I’m looking for all the powder options that I can try to find to start working up a load. I have a lot of powders already but mainly slow burning magnum powder so I need my options. My rifle is a savage large shank action with a hanks prefit 1.120x9 taper to .700 at 26” using HIS ignition and standard modules. The barrel has a 50gr chamber and the 9/16s breech plug. Smooth sizing. I bought and built this rifle with the purpose of using blackhorn 209 as in utah I have to use in during muzzleloader season but want to also see what I can do with smokeless since it is capable. Safe loads with any given powders would also be a huge bonus as I’ve searched to pages high and low and get some answers but not everything matches up with what I have. Also might try some lighter Bullets but don’t think I will go any heavier with my build Thanks for any advice or pointers

Your large shank remage is a bonus but be cautious on pushing it like some of us that have 1.250” shank diameters. I have some friends that push theirs w similar to yours and no issues -yet. I don’t like shooting next to them.
Your bullet weight of 275 is in a crossroads for the use of duplex loads using a fast booster to ignite slower magnum powders. Members have used slower powders but have large powder chambers and barrel shanks above the 1.250” range. Your powder chamber size is optimized for faster powders. Sew and Hillbill are good sources for load info.
I have tried a vast variety of powders from fast to slow with 275/312/325/350 in my heavier built .40 and also blackhorn 209 which you have asked about in another post. PM me if you want some info as my list is really long.
This thread contains some good powders to use. I really don’t think that slow magnum powders will work well unless you use a booster - JMO
Fouling and getting the next round down the barrel with a .40 requires a clean burning combo - cleaner is better. Or full sizing like some that are having great results.

Please list what powders and bullets you have available. I’ll get back with you. Anything other than 275 AM, which is ok.
Sometimes, with a 40, you may need to brush in between shots and be willing to accept that. My best loads are that way although I’ve gotten more powders to test. FWIW, it’s hard to get cleaner burning powders than VV powders.

FWIW, it’s hard to get cleaner burning powders than VV powders. I have no other Bullets at this time. I have just started with 40 cal so I don’t not have a stock of bullets to choose from. Willing to try just about anything for bullets. Started with the accu max because of BC I am looking to have an effective blackhorn 209 load for deer and elk out to 500 yards but the smokeless powder shooting is more just for fun and learning with my gun so I am open to other bullet options although it would be nice to use the same Bullets for both. I currently have h4831, 4350, 380, 110 us869 titegroup. IMR 4350,4831 4895 4955 8133. Rl19,22 23 10x and very small amount of RL15. |

H4895 is a very commonly used powder for 40 cals. 70-72gs should be very safe. That’s for H, not IMR. H & IMR 4198 can be used virtually interchangeably. 4895? I suspect so but hopefully someone will confirm.
4831, 4350, and any others this slow or even nearly this slow are too slow. 110 is too fast. Though they are excellent powders, I have little experience with RL powders but many or most other smokeless ML shooters have. Hopefully, someone will chime in.

IMR-4895 works Start at mid 70s and ease up Don’t go much above 80 Try with and without wool wads
I have also used VV-540 with the 275s again, mid 70s and ease up, don't get above 80 Again experiment with and without wool wads
The 275 Accumax is a very accurate bullet, I have shot it several times @ 1000 yds with great accuracy and every where between. I shot my best 300 yd group with the 275 and 80 grains of H-4895, .220 if I remember correctly.

Does anyone have reduced loads for the 275 AM or Fury in the 40 ?? Maybe 2350 to 2500 range with a Remange type contour ??

No experience with reduced loads for a .40 cal myself.

When you are doing load work up how do you decide to brush or not to brush when just starting with a new powder? I tried some accurate 2495 this past weekend and feel I wrecked my test due to getting a bullet stuck at 7” in my bore. Complete tear down of the rifle at the range. Ended up the powder in the threads. Did end up getting everything cleaned out and testing more loads brushing between shots but I’m looking for a clean load to shoot multiple shots with out brushing. I will retest again to confirm my finding. Gun shot very well but I want to test again more prepared before I share

try the 4895 with the 275, that is your ticket.
I won't shoot a powder that I need to brush between shots, That's just me personally, I know some do.
40s are very temperamental, to the point sometimes of being down right frustrating,take your time and have patience, it will come together.

Imr 4895 is in the next batch of test. Reason for trying the accurate 2495 is I have seen it multiple times on the shelf and seems like an un used powder in my area. Replacing my imr 4895 is hard with my current available market. I got some good results but my chrono was on the fritz for half my shots. Do you just live with the fact that when testing loads you might stick one? Or is there a way to navigate the guessing game |

Just make sure you are using a powder in the desired burn rate for the weight bullet you are using, you can get into trouble in a hurry with the .408 bore, it builds pressure really fast.
I have found that if a powder is dirty you are not burning in it's intended pressure zone.
Quick loads is an invaluable tool for trying to figure out what powders MIGHT work, the rest is in the testing.

Well after two range sessions with Accurate 2495 I feel it is a pretty decent powder for a start any way. All loads are shot from the rifle listed above. Safe in my rifle might not be in yours. I have been very careful in watching for any signs that show pressure and have had zero signs through both tests.
275gr Pittman. Wool wad. CCI mag large rifle A2495 smooth sized
First load of 68grs gave 2576fps attempted to load second shot and stuck the bullet at 7” complete rifle strip and removed the stuck bullet. Did not get every grain out of the threads of the breech plug so when the first charge of 70gr went down it was also dumped and rifle stripped again.
70gr load gave me 2607 and an error. I began brushing 3x passes with a nylon brush between shots from here on out. Felt the test was a bust so I was making scope adjustments through out the test
72gr load gave 2838 error 2849 group was 3/4”.
74gr load gave 2799 2797 2808 scope adjustments from 72gr to 74gr had not fully settled and wrecked this group
Test two this test was conducted with no brushing. Mainly trying to find out if this powder burns clean enough to be useful for my purpose. I’ve got tuning to do but this can be shot cleanly
74gr 2786, 2780, 2757, 2787, 2812
Group was 1 5/8” all loading was consistent
75 gr 2795 2813 2818
Pulled the 3rd shot as it broke
Group with flier is 1 1/2” loading was harder for 6” then smooth and consistent. Palm force then 3 fingers the rest of the wat
77gr 2881 2846 2867
Group was 3/4” all horizontal no vertical spread
Loading same as 75gr
78.5gr 2930 2945 2920
Scope adjustment was made between loads and did not settle til after 1 shot group 1 3/4”. I am mounting a better scope today as the current scope was mounted till I decided what direction I want to go with the gun.
All modules still have tight pockets. Primers still have nice round edges. None of the loads i shot gave me the feeling that I was at or over pressure. Recoil is not bad for my rifles current weight between 9.5 and 10 pounds. Upgrading the stock one day which will add at least a pound and then recoil will be very controllable
