Well my daughter wants to get a cow tag next year. I've got plenty of rifles but my eye keeps going back to an old 24/27 I sporterized in HS . Has an old cut down stock , a fixxed 4x monarch , Tunney trigger and best of all I still have the dies and a pile of brass .

I pulled her out and the stock is horrible hahah. So I ordered a Boyd's laminate .

I'm working on getting a 3x9 with a some type of hashed reticle for shooting up to 300yds.

I had some old 180 NBT still waiting for me . And plenty of powder on the shelf ( 3031, h4350, h4895 , tac , 4320)
I cleaned her up and decided to take her for a test run and see if this hair brained plan was worth it . So I foamed the bore and gave her a good bore douche and put her In The truck

I started by grabbing a box of the old factory corelockts ... which this gun hates but wanting to get her hot I figured what the heck. I also went down an early 2000 rabbit hole looking for euro spec loads for the 180 nbt . And settled on 4320 @48gn with an oal of 2.020 and loaded up 5 to test .

I ended up at an old gravel pit yesterday with the boys after doing some rock hounding for benitoite . And as I remembered the corlokts loaded and shot like dog poo atleast all 20 were under a 6" pie plate at 100
Then came the reloads . Mighty stiffer than the factory loads but easy bolt lift , no primer bulge and no imprinting on the head but all 5 under 1.24" at 100 .

Perfect ! If this is my starting point I might be in for a damn fine 300yd gun . So next steps for the reloading shack ...
- load up to find pressure 48.5 /49/49.5...
- keep oal on NBT
- once NBT is figured scrub the heck out of barrel and ammonia etch
- repeat with 180 tsx
For the gun ----
- decide weather I really need the irons on it because if I want them I will need to inlet this pretty Boyd's stock
- possibly cut barrel down to 21" ( I love short quick handling guns and this powder is on the faster side so not worried about incomplete burn . ( plus side will be new crown )
- mount new 3x9 scope . I think I'm set on the scope from another fine ROK member . But unsure if I want to replace the old 1pc leupold mount and change to a weaver style . (Input appreciated )

Ok so that is big info dump I know but feel free to add any opinions or thought , experiences.
 
Well she got a new stock . I epoxy bedded the front lug . Irons came off . 3x9 Burris went on . Barrel cut to 21"
And new recessed crown . Loaded for pressure signs but nothing held as tight as the 48gr 4320 load . Loaded up 40 and need to chrono . Think I'll stay with the 180NBTs this season
I'm going to try some 180gr tsx's as soon as I can get some cfe223
 
What’s the caliber? I didn’t see it mentioned?

With the load you are talking about you mentioned trying some 180 TSX bullets? Personally I have seen Barnes work way better if you go lighter and faster. It would also help reduce recoil if a smaller shooter is using it.
 
My old model 97 got the nickname "The Old Crowbar" many moons before I owned it. Grandpa and dad shot it before me at the deer camp in Northern WI. 107 years old and still shoots well. 8mm Mauser.

8mm x57 Mauser
The only other bullet available is a 160ttsx and the store had the 180s for 30bucks a box . Not to much to worry about on the recoil my daughter is 6’ and tougher than nails . And I’m loaded with a faster powder so not to rough
 
My guess is that the 180 NBTs will work better than the TSXs, both in load forgiveness and terminal performance. The 8 Mauser isn't a screamer by any means and the TSXs need speed to work. But, I also get that some prefer to use monos.
 
Yes I agree the monos love speed but if I’m going to use this gun in my home state I’ll have to use the mono . I had a lot of luck on my 308 when I first switched to monos with a 168gr trophy copper . It was slow but nothing ever got away .
 
Id be interested to see how 180s perform. I ran into some 200 gr partitions for my 8mm and got them pushing 2600 fps. They were howitzers on whitetail but sadly I only have like 6 rounds left.
 
I had a similar rifle. I shot several large hogs with hand loaded Barnes 180’s. Ranges were approx 50 to just under 300. Terminal performance was excellent. I wouldn’t hesitate to use it on cow elk.
 
Sierra 175 PH gave me the best accuracy in my K98, only issue is bullet is seated real long.
W748 max load.
