250- 3000 and other quarter bores

The Sierra 75gr HP Varminter was discontinued.
I bought 3,000 while they were available.

My build this year was unintended.
Someone offered me an E.R. Shaw barrel in 257 Roberts for $100.
It is now paired with a Savage 111, and reamed to Ackley Improved.
Mostly looking at bullets in the 115-120gr weight for it.
 
I have 80 of the 75s left; I had already switched to the 70 gr BlitzKing for my Roberts varmint bullet, so it's a good use for them. FWIW, those 75 Varminters go 3,400 from the Roberts, 3,234 from the Savage 20, both with 24" barrels.
 
The 75gr HP Varminters are running about 3,150 from my 24" barrel using Alliant Varmint.
Not the fastest loading, but man are they accurate! Especially from a sporter barreled hunting rifle!

Got my trigger in today.
Also found out my barrel shipped today. Should show up on Wednesday.
Only took 18 weeks.
Was told 12 when i ordered.

Last barrel I ordered was quoted 10 to 12 weeks; ended up taking 5 months--but it was worth the wait, a great shooter. What I don't like is a barrel that takes a long time AND is poorly executed; meaning it sat in the pile and was rushed when they finally got around to it.
 
I like the quarter bores. At one time or another I've owned the .250, .257R and the 25/06.

I bought my first .250 more than 50 years ago, and my second near 40 years ago. They were a Ruger M77 and a Savage M99. The Ruger is still so unbelievably accurate it's truly amazing. It's lightening on deer and shoots under .5" at 100 yds and smaller. The 100 grain bullet is my favorite and is used on deer. The 87 grain is just as accurate. The M99 is very accurate and a sure deer killer, but not on the M77 level.

I've had two .257R rifles, a Ruger M77 and a Remington classic M700. The M700 was by far the best but only a little more accurate than the long throated M77. I took lots of deer with the M700 and the 100 grain bullet. Two 25/06 rifles have graced my safe, a M700 HB varmint and a M700 sporter. Neither were used much but I wish I had one of them back. The .257R sped a 100 grain bullet at between 3200 fps and 3300 fps without going max on powder charge.
 
I received some of the new Barnes 101gr lrx in the mail today. Barnes told me they have no data for 257wby yet but use 100gr ttsx as a starting point and that the g1 bc is .400. The lrx are slightly longer overall with more bearing surface and a longer base to ogive. The ballistics look really promising if that bc holds true.
 
Please let us know how the new Barnes works out for you!

Another option for Varmint bullets is the 90gr Sierra BlitzKing.
Has proven effective on coyotes, and depending on wind, fairly accurate out to 500 yards.
I use them in both my 250 Savage & 257 Roberts.

I'm looking forward to trying out the new 110gr Tipped GameKing.
If their advertized 0.447 G1 holds true then it will definitely help at longer ranges!

I wish i could get something heavier than the 90gr Raptor to shoot jn my 1:10 twist barrels from Cutting Edge.
Their MTH line shoots great in my 7mm's.
 
Well, my Shilen barrel finally arrived.
Recoil lug pinned to receiver, barrel on & headspace set. Trigger on & adjusted.
Now to get the stock built.
 
You can't go wrong with a 250/3000
1:10" twist was standard for their barrels

I take it easy on the little break action, but she shines!
22-250 as been the most prevalent donor brass for conversion
Thanks,
Jimmy
 
Mid 70s, college days, it was Rem 700 .25-06. Never should have let that one get away. Mid 80s, it was. a Rem 700 .257 Roberts. Had it cut to AI. It was a one ragged hole shooter, with 117gr bullets. So much so, a guy on the rifle range made me an offer I couldn't refuse. I should have, but couldn't.
 
I built a 257 Roberts AI on a Savage 111 this year.
Cases are fireformed. Now doing load work ups for 120gr Partitions & 120gr Sierra HPBT GameKings.
Would like to do the 115gr Berger VLD, but don't have enough.
I'll end up using them in my Ruger 77 MKII in 257 Roberts.

Finding bullets that i want has been a PITA this past year!
 
Ran a ladder test for the 257 Roberts AI with 120gr Sierra HPBT GameKings using Norma MRP powder.
Not too happy with it.
Seems too slow burning. (Roughly same burn rate as RL22).

Going to try something a little faster burning.
IMR 4831, RL19, Ramshot Hunter.
May play with Alliant PP4000MR.
 
I get good results with a standard Roberts and 117 Sierra ProHunters over Re-22 or, recently, IMR-4955. The Enduron powder acts like Re-22 in this application, more like Re-19 in others. I'd sure like to hear how 4000-MR does.
 
My go to powder for my 257 Roberts with 100-115gr bullets is Hodgdon Hybrid 100V.
I'm loading to +P pressures. It's done well with regards to velocity and expected accuracy.

My 280 Rem & 284 Win up through 150gr bullets have been reacting well with the Alliant PP4000MR.
 
My standard 257 AI load is a 115 gr Ballistic Tip with H4831 SC. It works for me.

I would guess H-4831 SC and a 115 BT would be worth a try with a 250 -3000 standard or AI if you had 1 in 10 twist
Early on,before Nosler released the 115 BT, I was using 100 gr Sierra BTs and IMR 4350. That performed very well. I'd guess t would be good in a 250-3000
 
My backordered Sierra 87s arrived, so I am going to work them up for my old Savage 20 (the slow twist gal). Sierra got 3,100 with H380 and Alliant Varmint. I have just enough H380 left to load a series, so we'll see how she does.
 
My go-to powders for 250 Savage are IMR3031 and W748. For the 257 Roberts, it was IMR4320 and IMR 4350. But there are so many powders out there now that everyone can use different powders and find those "pet loads".
 
Well, the barreled action on my bench rest rifle is put together.
After some phone calls to Wolfe Gun Springs, i finally have the trigger down to a nice, consistant 8 ounces.
Now waiting on the stock builder.

Since the mainstream bullet makers are still so overwhelmed, i've started looking more at the mono bullet makers.

Hammer's Absolute Hammer are showing a velocity increase of approximately 200 fps over like weight bullets.
Now to talk them into an Absolute Target Hammer.

I've shot Cutting Edge MTH line in my 7mm's. They gave excellent accuracy.
I'll get with them on a solid target bullet.
 
Got the Savage 20 back to the range this morning. Sierra got 3,100 out of their 87 Varminters with H380, but mine could only manage 3,060. But, at 0.4 gr. below their max, mine ran 2,998 with a SD of 1.9. All grouped pretty well, albeit 9" high. Since the aperture is on the bottom, I need to add a minimum of 0.0725" to the front sight (yes, I passed geometry). The 20 has a blade-and-bead front sight mounted in an axial slot. Somehow, I need to replace it or add a bit. Since I used up my H380, I'll go to BL-C(2) or 748, but it looks like my old girl could be a deerslayer afterall.
