Got to test fire my t/c pro-hunter 44mag 22" barrel today, chamber reamed out to 445supermag. These are my first reloading attempts & firing of the 445supermag. Date off 1 day in pic. Any estimated ballistics?
Anyone got Hornady,Sierra,Speer load data(from mfg. manuals) for jacketed hunting bullets? I only have Hor. abridged 7 edition & no load data for this chamber. Have found some data on web but hoping someone will share current load data. Here is a few pic's of groups, saving best for last.

Hornady Data with 296/H110:

240 XTP starting load 28.1 gr 296; max load 32.9gr.

300 XTP starting load 24.4 gr : max load 29.4 gr.

Top velocities listed for the 240 load is 1,500 fps from an 8" barrel and 1,400 from the same with the 300 gr. load.

My ledger lists 34 grs. AA 1680 with a 300 WLN at 1,450 and 30grs. AA 1680 with a 350 WLN at 1,350.

All loads are with Fed. 155 primers and Starline brass.

Thank-You HawkI for the data. Any data for Hor. 225-265gr flex-tips & 265gr flat-nose?
May have to get some AA1680.

Have a 12" T/C G1 Contender barrel (factory ported) that Bellm rechambered to SuperMag for me. Started by using H110, but the muzzle flash was too much for me. Settled on IMR-4227 and it was bearable. Gave up 100 fps IIRC.

My loads were from the Sierra Handgun manual. Would post them up, but I'm on vacay. The thing about 4227 is you don't really need the heavy crimp that 110/296 requires, so you can seat the bullets out further for more case capacity. Sierra tested with the Dan Wesson wheel gun and I'd guess you can load somewhat higher for your Pro-Hunter. The Starline brass is pretty robust.

So using IMR-4227 doesn't need heavy crimp? No need to crimp in groove for jacketed bullets? I tried a few loads of IMR-4227 in 44mag using 240gr bullets. Seemed like I needed to compress near max load trying to crimp in groove. Didn't seem better than H110. Haven't tried IMR-4227 in 445SM yet, may work better in the longer case. Use a lee carbide factory crimp die? Rcbs taper crimp die? AA1680 powder need med/heavy crimp in groove?

Not really looking for max. speed, tight groups is my goal. Don't really want to shoot heavy 300gr bullets though. Right now my 240gr xtp's are approx. .135 off lands. Not sure if crimping farther back(making bullets closer to lands) will help. May have to try if acceptable practice. I do want loads to fire properly from 20F-75F. Couple of my loads looked promising. Need to be very consistent loading/shooting.

I have some IMR-4227 powder to try, Hodgdon reloading data shows no loads for this powder in 445SM. May want to try AA1680 also. Have a box of old Hor. 265FP bullets also to try.

Would like to see the Sierra loads.

Thanks

Contenders dont need a crimp and crimping adds another variable to accuracy and ES.

Use a mag cap if your worried about ignition.

Round 2 update, reloaded some more rounds this week & here are the results. Have been using CCI-350 primers. Only partial sized cases, 1/2 length this time,rcbs carbide dies. Round 1 was full length resized. All shots fired at 100 yards again this week. I haven't cleaned the barrel bore since starting last week.

Here is a load copied from last week that had best grouping(last week), Med/Heavy roll crimp.

[Linked Image]

Next load using just enough taper crimp(rcbs) & IMR-4227 powder. All loads using IMR-4227 shot low.

[Linked Image]

Next 2 pic's with light roll crimp

[Linked Image]

Last 2 pic's with Hornady 265grFP, loads 2&3 were a little snug in chamber for some reason in first pic.

Here's what I dredged up from my Sierra Handgun Manual (4th ed.) and my reloading notes. Sierra used IHMSA cases and Fed 210 primers in a Dan Wesson 8" barreled revolver.

240 gr Sierra JHP:
33.5 gr H110 - 1,600 fps
31.4 gr IMR-4227 - 1,600 fps (accuracy load)
38.9 gr AA1680 - 1,600 fps

250 gr Sierra FPJ:
32.3 gr H110 - 1,550 fps
31.9 gr IMR-4227 - 1,550 fps (accuracy load)
38.7 gr AA1680 - 1,600 fps

300 gr Sierra JFP:
30.4 gr H110 - 1,350 fps
27.5 gr IMR-4227 - 1,300 fps (accuracy load)
33.9 gr AA1680 - 1,400 fps


My load info (wow - it's been 20 yrs since I shot this barrel!) I used starline cases and CCI-200 or Fed 210's. I tried Fed 155's, but finally went with the large rifle primer. I partially FL sized my cases (like you) just a little further than the base of the seated bullet.

265 gr Horny FP:
33.0 gr IMR-4227, SD = 2.075" (well out past the cannelure) This was as high as I went, but no pressure signs indicated in my notes.

300 gr Sierra JFP:
30.0 gr IMR-4227. Again, no pressure signs indicated in my notes.

Use my data at your own risk, but you've got a very strong action and I was not worried about going higher than Sierra's loads, especially when I was seating those longer bullets out past the cannelure.

Thank-You for the data MuskegMan. After a couple of snug chamber rounds with hor. 265FP I have de-primed/full sized cases again. Trimmed cases back to 1.6".

I want to see my sierra/240gr/32.5W296 load again, also may want to bump up to 33gr for 3 rounds.

I was not too impressed today with IMR-4227 with very light crimp. Taper crimp(just enough to eliminate bell at mouth of case) looked better. Do you remember what type of crimp you used with this powder?

I still want to get some AA1680 powder.

Easy,accurate,economy way to make starline brass accept LR primers? I don't have a lot of brass.

I don't recall crimping w/4227 at all. I'm using .44 mag dies which have a roll, not a taper, crimp.

Don't need to do anything special with brass. Large pistol and large rifle primers are the same diameter - 0.210" nominal.

Update week 3:
I have got brass primer pockets reamed/uniformed to accept LR primers. Have full length re-sized this week. Shot at a friends house today,100 yards again. Was hoping he had his Chronograph set-up now but he still needs to build a stand for it. I did wipe cloth thru bore twice before going to his house. All rounds had a Med/Heavy roll crimp. Didn't seem like light crimp worked too good for me last week.

These first 3 groups had about 10 minutes between groups. Shots were fired consecutively in each group about 1 minute apart. Had approx. 10mph crosswind. I didn't mark 1 shot in group C(right below lower marked C), I believe this shot took part of my A marking(on paper target) in that group out. Lowest shot of A group was first shot fired.

[Linked Image]

Friend got cold & went inside his house while I fired the next 12 rounds. He wasn't dressed for today's weather. He shot his rifle at another target in between my first 3 groups above. All shots were fired with about 1 minute between shots.

IMR-4227 groups:

Hornady 225grFT, I'm not sure which bullet holes are 34gr vs 34.5 gr.

i've shot contenders pistols in .445 for around 10 years or so, have killed a few hogs, a few deer, and assorted stuff with the round and it has worked well, though recoil is brisk. tore up a couple scopes on a 10" Tc which had no brake, and pulled a forend dovetail lug off the barrel when i put a pachmayr forend on it.

later went to a 12" Virgin Valley, and finally a 14" TC custom shop with brake, the last was considerably more recoil friendly.

[Linked Image]

about 3 years ago i picked up a 22" TC custom shop .445 carbine barrel, and have shot it quite a bit over the last couple years.

mine is throated long....gotta wonder if they saved money by only rifling half the barrel. wink

i experimented with 5744, Lil Gun, H110, 296, 1680, 4227 (both IMR and Hodgdon...still got a couple pounds of H4227). had better luck with 1680, and lil gun, with moderate crimps. never got great super great accuracy any lightweights, but 240 XTP's did OK, and also had fair luck with the hornady 265FNSP, Speer 270 gold dot, and Hornady 300.

with the long-ass throat, i seated both the 265FTX and 300gr XTP's out long by crimping in the bottom cannelure, and tried H4198, and Reloder7. the added case capacity seems to keep pressures moderate with slow burners and Reloder7 with the 265 FTX's is a magic combo for my tube.....loaded some test loads with AA LT30, but havent got around to shooting LT30 yet.

Charges of Reloder7 lighter than 34.0 still showed smoked cases, low pressures, but i worked up in .3gr increments, and at 34.9, found a sweet spot...continued up and worked past 36 gr, started seeing some pressure, backed down...settled at 35.0 as best for my barrel.

[Linked Image]

i really wanted the 225gr Barnes XPB's at 2000+ fps to shoot well, but i never could get them to group like the Hornady 265's. The 265's also work well at those speeds, when they run into stuff......my 2015 buck, taken with the .445 SuperMag carbine...

[Linked Image]


The hornady 265 FNSP's seem more solidly built and plow through more meat than the FTX's do. The 300gr XTP's seem to open pretty quick but have enough mass to penetrate well. Bought some 300gr Nosler JHP's to try but haven't shot em yet.

i had better luck with rifle primers as a whole, and dont shoot pistol primers in mine any more. have shot about 200 rounds of the hornady 265 FTX since finding that combo, still shoots great, no issues. the stuff i was shooting might be hot in your barrel, so approach those with caution....

will dig through some loading notes and see if anything else comes to mind.

Regards-

G~

Congrats on a Great buck last year FyrepowerX!
Thanks for sharing. Target posted shot at 100yds? How many bullet holes in target(hard to tell)?
