I also want to congratulate u Bill on ur accomplishment. U are a very talented & determined individual. Some time ago u set out to build a mzl capable of shooting targets at a mile. I think u are there. As a matter of fact I think u would have shot the mile Thursday evening if the range would have had a target up at that distance.
Yes, some probably think what u are doing isn’t practical and for most that’ true I guess but for the guys that are driven to pursue such a thing we understand and appreciate it.
In the end we all benefit from the knowledge that is gained from all the hard work ,the testing and new products that have come along in the last few years. It’s all because someone like urself had an idea and went to work to make it happen.
Good job ole buddy !

Jeff Fisk proved that good accuracy at extended range is possible with the .40 bore over a year ago with some incredible shooting.
It just takes some time and determination.

N530 powder with kyles 250 at 100 yds. More accurate than h4895 but fouling after 10 shots. I like point of aim that changes with cold bore and powder change Attachments:

What is the recoil like on these 40's shooting at 1000+ yards?......compared to say 45's with 70 grains of H4198 with a 300grain bullet?

That greatly depends on the gun, my gun weighs 21 1/2 Lbs, not a hunting rig for sure, even at that weight and a really good brake you definitely know it when it fires.
Probably not any worse than the load you described in a 10 lb total weight package ( pretty light gun) like I have built lately.
I fired 16 shots Thursday evening without a sore shoulder and no real trigger jitters on the last few shots.

I like point of aim that changes with cold bore and powder change The .40s do tend to build fouling much more than the .45s, it just takes time and loads fired to find the sweet spot with a given bullet/powder combo.
I have found loads that burn very clean but it takes some trigger time.

I’m currently testing 123-125 grain of N560 and 350 aeromax, Full forming the 350,s I had 30 minutes yesterday to test … I almost always pull plug run brush through to take out crusting,especially in 45. The FUll form for what ever reason totally change the fouling because I just loaded the gun hoping for the best that I didn’t get bullet stuck …It loaded as if I had shot couple times.. had zero fouling in , no copper is building up no nothing…
This isn’t the first time I’ve noticed this Full forming…in the .40 caliber.
In early spring i smooth formed with 124.5 grain of IMR7828SSC and about 8-10 shots are all I’d get before having to clean the copper building up last 6-8 inches of barrel… Full forming does something to it ..
The rifle had sit since last Sunday till yesterday..

And by the way these loads are safe in my gun even according to quickloads..
May not be safe in your.40 caliber

To Add:
Any time we post a .40 cal load of any kind keep in mind the guns we are using most likely are not a light weight hunting rig, before thinking about using these loads or some variation of them consult the guy that listed the load to see if it might be safe in what you are intending to use, never assume anything with the .40 cal, It will bite you if you don't stay on your toes.

I have witnessed a .220 group shot at my range with a 275 accumax and H4895 ..at 300 yards on a not so calm cold day before Ohio gun season.. The lighter Bullets seems to be more accurate. I love to shoot and love a good challenge so I’m sticking to heavy.. Did you find out what load that guy was shooting by chance ?? What was the gun built like ?? |

thought I would post some pictures of recent stuff with my big gun. first target is @ 1000, 2nd is 500, both need to rotate right (top is on left)
far right is first ladder test with VV N-560 powder, 1st pic is last ladder test I did landing me @ 132, test distance was 104 yds.
for those wanting to fine tune loads this is one good way to do it, as you can see I hit a node @ 127 & 132, as the charge goes up notice how the group spreads and then closes back down. On guns with a big charge of slow powder most times you will have a low and high node, guns with lighter bullets and faster powders? maybe not before you hit pressure.
last picture is at 1603
not great shooting but it shows some promise.

shot the big gun again last night using a different lot of powder and the same charge was averaging 3305, group opened up some, not bad mind you but not trying to go thru the same hole so next time out I will back it off 2 grains and try to get back to 3260 node.
after more than 50 shots without cleaning this load slides down the bore like butter, I have yet to do a thorough cleaning since I installed the barrel, I might clean today and start over just to see how the load reacts to a clean barrel and to see If I have any copper present.
A note of caution to those working up loads, when you change powder lots your speeds WILL change, especially when you are shooting high volume loads.

Cleaned the 1760 gun tonight, easily cleaned and 0 copper fouling, I had only brushed it out and a patch prior to trying this new load about 55 shots ago, I'm happy so far with the way it shoots and burns, loads as good on the last shot as it did on the first.
Anxious to see how it does on a squeaky clean barrel.

How much interest is out there in the .40 cal info???
in specific: powders tested per given bullet weight My information will be limited to these bullets
273 Hammer 297 Hammer 275 accumax 300 Accumax 325 Aeromax 350 Aeromax
To some extent I have kept records for the last 3 years of testing .40 stuff so I have some info written down, while they will not be recommended loads they will be true to life info of my findings in the .40 bore of which myself and several others are still experimenting with to this day.
It would take some time to put together and would likely need to be separated from .45 cal info altogether. Thoughts??
Bill i take it then youll eventually be moving all the 40 related threads here into the 40 forum ?? This idea is a good one for this seperate listing to condense it into its own area . Good job Bill !!! I hope the 40 boys will all freely contribute once we get used to this new area !!! Sew with the decades of time youve spent with a 40 im looking forward to your findings on many things !!! What you write is always rich with experiance and enlightening . I thank you and all in advance especially for the hunting loads findings as i believe this will be the majority of a 40s use . I believe your input could really add Alot here with years and years of 40 experiance !!! My route to a 40 of sorts was a Super 91 White in 410 from a gun show for $150 , pristine at that . If youd had chosen the 40 route back then Bill in your smoker days that alone would have converted you !!! Doc Whites ballistic tables compared tell the tale well . Michigan game ranches that saw for themselves on deer the difference of 410 vs 451 bought every 410 Doc had along and ordered more . Old school smoker or not i will Never sell "Mighty Whitey" !!! I do really like my 45 SML but im very much looking forward to the 40 being done by summers end hopefully . This is what ive been told anyway for a barreled action . Waiting on a different custom straight 3.2" bolt handle and then it ships off . Im very much looking forward to this muzzleloader !!! I will still have some stock work to do and a local black oxide of the bolt . Hopefully someone will share my pics when its done . Buckstuds and Buckeye68 thanks for the load info in previous threads with a 250gr bullet . These loads will be my starting areas to begin . Our rifles will be very similar and your loads look Awesome !!! Hillbill your 275gr load does too !!! Perfect medicine for farms i hunt . Thanks for sharing them !!! |

I will not be moving all the .40 stuff here, it's too scattered and would be too time consuming to do so.
All .40 stuff from this point forward will be placed here.

I also am one who has been and still experimenting with the big .40 caliber and mostly large doses of slow powder… Having some great days and some ready to kick and throw stuff days not to mention, I do feel we are starting to narrow it down to what these big guns are liking… some having great groups with RL-16 and RL-23 I’m experimenting with VV-N560 and IMR 4955 delivered tomorrow to test with the 350 aeromax.. But some have the 325’s figured out shooting.271’s at 400 yards and I am determined to find that holy grail load in the slow burn powder…When I feel I have it it doesn’t repeat next range trip for what ever reason… I do know we are really close to a set load from 3158 FPS to high as 3260’s.. which calculates from.625-.630 plus BC’s Incredible!!!!! Thats some fantastic info you listed. TY. I'm havin my 1st .40 SML built now. Brux 1.20 x 5 - .750 @27" 1:14T I'm planning to use 240gr Fury OT bullets & want MV's in the 2800fps range. Would 4895 or 322 be powders I should start out with? Or should I try some R16 or something else? Powder chamber advise to plzzzzz. TY |

My 40 cal 20" barrel gun has NO powder chamber. This was done to use faster powders with the 228 gr Pittman. It is easier for me to add a powder chamber later if I decide slower powders than H4198 are necessary and could benefit by using a chamber. I have another 28" barrel (no chamber) in the works to achieve 2800 fps and I think I can do it with the same 56 gr load I'm using in the short barrel and maybe a little more. I believe that's enough for 300-350 yds. Most deer shot are at ranges shorter than that. Guns can be made lighter, have less recoil and doesn't require a brake. Not necessarily fact, just my opinion...  |
