I'm bored pretty much stuck at home. Trying to think of a wildcat to consider putting together as cheap as possible. I have a "junk drawer" of misc. bs. parts that might help. I've already built a modified 7/300 Practical that is badddd azzz. The damage it inflicts at 300+ yards is unbelievable with a BT. I'd like to build something a little more reasonable and can't think of much of anything reasonable. I'm thinking 6m min. to .30/32 max. I'd like it to work out to 400 yds, 500 if you shoot it like a howitzer. I have most cases, dies (fairly common ones anyway) and caliber bullets. I can't really come up with anything reasonable that hasn't ben done. I don't want a fly swatter or an elephant gun.
With the brain trust here I figure someone has thought about this themselves. Lets se what you got, no .22 Earsplittenloundboomers please, although I would like to shot it one time, if my shoulder would take it. I MIGHT be willing to gamble. It night be worth it, after all.
Let me hear a variety of thoughts. I'm looking forward to this.
I like to wildcat, and for my latest chambering; I wanted to arrive @ a wildcat taylored to my needs, along w/ the performance & accuracy I wanted...... but w/o all of the often associated wildcatting costs.
For my shooting, I wanted a wildcat that would cover both varmint & target work, and also give me a valid 1,000yd capability. I like to shoot groundhogs, which was a natural fit w/ my experiences as a NE Indiana farm boy.
My first wildcat was .35 Remington necked -down to .224" calibre ( " .22-35 Remington " ), which I designed to give me more terminal performance capability than the .22-250s I had been shooting.
I wanted to cover ranges out to 500 yd using a 55gr varmint bullet, and went with a 24" SS Hart 1-14.
Later....I also tried .22-35 chambered in a 28" SS K & P 1-8, shooting Hornady 75 "A"-Max exclusively in it. While the rifle / cartridge did provide 1,000 varmint/target capability, my aging eyes compelled me to design a new 6mm wildcat; to address my updated shooting needs.
To save money, I considered the use of a chamber reamer for an existing 6mm cartridge, and simply have the ' smith run the reamer in " short "; to provide me w/ my new wildcat... as-long-as it would have sufficient case capacity. I quickly settled on use of a 6mm Remington reamer, and specified that it be run into the barrel, until a nominal .466" base diam was achieved. This allowed me to use 7 X 64 Brenneke brass, which is .308 bolt face compatible; and ' " rimless ". 7 X 64 has the .466" base diam required for my wildcat. So.... NO custom chamber reamer required !
I call the wildcat " DEEP 6 ", as it derives its case capacity via the classic method.... by being long enough. This means a " deep " powder columne compared to the newer short/ fat cases; hence the moniker " DEEP 6 ". I simply used a frustrum off the 6mm Remington " cone ", skewered the base diam..... and DEEP 6 practically designed itself.
Deep 6 has the same long V-L-D friendly neck the 6mm Remington has, and the same easy-to-form
26* shoulder angle. That shoulder angle results in a lot of powder space contained within the shoulder area, while the long neck keeps the powder combustion " turbulence point " inside the neck; to aid in longer barrel life.
I case form with a stock ( LEE ) 6.5 X 55 Swedish FL die that has its internals removed, to make the die open-topped. So... NO custom case forming die set required !
* I DO anneal new 7 X 64 brass, before starting the case forming process *
I also use a " perch " made with a .308 shellholder, and a 1/4-20 flat headed shoulder bolt w/ head diam < .466". The perch is snapped into the arbor of the press ( Rock chucker is what I used ), and press arm operated to advance the case up-into the " forming " die. Excess brass extrudes out the top of the die, as the shoulder is shoved downward to a lower point on the case sidewall.
Newly-formed DEEP 6 cases emerge from the forming die in near-net shape. Cases are rough cut-off for length, then detail trimmed to final case OAL desired. Cases are inside neck reamed and outside neck turned, to arrive @ final neck wall thickness and calibre ( 6mm ) desired.
I load / re-load DEEP 6 using stock 6mm Remington dies. So... NO custom re-size reamer to buy !
as NO custom re-loading dies are required ! I use a Hornady shoulder bump / bushing neck size die.
I have not had to at any point... FL size my cases. I seat bullets using a Hornady " universal-style " bullet seater. So... NO custom re-loading dies to buy !
DEEP 6 accuracy and deliverable energy @ distance are exactly as I wanted, and we're achieved while controlling wildcatting costs !
Since DEEP 6 is formed utilizing the bottom portion of the 7 X 64 parent case, the resulting wildcat cases are very robust. I have cases still in-use, that have over 30 firings on them.
I'll send along a pic of a DEEP 6 cartridge, which shows a Sierra 95 T-MK seated.
I have shot both IMR7828 and RL-22 ( mostly the latter ), but am doing range work lately, using
RL-23, RL25; and RL-26. Max load using the latter powder is 44.4gr, w/ powder right up against the base of the bullet. I want to use a temp stable powder that gives me high load density, safe pressures; and superb accuracy. I am using FED Large Magnum Rifle Match primers.
Pics are out-of-sequence, w/ initial case forming step w/ the 6.5 X55 , the " perch ", the
Rockchucker press; and a sample annealed 7 X 64 case shown atop the perch further down in the pic columne. I apologize !!
