools r good for cleaning the flash hole, primer pocket, deburring neck and reaming neck? thanks
 
Re: Loads for .338LM

#1 You can have your "Original" series trimmer modified to accept the larger collet,or you can purchase the larger "Classic" series http://www.forsterproducts.com/Pages/class_trimmers.htm. Buying the larger Classic series would be the way to go.

#2 Do a search on the dies.A lot of suggestions on the forums. I use the Forester Micrometer Benchrest set.

#3 SMK means Sierra MatchKing. My local gun store usually has GM215M primers in stock. You'll have to keep looking on the internet to find an online source.

#4 RCBS and the other reloading companies make various tools for cleanings primer pockets,deburring the necks ,ect. Just look at their online cataloges.

Please fill out your profile before the Profile Police come for you.

Re: Loads for .338LM

what collet works best with the forster classic for the 338 lapua mag. You have the option of collet #5 thru #8?.. also what pilot did u get?
 
Re: Loads for .338LM

The #4 is recommended for the 338 Lapua in the "Original" series trimmer.http://www.forsterproducts.com/cgi-bin/order_search.pl?list=338+Lapua+Magnum&num=25&words=338+lapua . The 416 Rigby,which is what the 338 Lapua's parent case was, recommends #4 collet in a modified "Original" series trimmer or a #5 collet in a "Classic" series http://www.forsterproducts.com/cgi-bin/order_search.pl?list=416+Rigby&num=25&words=416+rigby . The rim of the Rigby is .590" and the Lapua is .588". I elected to leave my Forester trimmer alone and use a modified Lee case trimmer. http://www.leeprecision.com/cgi/catalog/browse.cgi?1219814028.1034=/html/catalog/casecon.html. I ended up cutting down a 375 H&H case length gauge on my lathe to work with the 338 Lapua. Works very well. If you're going to use the Forester trimmer,call them first and see what they recommend.
 
Re: Loads for .338LM

yeah i called them today but it was after hours, so ill try again tommorrow. Seems that the hornady new dimensions dies are out of stock, the 250 scenars are out of stock , the lapua brass is out, everything is out. starting to get frustrated with all this stuff

Yes you are right!!. It can be quite frustrating. They are expensive to start out with so it's almost like stock up as much as your wallet permits when you can find them. Good luck man.
 
Re: Loads for .338LM

A few places such as Bruno's,Graf and Sons and Midwayusa are showing the Lapua brass in stock but not the 250 scenars. I waited over a month for a 500 count box of 300Gr SMK's to come in. You just have to be patient.
 
Re: Loads for .338LM

yeah, patience. Thats fine, just want to get the right stuff, makes sense is sold out... cuz its good, and everybody wants it. BTW the forster classic case trimmer doesnt even make a 338 lapua collet. I talked to forster today, great customer service, left a message, they called me back first thing this morning!, so im gonna modify my forster original and order collet #4, i just gotta ream out my forster collet holder. Think im goin with what Chris Garret told me bout, the hornady new dimension die set. seems like a good one. Not sure bout the micro seating stem though, dont know what it is for yet? dont know what i need all these bushing for either? seems like all i would need is the die set and a shell holder. If anybody else is looking for this stuff i got part #'s from midway to help your search out, but double check me on these things:
1) Hornady new dimension dies Part#779608
2) Hornady shellholder #43 338LM part#706368
3) Hodgdon H-4831sc product#112439

theres some more parts ill post later, I havent ordered yet so if anybody has any info on these parts or better ones, id love to hear it
 
Re: Loads for .338LM

All goin through the tube of my TRG 42 1:12 naughty stick 338LM

well i eneded up getting the redding type s competition 3 die set. And i love it

I got the Hornady #43 shell holder (i think its a 43, double check me on that!) and it works good as well.

went with the V V N560 powder @ 87.5 geez, the 250 SMK's and some 250 Lapua lock base bullets as well. All goin on my black hills Lapua cases that I shot one time so far, and as you guys said the brass all looked good. Im gonna stick with Lapua Brass.

My Overall Case length w/ bullet is ~3.663, the micrometer on the seating die is awesome!!

Like a lot of guys say, you dont want to full length size your case every time, cuz it breaks the brass down. Wonder what a good rule of thumb is for how often you should full size your case?

Still cant get any Fed 215 M's so i went with the standard blue box 215's.. i will report back on my exp. w/ how they work.
(if anybody knows where i can order some 215 m's, please drop me a line)

oh yeah, Im using a redding type s titanium nitride 365 bushing, partialy seating the neck about 3/16" to 1/4" from top of case.

dies feel nice when forming, just keepn them lubed real good, once i decap, neck size, trim, clean primer and flash hole, i just drop em in a bucket of warm water and liquid tide for 20 mins. and them blow them out w/ air then let them dry

The micro seater is a nice feature to have. It allows you to make fine adjustments to the seating depth without fooling around with the lock ring constantly. You can get a much closer tolerance.

As for dies, I really like the Forster dies. http://www.forsterproducts.com/Pages/dies_order.htm

Powders - you may want to check out the Norma powders (MRP and MRP2) and well as Vhitavuori's lineup. The Vhitavuori reloading manual is a great resource for the 338 Lapua. I think both of them have reloading information listed on their websites.

Watch out for the press - the standard presses will not accommodate the length of the 338 Lapua cartridges.
