I found data on loaddata.com using IMR 4320 using a start load of 34gr .....on anything except 180gr and up that uses 35gr to start. this opened a whole new arena of shooting for me and my dads 280 Remington....now my favorite load is 34gr of 4320 and 174gr FMJ it shoots 3shot groups of 3/4 inch at hundred yards,and my 175gr round nose do better than that!!!...not bad for a worn out barrel.
how to SLOW a bullet down
- Thread starter crustyrusty
- Start date
thats why In my opening statement I was looking for a really sloooow powder,, full case, and good ignition and slow bullet speed.... but i have discovered powders that work in low densities faster burn rates quicker pressure spikes and faster powder burn by the time bullet is down the barrel say 15-18 inches... all conducive to good accuracy.,,too. so i have now used H4895, and IMR 4320 so I really want to try Hodgdon US869 and see if my theory is correct,, slow powder light bullet= slow velocity
It works just fine...paper and experience do not lie. . What evidence do you have to make your claim ?
Quote...All joking aside do not compress trail boss you you will change the burn rate I am sure.
Do you have first hand experience with this claim ? If so what exactly did you find ?

you know whats really nice about reloading? discovery!! learning what a powder/bullet/barrel combination can do and can't do.. its the can't do that I find the most rewarding.. because it means your on the right track for your intended goal and your not guessing "what if"... so for all of the failed loads I feel the most enjoyment because I proved a point to myself that that Idea just didn't work the way I wanted it to do.. so I move on to the next great Idea and see where that ends up..because the more near failures and outright failures are so much more meaningful of a tool of learning, it makes the rest of the Right Stuff true ah haa moments.. so when other guys have something to input you betcha I listen very carefully.....then I compare notes to what I have already done and where I am headed in my research...the nice thing about reloading there are now like 165 powders (in the burn rate chart)to choose from. primers,, small, small br,,small magnum..small pistol,,large rifle large magnum large BR large pistol..........bullet availability is threw the roof small,medium,medium heavy ,heavy and super heavy..... the combinations are staggering. I dont do math but the total combinations have to be in the thousands... I will have lots of learning in my future and I hope I have many friends willing to give me suggestions to try to make a better round for my rifle... Rusty
Rusty, from a guy that's had the same negative effects from recoil that spoiled my accuracy for decades.
Like you, a 223 taught me to shoot well again and the things I learnt about my own shooting, some with the help of others that visit my private range, has me shooting similar groups with all my rifles under 1/2 MOA.
Once like you I loaded light but now never as I want confidence that me and my hunting loads can perform.
Tough as we think we might be the modern lightweight hunting rifle will beat you about on the bench and that alone will have you holding it too tight where you'll have less trigger control. When I'm shooting less I have to pay more attention to my setup on the bench, rock solid rests and additional padding.
And if you shoot from the bench with a bipod and not hold the foregrip you're gunna get beaten up more.
I've seen many a young shooter get bashed about to the point they can't shoot for shit and when possible stop them from making the same mistakes that take years to correct.
Shoot well.

Howdy !
I’ve had both reduced loads of a suitable powder and use of s-l-o-w powder and high load density methods work in my sEarch of highly accurate loads.
In my Marlin M-336 XLR .35 Remington I had great success shooting a reduced load of SR4759, and the comparatively light Remington .35cal 150PSP. Reduced H4198 loads also have shot superbly under Cutting Edge 150gr Raptor’s.
In my wildcat “Deep 6” ( 51.2gr H2O capacity ), my best accuracy has come from using a very nearly full case of RL-22. Velocity is notably lower than what could be expected from use of a faster burn rate powder ( under Sierra 95 “Tipped” MK. That is not an especially light 6mm bullet at, it I still fells the loads bears-out the concept of slower powder use.

Sorry, I wasn't clear. I meant the "under-loading will explode your gun" thing.
OK I understand now now . Thanks
It wasnt mentioned but there is also an ugly potential when using a mismatch of burn rate and cartridge , bullet weight. Especially in colder weather the slow powder can fail to fully ignite and leave you with a stuck bullet. Now thats not a pretty picture. Im not saying this will happen, but I'd think it is a potential result. I have had this occur in revolvers in very cold weather, using the proper powder, charge weight, bullet and crimp. The primer being not quite hot enough for the occasion. The primer just isnt hot enough, and the powder never gets enogh pressure and heat to complete combustion. Would be the class of a "misfire".
Just went to my Speer reloading manual. Turned to the section for the 280 Cartridge, where it lists loads for the 110 grain bullet. They offer 11 loads in descending order from fastest fps to lowest. The last powder is IMR 3031. Its start charge or lowest charge is 44.0 grains of the IMR3031. Muzzle velocity is 2814.
You're all done. I don't know what powder you were using to obtain 3,100fps but by using 44grains of 3031 you reduce the fps by almost 300 fps. Just follow the book, the recommended powder and the recommended charge. This is as straightforward and basic as it comes, just follow the printed data. Simply follow the book guidelines and your safe.

yes sir very much so I have become a better shooter for it!!! even my full power loads don't seem so harsh!!
This is something I never really understood until recently.
The more time we spend behind a rifle our muscles become better trained to manage the recoil. Still we mustn’t let a rifle hurt us so some trigger time with padding can help the body to better relax and yield to recoil instead of fighting against it.
With some little practice the recoil of full power loads becomes very manageable whereas once it was to be feared unless shooting offhand.
Sounds like you’re already reached that point.
Yeah I think I have!! recoil doesn't seem to bother me so much now (thats after several hundred rounds in just the last 2 weeks) I can now fire the rifle without closing my eyes, i can squeeze the trigger, not yank it, and I baught better earmuffs toboot so sound isn't so harsh as well... .my .223 is still my favorite platform to shoot but my 280 with 174gr FMJs at 2400fps is a close second.. so I am now moving on to movable ap500 steel targets and off-hand shooting.... this is gonna really be a challeng! but I am up to it!! I just love the sound of steel ringing in the air its just cool as all get out!!
Now that I have my 7MM Bench Rest rifle and with all of the load development that I have done with it using 100grain thru 175grain pills recoil has become a thing of the past....even the 175gr pills launch so smoothly that I enjoy those rounds as much as the 100 grainers...amd my ability to shoot freehand has gotten better and
bench shooting is getting better as I upgrade my equipment,, I just shot my first ever 100 yard target with all three bullets touch to make a perfect cloverleaf....if i measured correctly it measured 5/16 inch with a tape measure the load was 145 gr speer spbt with H-4895 so I guess moving to a smaller more gentler cartridge
was a wonderfull move for me to make.....hopefully this will translate over to my 280 Remington when I get ready to shoot it this spring cause it has a new barrel to break in with a custom match chamber to boot

I've messed around w IMR 4064 in the 308 win. using 125 gr. sierra. Found one load at about 75% of the Max listed that was very accurate to 200yds. I've tried downloading to 65% with 4895 powder. The rifle likes it but you may need to add drier lint [cold weather shooting from a tree stand/downhill] or Kapok as a filler...mike in ct
