25-45 Sharps update and load development

- This is just an update on where I’m at in the pod development process on this. Answering some questions and general loading. This was a low cost build rifle for something to scratch that small quarter bore niche my father has. It’s meant to be cheap and simple. I’m using the components that are available right now and may have some more testing in the future. As of now we are honing in on a load with h335.

I am not a professional. Anything you see on this channel is strictly for demonstration purposes only. You should always follow published load data and manufacturers specifications. The things shown on this channel are my practices only that I have honed in on over the years with my experience with trial and error. Just because it works for me does not mean it will work for you.
I used 26 grains of Ram Tac with 110 grain Monoflex at 2575 fps, 117 grain Hornady at 2515 and Nosler 120 grain at 2475. The cases were full and slightly compressed. There were no preassure signs at all. This was fast enough for me so I did not push them further. I am sure you could get another 1/2 to 1 full grain in there with no trouble. I was using once fired Lake City brass.
So out of the 110 117 and 120 which round reaches the farthest? And which one is the most effective?
@@minhquinn439 the 80 grain ttsx has a bc of .316 and velocity of about 3000 fps. These bullets need around 2000 fps to expand which it should hit at around 350 yards. At 300 yards It has around 800 foot pounds of energy left. This is probably the best option for deer at 250 to 300 yards. Closer in any of them would work well the best bc was the 120 grain but because the charge was getting so compressed I could only push it to around 2500 fps. Which will give around 800 foot pounds @400 yards but the velocity would only be 1770 fps which may not expand.
@@bryanshull372 Yea that's why we need to start emailing ammo companies to ask them to mass produce 77 and 85 grain 5.56 and also mass produce 6.5 grendel and 6mm arc. the bc and effectiveness at range is phenomenal and very impressive.
@@minhquinn439 I already have 500+ yard rifles and never shoot past 250. That's why I wanted the 25-45 or a 6mm-45. I wanted 243 performance at shorter ranges and mild recoil. Since Midway discontinued their 6mm- 45mm uppers I went with the Sharps and have been very pleased.
I found Reloader 7 and H322 to be my best powders on 70g, 87g and 102g bullets... Drops an antelope in 1 shot no problem at 200 yards
I was watching this video again and saw something else that will bump up you performance on the 25-45 Sharps. I run cci 41 primers which are supposed to be a magnum. This has the effect of about 1/2 a grain of powder. Also you can cut some of the ballistic tip off and seat your bullets further out. Just like the boat tail, the ballistic tip has little if any advantage inside 300 yards. Dont be afraid of compresed loads. They are usually more accurate and will give lowes SDs.
I forgot to mention that my 25-45 sharps barrel is 24".
That helps a lot with velocity
The tests done on fps per inch is around 30
I do think that the Sharps 25-45 is an under appreciated cartridge. I have debated this with others and people often bring up how much better the Grendel is over the Sharps. In most cases the .264" bullets are going to perform better at long ranges than most .257" bullets. There are however newer .257" bullets that are on par with the .264".
Even Arne Brennan, the creator of the Grendel, is developing the 257 Raptor because of the many hunting bullet options. It will also use 5.56x45 cases. The neck however needs to be trimmed to allow the use of the heavier .257" bullets (keep OAL less than 2.260").
I like how easy it is to make brass for the Sharps 25-45. I simply decap the spent cases and run them up through the full length Lee resizing die and wet tumble them in a wet tumbler for 30 minutes. The cases have never needed a neck trimming. Neck trimming is my least favorite case prep activity.
The Sharps 25-45 performs very well with the factory load data using H335 powder. You should expect 2,800 to 2,900 fps out of a 20" barrel. Compare this to the Grendel with 90 grain bullets at ranges of 400 yards or less and there is not much difference. All of the 5.56x45 magazines have worked with the Sharps 25-45 including the Magpul D60.
I do recommend not buying the barrel from Sharps. I think you can get a cheaper higher quality barrel from a different source. I ordered a 20" nitrided barrel from Sharps about 2 years ago and they sent me a 20" barrel with a black oxide finish. I contacted them about it and they told me that they no longer had 20" nitrided barrels in stock and that they were not making them any more. I store my upper with the black oxide barrel in a climate controlled environment after applying a thin coat of oil and it still develops surface rust all over the outside of the barrel. The rust is easy to clean off and it does not appear to have affected the barrel's shooting performance. Nitrided barrels don't rust!
Check out the 257 ocelot by mdws it’s more for heavier bullets and performs better due to the case taper being blown out and the sharper shoulder design. I own the parent case 6mm mongoose and am pushing an 85gr bullet with imr4895 at 2830fps I. A 22” Ar platform loding them at 2.220”. I think the quarter bore stuff is one of the best hunting calibers period because it’s small enough to give you the speed but big enough to give you the stopping power. Check out my videos on the 25gpc. The 25cal is making a comeback for sure! And I’m not done near future I’m building a short action magnum in 25cal
Where else can I get barrels for the 25-45 SHARPS for an AR15? TIA
Xcaliber chambers them and custom order one through them. I think this one came from green mountain formerly known as black hole weaponry
The big advantage to me is that it uses the 5.56 bolt face instead of the weaker 7.62x39 bolt face. The weaker bolt faces had problems early on with breaking lugs. I think they have fixed that but I still prefer the bolt face as intended. Also in the reasearch I have done the 25-45 Sharps and the 6.5 Grendel are balistic twins with the same weight bullets. And I have HUNDREDS of 5.56 cases while the 6.5 Grendel ammo is hard to find. I could use 7.62x39 cases but I don't have any empty.
I ordered my 24" stainless barrel from Sharps and it is fantastic!
Would be nice if Barnes made a lighter ttsx for cartridges like the 2545
To me 80-90 sweet spot
25-45 Sharps bolt gun here 87gr of Rel 7 getting 2868 fps ES 18 SD 7 sub moa groups.
Have you worked up a load with a 100gr bullet yet
Have not. This is my fathers rifle I settled on the 70gr blitzking for him.
Reloader 7 and H322 work really well for me..
It just doesn't seem practical because there's 77 and 85 grain 5.56 that they need to mass produce because the majority of us aren't trying to pierce armor. Instead of trying to start a new caliber with the 5.56 casings they should neck down the 7.62x39 to 25 cal. That would be awesome. But then again I think 6.5 grendel and 6mm arc has that covered the problem there again is we can't find any ammo for those rounds and the ones we can find are the same price as 308. Wish people weren't so money hungry so those rounds get normalized and then up the price once there's a lot of people buying.
Like I said in an earlier post, the problem with the 7.62x39 size bolt face in the AR platform is that they have to hog out to much metal and it makes the bolt lugs weak and subject to breakage. It would realy ruin your day to have a bolt failure in the field looking at a once in a lifetime buck! So you could just get in the habit of carrying an extra bolt or use the bolt face it was designed for. The latter seems more reasonable to me.
