6x45 info

[Mauser78]

Hi Guys.

I am looking for some info on reloading for 6x45?

Any info would help.

Do you still get a round nose 100 or 105gr bullet?

What powder and load, Sonchem please.

I will be looking at about 2350fps with a 100gr.

The action is a Zastava mini with a. Truvello barrel.

Thanks

Seems this round has been done in some custom AR's. Sounds like an intriguing caliber. This is what I found out though. The 6X45 is not the round to shoot the larger bullets. The 105's need a 9 or 8 twist and be pushed closer to 2900 to 3000 FPS to go out longer ranges. It does well with the 65gr and 70gr if want to shoot heaver bullets then I would use the 243 with the 95's. The 6X45 is a 300 yard round and if you want to go longer then I just move up to the 243 Win, the 243 WSSM, or the 6mm Rem. This is from a quick internet search and read. If it is reality and you do want to go heavier, I would opt for the 6mm remington. Plus brass for the 6x45 might be a pain in the ass to find.

Love the velocity, but pressure is too high for long brass life. Also had to seat bullet out further. Low SD and good accuracy.

Hi 35Bore.

Thanks for the info.

Here in Sa we use it more for a bushveld caliber, up to 150yrds.
We used to get commersial amo in 100gr (actually it was only availible in 100gr)but it is getting very scares.

Brass is not a huge problem, i do have 150 emptys stamped 6x45 and 223 is easilly converted.

The other problem is normal 100gr spitzers is about 2mm to long for the magazine, round nose works perfect.

Herevare some pics of the gun, i hope.

Nice looking Rifle I like the Impala carving on the Buttstock.

Thanks Bob.

 

[plongeur]

Hi you can try 105gr Roundnoses from Steward Bullets I use 22gr of S335 in my Zastava,The number for Ken steward is 0728212102 If you want more info feel free to mail me on snellim@gmail.com ,\.If I really look for it I got an article with other loads for different bulletweights somewhere as well

 

[Mauser78]

Hi Plongeur.

Thanks, Ken is in Polokwane if i am not mistaken. Do you perhaps know what speeds you are getting with that load. S335 wil suit me since it seems that is the preferred propelant for my other caliber in want to load (8x60s).

Have you tried him for brass as well? I read somewhere that he does brass as well.

Thanks again

 

[plongeur]

I didnt load the 105's from stewards yet But with 100gr hornady RN I got around 2270 with 22,5 gr S335 .I was told to go 0,5 gr lower with the stewards since the bullet casing is thicker an hence the pressure will be higher.And yes he is in Pietersburg

 

[Mauser78]

Thanks I am in Polokwane as well. I used to shoot the hornady,s but cant seem to find it. Have been using New Generation Arms, loaded with 100gr hornady sp's at 2375fps lately but are not really happy with them. I do have a couple of rounds with Ken's 100gr loaded but they are loaded a bit to fast for me, but the results is a lot better than the NGA.

 

[Alexandro Faria]

Apologies, I know this is an old thread, anyone think that a short barrel 6x45 ruger #1 would be a good idea?? Would it let one possibly get a little more from the 105 gr rounds?

 

[Ray B]

I've considered the 6mmx45 and the .25x45 but mainly as an upper for an existing AR. I have not gotten past the deciding stage. Both are very good cartridges within their limitations due to small powder capacity, but for those states that require a minimum of 6mm bore size for deer, they have potential.

 

[Milehighshooter]

The problem will still be getting enough powder behind a 105 with the correct twist. There are plenty of 75-90gr bullets that are better suited. Sierra offers a few that would be great.

Really want one myself, probably on a Savage 110 I've got sitting around. Ive for several hundred 50-90 gr bullets I need to use up. Have a 243 for the several hundred bullets in stock that are over 95gr.

 

[HuntingGold]

I had a 6X45 built earlier this year. It was on a 700 action with a 22 inch barrel. I love the little gun and look forward to shooting it more in the near future. My gunsmith told me yesterday that he is so impressed that he is looking to building one for his daughter in law. I am developing loads for this gun now and plan to take it to RSA in May for testing. On the menu are Impala and Blesbok culls. I plan on testing a monolithic bullet and a Sierra Gameking.
