CB for .300 Whisper

[simonbos]

Does anyone have a recomendation for a cast bullet for a 13.75" 300 whisper barrel (1-10 twist)? This is for silhouette shooting.

Thanks,
Simon

Welcome to the board. If this is a Contender barrel, I would try the RCBS 165 grain silhouette bullet first. This one is available from custom casters, but you wouldn't have to cast many to pay for the mold. I have used it in a .32-20 Contender barrel, and it is very accurate.

Simon,

I would say that anything over 165 grains and the trade off is too low of velocity. But if it has been throated out some, then you have more options.

So how long is the throat in that one?

[redneckdan]

the idea behind the whisper is heavy ass bullets at subsonic velocities. what type of load are you looking to run..

[versifier]

As heavy as you can go, that's what it was designed for. Start with 165's, I would think 180's or 200's would do you, but if heavier will stabilize, why not? COTW lists weights up to 250 and suggests you check the SSK website for data. It's probably for jacketed, but at those weights and slow velocities, it is a realistic starting point for the heavies. I bet you can order a selection in different weights from Bullshop to see what your barrel shoots best. Do you me to post a list of the COTW loads?

[simonbos]

Thanks for the suggestions. I have a copy of COTW...didn't think to look in there!
From some of the other sources I have seen it looks like < 220gr will work in a 1-10 barrel at sub-sonic velocities. There appears to be advantages to keeping the velocity down and the weight up; it seems that the terminal velocity and drift are better that way.
I checked the Bullshop site and didn't see any specific bullets listed...maybe I missed something.

Thanks,
Simon

On my home page there is a link to links, and from there there is a link to auctions. There you will find pic's on each boolit auction. Remember some auctions are down at times due to expired dates but always get relisted the next day. Any questions, I am easy to find. If I'm not making boolits I'm here.

Dale, I think that may have a typographical error in it. Closest I can come is CWOT which translates into "Complete Waste Of Time". This from a list at AcronymsOnLine.com. For some reason I can't link to that site, so, with apologies to everyone for the length of this post, I will paste the list in here. I expect it will be of interest to others as well:

Dale,
thanks for the link. I placed a few orders. Are there options on diameters? The .303 bullets I ordered are going to be used in a .313 bore 91/30 Nagant. The other 308s are for the whisper.

Cheers,
Simon

Cartridges of the World

[floodgate]

Dale:

As noted by several of the gang, "COTW" refers to the late Frank Barnes' "Cartridges of the World", first published by the Gun Digest folks in 1965 and currently in its tenth edition (2003), updated by Stan Skinner and available from Krause Publicatuions, www.krause.com

It is the BEST one-volume reference for cartridge identification, history, dimensions, sample loads, and sources of brass for odd-ball ones - also a few choice anecdotes. Not perfect - there are a very few omissions, and a VERY few errors - but Barnes said it best in the Foreword to an early edition: "If you were travelling to Mars or some other planet by rocket ship, and could carry only one book on cartridges, we sincerely hope it would be this one." I agree. It should be on every reloader's and gun-nut's bookshelf, alongside the latest Lyman Reloading and Cast Bullet manuals, and the Lee 2nd and Speer 13th Edition handbooks, as a minimum. If you are an experimenter, I would add the new second edition, just out, of Donnelly's "Handloader's Manual of Cartridge Conversions", www.stoegerpublishing.com.

No, I am not employed by any of the above firms, but I do refer to at least one of them daily.

Simon welcome. I am pretty much a newby to casting but have jumped right in feet first.
I do have a bit of experiance with the 300x221 aka 300 Whisper. I bought a 30-20 barrel and it was so close and had a rime I traded the whisper off. I don't recall the exact load but it was AA#9 behind a 190 Sierra. Anything much heavier or longer wouldn't fly well for me. I fooled around with trying to shoot subsonic loads, I got pretty discouraged at my results. The barrel shot better with a standard load. Your milage may vary if this is a custom barrel too.
I am like fourarmed and use the RCBS 165 grain sillhouette bullet. I have also used the RG-4 that is dropping about 200 from my alloy. It shoots fairly well to, though I don't use it much. I have some of the GB 155's loaded up and ready to play and see how they work.
As to load data I myself pretty much am right back to where I was with FLGC stuff.

I shoot my Whisper a 10" Contender...so your results might very. Remington (221 fireball) brass is used in all loads listed.

RCBS 30-150 FN cast of air cooled wheel weights; Winchester Small Pistol Magnum primers; 18.3 grains, Winchester 680; 1.930 oal...2063 fps at 30º 1¾" 3 shot groups at 100 yards. these RCBS 30-150 FN 's weigh 168 grains.

Lyman 311679 cast of heat treated wheel weights; Remington 7½ Small Rifle primers;
14.5 grains, Winchester 680; 2.211 oal...1580 fps at 45º 2" 3 shot groups at 100 yards. these 311679's weigh 208 grains.


The RCBS 30-150 FN fits the short neck and throat of the 300 Whisper better than any of the other boolits that I have available. I also tried the Lyman 31141, but it was too long in the driving bands to seat the gas check in the neck and still seat in the throat. The RCBS bullet is: .850" long; it has a .450 driving band length; and .400 bore ride length. The four barrels that I have been able to measure average .311 throat. The RCBS mould drops boolits about .309 and leads slightly because of this.

Reloader 7, IMR 4227, Win 296 / H110 are other great powders to try in the Whisper. SSK Industries, RCBS and Hornady have published loads, a polite request will get you copies. I use starting loads for condom bullets with the slower powders and work for accuracy, always mindful of pressure. Read the articles from Mike Bellm on Contender loading http://www.bellmtcs.com/FAQ/Experiment.htm

I’ve never shot silhouette with the Whisper, so I could only offer opinions...not facts that you asked for.

The Whisper was developed as a suppressed round that would fit a M16 upper for special opps

for the sportsman it is a great round...I shoot mine with real boolits in the Deer woods and practice.

[felix]

Looks like we have a genuine case/bore size (221/30) for 680/116 powder other than using condoms. Great show, Greg! ... felix

Thanks to all who set me straight on "COTW". I have a copy, AND a copy of Donnelly's book as well as Howell's "Custom Cartridges". Can't have too many references.

One thing I might add to this thread. I had my best luck using 222 brass instead of the 221. The 222 brass was just enough thicker that it did a lot better, groups showed it too. No neck turning on this either. Also the shoulder seemed to form better IMHO. You positioned the shoulder rather than blowing it forward and out a bit.
This was in a factory TC chamber, other mfg's should do fine with the 221.

I have 2 Whispers. One is the 1in 10 twist Contender Barrel from the custom shop.

The other is an AR-15 top half which has the 1 in 8 twist to stabilize 220 grain bullets.

You can shoot 220's in the Contender as long as you stay supersonic. Go below supersonic and they will hit the target sideways at 50 yards and they'll be all over the paper.

On the other hand, Im using a 220 grain Sierra with 8.2 grains of 4227 for the AR. This load is very accurate and also operates the rifle in the semi auto mode whereas the faster powders do not cycle. The is for suppressed loads moving at 1050 and is very quite with my suppressor.

For brass forming, Ive had the best luck using .223 cases. Cut off at the shoulder and run them theough the sizing die. Its easier to neck down than it is to neck up and there are NO rejects from splt necks being sized up. The .223 brass is cheaper and easier to find.
