i was going to with the 45 Colt in a 10" Contender barrel (either Bullberry, MGM or SSK) to hunt deer with next year. my dad (RIP) had a friend back in the '70s (it might have been in the early '80s) that had a TC Contender in 30 Herrett and he luved it. i was "thinkin"

that a 357 Rem Maximum would be great in a 10" barrel and then it hit me, 357 Herrett. i have about 400 pieces of 30-30 Starline brass (100pcs are for the 35/30-30) and i reform brass ('06 to the 7x57, 8x57, 9.3x57, 7.65x53...), which can be quite annoying, but i like it .the place i hunt deer is sorta close up, 60ish and under and i think i'll go with 2x scope. just like the 45 Colt, it will be a cast boolit only gun. i'll probably just size the 200gr RCBS fn gc to .359", but maybe i'll want something different, like a 180gr fn gc.

ok, now i am ready for comments and the Herrett and tell me that i need a 45 Colt or a 357 Rem Maximum.

Forming brass to 357 Herrett will be painstaking to get it right. The barrel needs a good snap to close right.... keep that in mind or you'll get misfires. Once you get the forming and loading procedure right, you will get sub inch groups at 100 yards and excellent kills with it. Go for it.

#1 I would opt for Bullberry. Nice work!

#2 The 35 Remington is the best of all worlds for a 35 caliber T/C. Having said that, the 38-55 can arguably deliver a tad bit more punch BUT the barrels will come with a .375 bore and not a .379/380 bore. I would opt for the 35 Remington. All of the internet negative comments about the 35 Remington in the T/C are based on folks who do NOT know how to headspace a 35 Rem on its shoulder. It requires meticulous care when sizing the cases to maintain proper headspace in the T/C chamber. Once you fireform, neck size only to maintain dimensions. Easy Peasy.

With rifle in hand, I confidently go forth into the darkness.

A .35/30-30 in the Contender is also a good choice and easy to load for.

I shoot the 357 Herrett and love it , I resize 375 win. or 38-55 brass and adjust dies to where the barrel just closes and very rarely get a misfire then neck size only , and shoot a 310 gr. paper patched bullet . even on first firing get 1 moa .

a 38-55 has a lot of nostalgic appeal ... but really should use a custom reamer ... i miked an original 38-55 chamber casting just today and it has a 0.390 throat !! ... can't bring myself to alter an original 1895 m94 tho ... need to just wallow out a 37 mold to a 39 ...

The .357 Herrett should work very well since it was developed for Contender use and usually loaded at lower pressures so it lasts a long time if headspaced correctly. 30-30 Brass is plentiful and cheap (pick-up brass can usually be found). 357 Maximum and .35 Remington brass is frequently pricey and/or hard to find. The .357 Maximum would probably be the better choice for an area requiring straight-walled cases for hunting.

then it hit me, 357 Herrett.

Let me know if you need dies. I came by a set in a trade and have no use for it.

My 2 cents. I have all the above Contender/Encore barrels, and then some.

BUT, my favorite Contender deer hunting cartridge for woods ranges is the .375 Winchester. Full loads using 265 gr Lyman/Ideal design cast bullets. Accurate and very effective. It would also be legal for those states that have a problem with bottle necked cartridges. NO hassles with case forming: just order from Starline. My barrel does have a muzzle break, and even then you know you fired something.

my tc encore with a 23" MGM barrel in 444 marlin with a whole host of cast boolits will agree with you. i would take a 300gr fn gc that goes 1624fps and it would kill deer just as a 265gr Hornady fn with a max load, but without the bloodshot meat.

i hunt in swPA and there is no problem with bottlenecks. i have a 14" Contender factory muzzle break barrel that i just abhor. it was given to me by my dad (RIP) and i don't like the muzzle break!!!

Todd,

The brakes do raise my dander a bit and necessitate muffs but oftentimes keep the recoil manageable and serve to extend barrel length enough to allow use of a buttstock.

I recently acquired another 357 Herrett barrel and realy like it's performance.

I actually sought it out to obtain the engraved rings as I find them to be a fading novelty in today's shooting sports equipment.

The .357 Herrett is a fine hunting cartridge, and I'm sure you will enjoy it. Yes, the cartridge case does require a snap fit, but this can be overdone. When I first started playing with the .30 Herrett and the .357 Herrett, I was having trouble getting good accuracy. I accidently ran into a fellow, who would in the future of that meeting, become very well- known and respected Contender expert. His advice was ease off a little on that snap fit. I followed his directions and much to my surprise, I instantly got the accuracy that I was searching for.

When I started out, I was reading the case forming instructions in the Thompson Center reloading manual and I durn sure had a snap fit, and it was a little exaggerated, the result of that was, no acceptible accuracy. After talking to Mr. ----, and following his advice, my problem was solved. That advice not only affects contenders, it effects any cartridge that has the case head and the shoulder jammed too tightly between the breech block and the shoulder of the chamber.

In a weak moment, I sold my .357 Herrett and have regretted it ever since. My advice is, stay with the Herrett and don't go to some other contender cartridge. I liked the .357/44 Baines and Davis, but not as much as the .357 Herrett.

mr. mashburn ... snap fit ... i wonder if that perfect snap fit conundrum ... is related to the funny impression that fire forming loads can seem to shoot better than the perfectly formed match loads following ... ?? ...

my serious bench rest buddies have mentioned this also ...

truth or myth ??

maybe we should try breech seating .... ... oh wait ... ...

Hello Ken

I'm glad there is at least one person out there, who has knowledge, of such things. It is definitely, a factor in accuracy.

There is also one person out there that doesn't have a clue what "snap fit" is. Sounds like what the hero does in the movies by flipping the cylinder of his trusty model 10 with a grim look on his face -- but I'd guess probably not.

The "snap fit" thing?. At one time, the recommendation for reloading for a T/C Contender using a cartridge with a shoulder was to set the sizing die to move the shoulder back just enough to allow the action to close with a firm snap to obtain optimum headspace and minimize case stretch. The problem with that is that small variations in the exact shoulder location could result in excessive interference and create variations in the locking bolt engagement which could prevent the hammer block from moving out of the way and cause erratic ignition or misfires. Mike Bellm's tech support articles now suggest setting the shoulder back far enough to allow a 0.001"-0.002" gap between the case head and the standing breech which can be checked with a feeler gage and seems to work well. FWIW, the old benchrest shooters at the money matches at the local range use "bump dies" every few firings to move the shoulders only back about 0.002" to minimize variations in the preloading on the locking lugs in the bolt guns. The AR shooters also do this to ensure that the bolt lugs reach full engagement when the action closes. That seems to be a concern mostly on the Creedmore and similar very high pressure rounds with largish case head diameters.

_______________________________________________________________________________

In testing the T/C Contender, the uniform closing of the breech was the most important attribute for accuracy (uniformity). Being able to press the barrel to lock with a heavy push and hear the click sound the same for each shot was essential. First moving the sizing die down enough to produce this uniformity with an empty case, then seating the bullet to leave a .100 witness mark on the nose of the bullet produced the greatest accuracy in my testing.

I have never thought of using a feeler gauge, this is a good idea.

Note: This was not slamming the action shut, but firmly pressing the action down until you hear the click.

Hello Hornet,

Mike Bellm is the man that I was referring to in my post, that I described as, someone who would become famous in the contender scene, in years to come. That was many years ago. Thanks for that notation in your post.

I guess that is a dig on me. I definitely know what a snap fit is, and so does Mike Bellm, who is the man I was referring to in my post.
