6.5 creed with 150g SMK

[FrankG]

I’ve only shot them out to 430 yards but the 150SMK shoot excellent out of my 6.5CM. MY barrel length is 23” and I’m pushing them an honest 2700fps. 41.5gr. Of H4350. Wade Stuteville put the barrel on for me and he has a reamer with a free bore length approx. .020” shorter than the Saami min. Spec. 6.5CM reamer. I can update that information later if needed.

Hoping I can get out in the next week or so and run them out to a 1k yards.

I don't think you'll find a better bullet than Berger 140 hybrids in 6.5 streetcred

Bbarber what powder and length of barrel to get the 150 going that fast out of a 6.5x47? I run the 130 Berger hunting at 2950 fps with 42.2 gr of H4350 out of a 26” Broughton. Not max in my gun but probably getting close.

H4350 and a 30” Brux, I was able to get it up to 2800 but about 3/4 of the way thru a 20 shot string I would start to get a slightly sticky bolt. There is a node for me at 2750ish, I’ve been running them at 2745fps there and have not had a single issue

Very keen to hear more info about your 6.5x284.
I am seriously considering chambering one to shoot the 150’s in Fclass matches.

What twist and land configuration are you running? What powder for what velocity?

Being in Australia I will have to wait for barrels but I want a 7.75tw 5R rifling and was hoping for at least 2950fps in a 30” tube.

Biggest issues I can see are keeping the bullet together during hot long strings of fire but still having enough twist for colder months here in Australia.
Most of my shooting is at altitudes near sea level.

I have run the 150MK in a couple of 8 twist barrels and it didn't work. I have other shooters that run in 7.5twists and are not bad. I went to the 7 twist to get ahead of the problems and it seems to be working very well.

I am fitting into an AICS type mag with an OAL of 2.92"... that is WAAAAAYYYYY short so my case volume is peanuts compared to a normal F class set up. I am running a conservative load of H4831SC for around 2750fps.... this is a honking long bullet and takes alot of case space when feeding from the mag.

For mag feeding and this bullet, I would go with a short magnum next time. I have similar useable case volume to a 260AI with a long throat. At least is seems to be very accurate.

Others who are running in F Open rigs have no problem getting into the 2900's with long throats and 30" barrels.

I really like H4831SC but other are running H1000 and also reporting very good results.

Is it better then a 284 in the bigger scheme of things?????? don't know but recoil is definitely less

Good luck with your project.

Thanks Jerry.

Yes at the lower velocities your running tighter twist seems fine.

I am wanting to find a node at least 2950fps up to 3050ish if possible.
From the reading I have done a 7.5twist is probably too fast for the bullet at those velocities and people have had blow ups on long strings of fire.

7.75 should be fine I hope.
The canted lands in theory should stress the bullet jacket less and hopefully reduce the chance of a blow up as well.

All done in theory, will just have to see how it goes in reality.

If this bullet can be pushed reliably to 2950fps it will compete with a 7saum in the wind as well as a mildly loaded 300WSM

The SAUM and WSM are my other cartridges I am considering.

I tend to agree with most who have commented. The 150 SMK has done well for me even with 8 twist. However, it does work better with velocity. 6.5 swede works well at 2820-2830 and 6.5 x 284 shoots at about 2930. Many on here have commented on the 6.5 x 284 update thread. After listening to those on the other thread who have much wisdom...if starting from scratch I would probably go with faster twist for this bullet and 2900 plus. For all four of my 6.5's nothing shoots as accurate at 300-600 as the 130 vld or the 140 hybrid. My intent for the 150 was 1,000 and further. At this point I give a slight edge to the 140 hybrid in the accuracy department but I can't knock the 150 at distance in the wind. Shooting long strings is an issue as well! I have not pushed them to the limit as others have.

All sound really good. My set up is slow... no way around it but it shoots very well. What I have found is that the 150MK is very sensitive to pressure and there is no upper node. When I worked up using a mid range load, accuracy was stunning... then I went higher and the loads just got worst and worst and pressure started to build.

Be interested to see how the slower twist might mitigate this. I am sure long throating and taking the OAL well over 3" would create more case volume to add more fuel.

But putting them through the same hole at 250yds seems more exciting to me then another 50fps

Good luck with your project.

In my LR plinking, I have pumped through 15rds in one string and 20 rds in another... no problems and all bullets made the trip. Barrel was hot but not insanely so. Accuracy on last shot was excellent.

What twist barrel are you using?

1-6.75 is my twist. Why? Before the bullets where in final form we we're guessing at what the length was going to be and I was back and forth between 1-7 and 1-6.75 twist. So settled on 1-6.75. The barrel was done and being fitted before the 150's came out.
