New to the caliber from a reloading standpoint.... just made a deal on here in the Classifieds for a Winchester M70 Heavy Barrel Varmint. 26" heavy barrel, 1:9 twist.

I bought a bunch of 77gr Nosler Custom Competition bullets years ago at SPS with different ideas in mind, and they've say patiently since.

A little google-fu indicates that these should be good candidates for shooting in the new-to-me Winchester.

What powders are good for this? Saw a little bit referencing either/both RL15 and Varget. Seems like a lot of good 308 powders are mentioned with the 223...?

I also have a hunting rifle 308 to start loading for my kid. A powder I can use in a few rifles means I can justify (read = rationalize) buying an 8lber vs 1lb jars.

4064 too fast?

Thanks, all.

8208 XBR, TAC, Varget, H4895, RL15 are all good. I've never tried 4064.

I shot a ton of Varget with heavy bullets in my 223.
It was just so good, I didn't experiment any more.

Push them fast, 1-9” might be a little slow for optimum performance. The extra barrel length will help.

Varget did for me with 75 ELDM in a 1-8” Tikka.

So I was mistaken. The bullets I have are 80’s.

They’re loooooooong. Probably not a good fit for this rig.

Buy some 75 ELDM. Try my recipe (work up) and let me know.

they will work just fine.... it can still push 80s from a bolt action in the 2700 to 2800 fps MV
without being over SAAMI specs...and they will stabilize just fine with a one in 9 twist.

Make a dummy round, and see how far into the case body you have to seat it to clear the throat limitation of your rreceiver...

i have a single shot Savage BVSS in 223 with a one in 9.... its a very accurate target rifle with those longer bullets...

If the 80's don't work for you, hunt up some 75 Hornady HPBT or drop down to the 68 - 69 gr versions. Powders that are good in both are pretty easy, my list parallels NVhntr's.

Here's what QuickLOAD spits out when asked for a list of powders suitable for that combination. The results actually included a lot more, but I edited out the absurd stuff that suggested 114% case fill, or predicted 87% of the powder would be burned, etc

I was surprised to see Varget so far down the list, but real world results may be quite different from these predictions.



Code
Barrel Length      : 26.0 inch = 660.4 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 55000 psi, or 379 MPa
or a maximum loading ratio or filling of 114 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

38 loads produced a Loading Ratio below user-defined minimum of 70%. These powders have been skipped.

Varget.

Seafire has a ton of .223 info. Get on his good side and you'll be good to go.

I've had more than one source suggest the Hornady 75gr HPBT. Any others that are pretty solid choices for this twist? If I'm gonna buy some bullets, no sense in reinventing the wheel, so to speak.

If you are looking for game bullets I'd sure try 62 Gr. Speer Gold Dots...in varmint/target bullets the 68 Gr. Hornady BTHP...and the 60 gr NBT

Not really looking to kill big game with it. I do have some 64gr Nosler BSB’s though for that possibility.

I’d be looking for range and woodchuck ammo.

I’ll check out those recommendations. Thanks!

Either the 68BTHP or the 75 BTHP from Hornady...

powder options for both accuracy and velocity....

28 grains of H 380

27 grains of RL 15...

27 grains of IMR 4320...

24 grains of H 322...

25 grains of Benchmark.

25 grains of 4064, H4895 or IMR 4895.

I like S & B primers...SR
