Title: 37XC build
Post by: jasnt on July 05, 2019, 06:00:54 PM
First component of the build got picked up today. 
Savage 112 target magnum in 338 lapua.  I was going to sell this barrel but I just couldn’t help but play with it.  Loaded up a preasure test with h1000 and 300 gr bergers. Found a nice node at 2935.  I’ll play with that till she levels out.  The target accu trigger is nice. Set at 1.5lbs for now,  may lighten it up a bit more.  Brake definitely tames the recoil, was like shooting a 308

my thoughts too. Had a slight crater of the firing pin but nice round conners and no ejector swipe. Bolt opens with one finger. 2975 has slightly stiff bolt lift and I backed off

Using magneto speed so I trust the speed

Not sure what was up with my v3 yesterday day but could not duplicate that load today.  Speeds where all over with es of 45. Dropped down to 94gr h1000 and 2816fps.  With es of 3 and 1/2 moa.  Hope to stretch it out tomorrow.

Post by: b23 on July 06, 2019, 11:24:48 AM
Am I reading that right, you dropped down to 94gr H1000?!  And that's with the 300 or 250 gr. Bergers??  Either way and even seated way out, that's well above book max.  With 300's you're almost 10gr above Berger's book max and with 250's your 4gr above their book max.
Title: Re: 37XC build
Post by: jasnt on July 06, 2019, 12:15:19 PM
Yes 300gr and yes 94gr.  No preasure signs what so ever.  With hornady brass no less and cci 250’s and jammed 20k.  I’m comfortable with the load

This scale has never been calibrated so who knows what the charge really weighs. All my cartridges end up over book max
Title: Re: 37XC build
Post by: jasnt on July 06, 2019, 03:15:59 PM
This is from Hodgdon.  I’m 2gr over their max listed and not compressed. My col is 3.930

it would be if I hadn’t sent yorke his unithroater back lol. This thing could be taken out quite a bit. Should have my new barrel ready to mount up in a couple months or so.  May just ream this barrel to 33xc since I’ll have the dies and go/gage anyway
Title: Re: 37XC build
Post by: Magnum_Willys on July 07, 2019, 09:44:54 AM
94 gr is max on my 3.95 coal 300 gr Lapua but thats with 215 primers and SMK's.  With a slow batch of h1000 and cci's with Bergers I could could squeeze in another grain.

Dropped down to 94gr h1000 and 2816fps.  With es of 3 and 1/2 moa. 

This is where I'm at with H1000 and a 28" tube.   Generally use rl33 or n570 to get up in the 2845-2870 range

great reviews, few folks recommended the t4 but for a sub 25lb .375 I’ll go T5. Plus the T4 would be smaller than my muzzle

Been looking at getting a chassis for this thing but not liking the options.  Stock is ok and I did bed it and does have pillars but it just doesn’t fit me quite right and cheek rest could be higher. 

338 barrel has smoothed out nice.  Was able to drop down to 93gr of h1000 and still stay in my node at 2825.   



I hate waiting!!!!

Do you have an idea what kind of chassis you're looking for? It's tough to find them for single shot rifles.

dosent need to be a single shot chassis.  It will fit any la savage chassis with top bolt release.  I’m only running front and rear action screws now and it shoots better than it did.   Need long forend, adjustable length and cheek and buttpad cant.  Wanted an other XLR evolution but they don’t do la savage.  May go mdt and use XLR buttstock  also looking at vendetta precision  but they are new and no reviews plus this is their first run of chassis so I’m nervous but the price is low due to preorder.  I’d like to keep it under 1400

I kinda figured this beast wouldn’t be a hunting gun, I mean what are you going to shoot T-Rex?  I‘ve been looking at the bipods that some of these extreme long range shooters are using with their heavy guns.

What are you thinking for extending your bipod over the forend? Picatiny rail?

That little Win Mag looks cute compared to the 375. :chuckle:

I've been thinking hard about a 416 Barret but I don't like the massive BMG actions. I had a reamer drawn up for a 458 off of the Barret case and I was very close to building it but found a good deal on a CheyTac action and got distracted. A 458 would give you more powder options, but fewer bullet choices.
Title: Re: 37XC build
Post by: jasnt on October 13, 2019, 05:50:17 PM
Got the barrel chambered about 1/4+ of the way. Only 3 more inches to go lol

458 would have better splash.  When you go that big there are really only a few good choices any way.   650gr Lazer would definitely kick some splash

Going to have to shoot it with out the break to use my magneto speed as the brake is too long. I did strap it on using the spacers and strap had to be on the brake. Bad idea. Strap was clean of the port but sill burnt the strap a bit and I quit that real quick.  Starting load was 2900 with the 350gr smk.  Been having troubles with cci 250’s. Two different lots and both are bad :bash:  bunch of duds and few went off after 4th time the firing pin hits them. Switched to federal 215m and no issues.  So far the worst load was 3/4 moa.  Will check back when I finish load work and get speeds.  Wish I had a lab radar for this.

Seems to be coming along good, speeds are definitely up there for the heavies. I would like to have one of the Labradars too, hopefully here in the future I'll buy one. I'm still using the old style Caldwell chrono which shows 1 of 3 shots  :bash:

This may or may not interest you but thought I'd pass it along anyway, Hornady is coming out with a new 390gr .375 Cal A-Tip bullet.  Per Hornady G1 .987  G7 .497

If your having misfires with CCI 250’s you most likely have something wrong with your ignition in the bolt.  I would first check firing pin fall.  Pretty easy to do.  You want to me at least .240”.  I have seen this happen with certain triggers and the action not being timed.  It does effect accuracy as well.

at .046 firing pin protrusion.   Having the misfires in my 300wm aswell so I don’t think it’s the rifle.   Both bad lots came from same store so I’m wondering if it’s a storage issue. Never had a problem with cci primers ever.

It’s how much it falls measuring from the bolt head.  Not how much it sticks out of the bolt face.  It’s how much slam the firing pin has against the primer.  Timney are known for this.  Except the elite.

Neither have a timmeny trigger.   The 300 wm has punched 1047 cci primers with out an issue till these 2 cases has never had a hiccup

Don't be a wimp, pull the brake and shoot it like a man to get your velocities. :chuckle:

I've never run my 338 CT pistol over a chronograph for the same reason. I got my muzzle velocity by zeroing at 100 with a know bullet then measuring drops out to 600 yards. It's a pain, but it's been close enough to get me on target to 1800 yards within 2 shots.

Post by: jasnt on October 25, 2019, 05:17:21 AM
I’ll probably shoot it with out the brake for speeds. Then verify at range. I know the brake can affect speed but how much idk.   Figure it’s better than paying $150 for the adapter.  That’s another box of bullets.

I’ll see if I can get some kind of adapter made for the Magneto. The member formerly known as Jay_sharkbait owes me some work so I’ll get him to design and 3D print something to try out.

Well I shot it with out the brake. Not bad at all really.  I’m at 2945 without the brake.  Screwed on the brake, held 14.5 moa high and nailed the 735 yard plate.  I’m thinking I’m pretty close with speed but got plenty of room for more powder.  Hopefully I’ll get more time this next week to play with it.

Got the smk’s dialed in well today.  Haven’t checked speed yet.  As usual the poa is a bullet hole cause I never can seem to find my sharpies when I need them.  3shot group
120gr h1000

Not bad for a hand chambered barrel and a factory action

It is, very happy with this build.  I’ve considered getting some rcc brass for this thing.  Would probably gain another 50-100 fps.  It’s already barking on the heals of the Chet tac with less powder.

Can’t go to my long spots yet so I did a little at home today.   Some gusty winds but I think I did ok.

It’s all about the fit.  Plus I need a rail in front of my scope for a macro Charlie Tarac from tacomhq.   I like me butt pad canted 10deg to the left and raised up till the top is even with top of action. Same chassis as my 243.

This morning didn’t go well. First I could not get my GoPro to work with my phone. By the time I did the battery was low and I left the extras on the charger at home. By this time the sun had risen and the rocks were light up good. Thought I got a range at 2480 but latter checked google earth and it said 2566. So I setup and the go pro was getting washed out. Had a heck of a time getting white balance right. Finally get set up and shoot. No spot, shoot one more and no eject. Had a bad peace of brass from load work that ended up getting a small chunk of rim bit off by my ejector and thought I had tossed it but it ended up loaded, when I slipped it in the rifle some how that bad spot lined up with my ejector claw. So peace of brass is stuck in my chamber and no cleaning rod to push it out. I fiddled with it for a min before throwing in the towel and heading home. Maybe next week

I had a slightly wrong size shell holder in my priming tool I was tring to get by with and it scarfed case rims like that.

Had sessions like that - all ready then fog, or batteries dead, or lands grew overnight since last checked,  or someone cutting wood where I was gonna setup, or wind is crazy,  rain starts , etc.  heh.  Better luck next time out.

Finally got a chance to get back up to my 2500 yard spot. 3rd round impact! Very happy with results.
2566
8 mph wind coming up the mountain had me dial 4 moa less elevation and left to right wind above los had me holding 3 moa left.
