Getting ready to order a 357 maximum barrel for my contender. Which would be the best route to go on the barrel just let MGM cut the chamber while they build the barrel or have it shipped to Mike Bellm for his famous chamber cut? I talked with Marty at haus of arms he suggested letting MGM do all the work for warranty reason. It will be feed a mix of bullets and some of those nasty J word bullets. Mostly plan to deer hunt with it and use it for range time with buddys.
MGM all the way unles Bellm has a barrel ready to go. I had Bellm rechamber 4 barrels for me, they all shoot better than I can hold. I have 2 barrels from MGM and they are very well made and chambered. Todd/3leg
I was going to have MGM make the barrel but just have them send it to Bellm for the chamber cut.Quote:

One of mine was done by Mike Bellm; shoots great.
What is the famous Bellm chamber cut?
I have quite a few MGM Contender and Encore pistol barrels and won't consider any others now. It seems like MGMs are chambered with minimum dimensions anyway.
If you had the opportunity to speak at length with anyone at MGM they will tell you that Mike Bellm showed/trained them on how to cut the chamber on their 357max barrels. You'll find that neither Bellm nor MGM has nothing but kind and flattering words for each other...ie, they're as thick as thieves. There exists an entire community out there that works on TC products and does quite well at it. There's another gentleman out there who customizes TC forearms so that they don't touch the barrel to enhance accuracy. I have bought frames and barrels from all three of them (Bellm, MGM, and Haus of Arms) and they're all good people to deal with. The only caution I'd give you is to NOT let MGM talk you into getting a 1:20 twist in your 357max barrel. They really push them hard when you buy. I suspect they got the deal of the century when they purchased the barrels and that was because they were in 1:20 twist. They'll tell you that they shoot just as good if not better than a 1:14 or 1:16 twist with heavy bullets (180g and up). That is definitely NOT TRUE. Neither Bellm or Haus of Arms pushes the 1:20 twist in their barrels. I've had custom guns built over the years in 357mag and max, and always got superb accuracy out of them in 1:16 twist. I let MGM talk me into the 1:20 and I have two pages on a spread sheet showing all the different bullets, powders, etc and the resulting groups. I have exactly 1 load that is marginally acceptable with a 180 grain bullet, and one only. David White, who also specializes in 357max rifles concurs with my findings. It's possible that your standards/expectations might be satisfied with 1.5-2.0" groups at 100 yards, but I find that unacceptable. My Low Wall would shoot numerous loads of heavier bullets under an inch...and that's five shots, not three. Just make sure you get a barrel with a faster twist from MGM or go to Bellm or Haus of Arms and get one in 1:14 or 1:16. I don't think either of those two even carry a 1:20 barrel for that cartridge. Good luck with your new barrel.
NSB thank you for all the info and taking the time to share it with me. My studying on 357 max had steered me away from the 1:20 twist MGM recommends. NSB do you have any suggestions on barrel length? I'm lean toward a 20" barrel.
My barrel is a 24" heavy factory contour. For me it balances well for off-hand shooting. If I were to get a 20" bbl I'd get it a bull barrel to keep the weight the same (or very close). Length wise there's no advantage in getting anything longer than the 20". If that's what you want, I think it's a good choice. You're likely going to need to have your forearm modified to keep it from touching the barrel. Contact strattoncustom.com if you want to get that done. His work is excellent, his prices are very reasonable, and his turn around time is very, very prompt. He's located in the same area as MGM is. I think he used to work for them before they were called MGM.
20" bull barrel with 1:14 twist was my plan for this barrel. Just wasn't sure if I should go with bellm cut chamber or MGM version.Quote:

Frankly, I have no use for Bellm, after he sold me $$$$ worth of parts and springs for my Gen 1, which did absolutely nothing to cure my light strikes problem. Which turned out to be the only spring he DIDN'T have me replace: the one which retracts the hammer block slide when the set trigger trips. Simply stretching that spring a bit to increase the preload solved the problem. Monetary cost: ZERO.
I am now cured of the T/C addiction, so have nothing else to say, except that I had Dave Manson grind me a .357 Max reamer with a cylindrical seat and the proper pilot diameter for about $10 more than Bellm was charging to ream a barrel.
