I just ordered a 357 max reamer and 100pcs of brass midway didn't have any 180 xtps in stock so I didn't order bullets hoping that ill get good results out of the 2 options I currently have.... So if I can't get the .358 200 ftx to expand still what would be a good velocity to push a 180 wfn for deer? I can probably push them over 2000 the way I load so any velocity is about doable... Just looking for some input I've never used cast on deer... In sure I can expect to break both shoulders am I correct? Thanks guys

At 2,000 fps you are way over driving a hardcast bullet. They work best when they maintain their nose integrity and don't need to be pushed hard to work well. Having said that, it may not matter on whitetail as they really aren't that hard to kill and they are lightly constructed. Swift A-frame would be deadly at those speeds as would the Barnes XPB. I don't have a lot of faith in XTPs and that really might be overtaxing them as well. JMHO.

I really want to try the a frame just with 130 dollars already into it I can't afford another 50 right now.... There's a guy who did some expansion testing with the xtps and they held together at velocities I couldn't believe.... That being said im really hoping the FTX works I think I can probably get it close to 35 rem velocities... And I didn't plan on pushing the cast that hard lol just saying I can... I was thinking 1200 would probably be getting close to the limit

I killed a buck last year with a 180 xtp and it did really good I figured they would be fine on whitetail but I don't want to go under 180 with them either

Just curious, what are you rechambering to 357 Maximum?
I have a CVA Scout rechambered to Max, as well as an MGM 13" Barrel for my G1 Contenders.

I have worked with 1680, LilGun, AA#9, 300MP, and H110 in the 357 Maximum with 180 XTP's. In a G1 Contender you will probably hurt the frame with a very steady diet of loads much over 1900 fps with 180 XTP's. I got to 2000 fps with H110 walking my loads up 1/2 grain at a time. I backed my load back down to 1850 fps. I had three reasons, ONE recoil above 1850 would be a little more than the wife would enjoy. TWO I am pretty sure that 1850 fps loads of H110 will not hurt my G1 Contender frame. THREE would be Brass Life. My 1850 fps load does not loosen up primer pockets or cause any other brass failures with multiple reloadings.

My hunting bullet mold is an NOE 360-180 WFN-GC. This bullet mold has 2 crimp grooves like the 180 XTP. I seated them long just like the 180 XTP to maximize case capacity. I have not worked with them a lot so far. My notes say that I started at 20.0 grains of 300MP for 1790 fps up to 23.0 that averaged 1968. No mention of cratered primers or sticky extraction. This work was done with my MGM barrel, which I believe has a .358 bore. It did not like my lead bullets very well. I got a larger bullet sized die but I have not loaded any of the larger diameter bullets for the MGM so far.

I shot up the remaining cast bullet loads in my Scout with a .357 bore, and it liked them just fine. No idea what I had them loaded with however. I am using White Label "Carnauba Red" in the Lube Grooves, and then Tumble Lubing with Bens Formula Tumble Lube (The Recipe can be found on the Cast Bullet Forum).

I really need to build another Fackler Water Box to test some bullets in. I would be tempted to build one that would use 1 Gallon freezer bags, and do my shooting at 100 yards to get the Impact Speed adjusted for an average deer shot. Using 1 Gallon Bags will give some latitude on alignment at distance. I have the multiplier to convert Water to Ballistic Jell results. It would be good to know just how far bullets penetrate, and what the bullets look like when it ends it's journey.

Its a contender g1 frame im getting 1800 out of 180s and 2000 out of 158s and I don't feel im really pushing the envelope... The 200 FTX load I used before got sticky on me.... I don't crimp anything cause mike bellm said not to bother lol... I've got a few loading manuals that show 180 and 200 grain loads around 1850 loaded long and they are only showing 35,000 psi on those loads... That's a full 20,000 psi less than the 223 with the same diameter case head runs... And its safe at 55,000 in a g1... Mike bellm said load them till the primer starts to crater and then back off just a little bit and that's what he considers a safe load in the contender... The data I have for aa1680 in a 12.5 inch contender shows 30 grains for 1837 fps at 35,000 psi and mike said 55,000 was the safe limit

Should have my reamer and brass tomorrow so ill just have to get out to dads to use the lathe to make sure its good and centered.. Should I clean up the crown? I've heard that some t/c crowns aren't very good it looks fine but I was wondering if I should go ahead and clean it up while I had the scope and bases off it?

Well got it done. Current load is 21 gr lil gun with a 200 FTX seated at 2.500 inches at 1800 fps. Cases fell right out and there was no primer flow at all im pretty sure I have some room to step them up I just ran out of time. At 50 yds it was putting 2 in the exact same hole it was hard to tell there were 2 bullets through the same hole they were so close. They sure look impressive loaded that way. Even more so in person
