I have started several threads on cast in a 300W. I shoot the Lee 200gr in my AR and my savage. Because of the lower friction, I cannot generate enough pressure to cycle my AR with a carbine gas port subsonically. I would love a 250ish grain plain base, no gas check needed for 1000fps. No hollowpoint needed. It should be a super long bore rider so it gets close to mag length to improve feeding in semi autos. :twoguns:

I have gotten 210 gr leads with 10.5 gr of 1680 in my 16M1S upper to work.
Love lead and a lot cheaper to shoot.

Has anyone seen or tried this Hock 225 grain mold.

Hoch bullets are some of the most accurate made. According to DUKE V. He uses them in all of his long range matches. Nose pour. Check out Cast Boolits.com. They have all kinds of info and group buys going all the time, as the above post indicated. They presently have one going by NOE ENT. for a copy of the Lyman 312284 215gr. with or without hp and gc. with multiple cavityies available, page 2 of Group Buys under Blammer small group buy. It is not scheduled to start production until Jan so there is plenty of time to get in.

That looks nice but I am thinking some tailored directly to the Whisper is an autoloader for me. I want it heavier to help get it subsonic, I want a crimp groove, I want it plain base, I want it close to mag length, I want the bore rider diameter right at 0.3005" or even 0.3000" so there aren't issues with it hanging up going in. I know that a tighter nose fit equates to accuracy, but I am looking for blaster boolits. I want to shoot my whisper fast and cheap without gas checks.
I might even want a bevel base to aid in progressive reloading. I am going to get a mold designed once I get my chambers cast or reamed to 300BLK. I'll post it here and cast boolits. I am leaning towards getting it made at Accuratemolds.com

Please keep us posted on your work and what you ultimately have designed. Between the guys here and on castboolits, I'm sure there would be a bunch of us interested in something like that.

Even if it has gas check, one is not needed or will it hurt without if run sub.. Let us know how it goes. I have bolts and single shots but still use gc's due to a suppressor. Don't shoot that many at a time and keep inside of suppressor coated. Hope you find a good one...

Its not such much the cost of the gas checks, its the lubing process I'd like to keep cleaner and easier.

That is the one thing about cast that I really dislike doing. Have not been casting that long, but you have to do the bad with the good.

Would this work for the whisper leads also?
