Hi all, going to try handloading some truly unconventional bullets for .300 win mag this summer (maybe for Father's Day I can escape and do some loading and shooting).

they are on opposite ends of the weight spectrum. The first is the 120 grain Barnes tax-tx meant for .300 blackout. It has a bc of .358, and it's a Barnes bullet, while it might lose
Petals as 300 win speeds I'm not worried about "failure". I want to see if i can hit 4000 feet per second. That'd be wild! The bearing surface of this bullet makes one think it was specifically meant for the .300 win mags neck! And it's basically the same length as a 220 round nose.

the other is a Hawk 250 grain round nose. That's right, not 220, 250! Heavy hitter territory here. I have no idea what to expect. I know it'll stabilize in a 1:10 no problem, its actually a hair shorter or just the same length as a 180 trophy bonded tip, it's shorter by far than a 210 ablr. I know Barnes made an original in 250 grain as well.

I've included a picture alongside some other 30s.

120 tac-tx, 220 cil kksp (old discontinued Canadian bullet company), 250 hawk, 180 tbt, 208 eldM, 210 ablr.

anyone have any experience loading these or predictions for how these will turn out?

I would leave the rest on the shelf and only focus on the 180 TBBC and 210 ABLR, but I'm a stick in the mud. I remember reading an article about Jack O'Connor talking about 220's in 30-06. His observation was that it over penetrated on brown bears so he dropped down to 180's and never looked back. For that purpose I don't see the point in a 250 in 30 cal unless it's something like a Berger or A-Tip
 
Barnes also made a 225 spt. and the 250 RN and I have a few left. I haven't seen any since Barnes came out with the X bullets , both shot well. Years ago Barnes made some cool bullets ,if I remember right they had a 170 gr 6.5 bullet QT, Quick Twist and made rifles in something crazy like a 1 in 7 twist which is where we are today. Check out P.O. Ackley's books volume 1 and 2 interesting read.

I certainly will have to take a look at those books sometime. Ackley stands out as something of the Godfather of handloading and wildcatting wherever he's mentioned.

another man I wish was still around to talk to from a long while ago is Charles Newton. Designed the 250-3000 savage, was controversial for his velocity craze decades before weatherby was around. Designed a few cartridges disturbingly similar to what are touted as the newest developments of today (beltless standard length magnums). Look up the specs on the much acclaimed .300 PRC. Look up case dimensions for a cartridge called the .30 Newton. Shake your head and remember there is nothing new under the sun!
 
Although I've moved up to 8mm magnums instead of .30's, the Newton cartridges have always intrigued me. I'd like to build a .256 (shoots a .264 bullet, if I remember correctly) and a .30 someday. My 6mm-250 Savage has been a nice surprise.

Only difference is the Newton will fit a standard length action. 300 PRC OAL is 3.600. I wish the 300 Dakota had taken off more but oh well. 30 nosler is probably close enough

I have a 30 Newton
Had custom biult back around 2003.
Very efficient cartridge.

That 120 barnes sounds fun! well so does the big round nose but the 120 caught my attention.
The guys over on hammer time are discussing the light weight 30's among others in a thread called Hammered down under. Your little bullet should be a pretty similar idea!!!
 
Look at Ackley's vol #1 I think page 242 30-378 Arch . I had #11 Built in 1987 , I've got all 3 case variations in my collection , short version ,longer version and a version that they turned the belt off the 378 weatherby , the end result is the 300 wsm . I sold the rifle in 1992 against my better judgement ,3 weeks ago I bought it back from the guy I sold it to, been in the safe for 28+years and he shot 20 rounds through it . Have 9 boxes of once fired brass, 2 boxes of loaded barnes 225 and 250 . can't wait to get to the range. I'm going to pull the bullets and reload them again. so many powders to choose from now compared to 30 years ago. wish I could find some 225 spts original ones , I would like to share photos ,but have a older computer and can't get it to work.
 
I loaded the 250gr Hawk in my 300wm years ago. It shoots well and I killed some deer with it but never got to put one on and elk. Lots of recoil. Have since stopped using Hawk bullets due to terrible customer service and they didn't reimburse me after their screw up.
 
Why the 120 tac-tx and not the 110?
I've been perusing some old threads of mine and realized I never answered your question all those months ago.

It was in stock. That's about all there was to that originally. But no going back! Even if you could get the 110 going a full 200 fps faster than the 120 (which I actually doubt), the 120 is still flatter shooting even just regarding max point blank range because the bc is so much higher than the 110 as to offset any speed advantage within 150 yards or less. The goal with this wasn't simply the highest chronograph number possible, it was the flattest hold on hair .300 win mag deer load possible, period, regardless of bullet weight or initial speed. Went on to achieve this with flying colours, got 4050 fps. Run a bc of .358 (and it's probably higher than that at these speeds) at 4050 fps muzzle velocity. Out to 500 yards there's very little that touches this for flatness. Took two deer this year. It killed em real dead haha. Success.
