125 Speer TNT 308

[thatmikeguy]

Is anyone here having success with these?
I tried them with H322 and they didn't perform very well.
Which powder are you using?

Varget, 4064, both worked great for accuracy with 125's. H335 for volume hunting loads also works well.

 

[thatmikeguy]

That's good news. I'm fresh out of Varget but just bought some 4064.

Used them with both H4895 and IMR 4064. Both worked well but best performance (for me) was with H4895.

 

[thatmikeguy]

Thanks. I've been reading that 4895 is a great 308 powder.
125 grain is light on the spectrum for 308 so I wasn't sure what to try next. Powder is hard to get these days. I hope this changes.

I use Varget, and it's ok. The bullet is light, my load was for wolf/yotes. Ideally when these are gone I will not purchase again and keep with 147 or 150 grains.

 

[thatmikeguy]

I don't plan to buy anymore but I would like to use them up. I have 76 left. 45 grains of H322 produced a 1.6" group....at 50 yards. Not great.

First thing you need to do with these is weight sort them. They aren’t match grade and have quite a variance in weight. I finally got them to shoot OK in my Tikka with Dominion 8208BR.

 

[thatmikeguy]

I don't think it's that important to me to weight sort them.

First, what twist rate does your barrel have.

Those bullets are a bit short for a 1-10 twist and can be over stabilized at higher velocities.

I found the best twist rate for bullets that light, which I have shot thousands out of a Hunter Bench Rest rifle chambered for 308Win. with a 1-15 twist rate.

After that barrel was burned out, the next barrel had a 1-14 twist rate and liked the same load.

My present 308Win has a 1-12 twist rate and it also likes this load. Sub MOA groups out to 300yds, if I do my part.

I've tried it in a rifle with a 1-10 twist rate and it doesn't perform well. Two inch groups at 50yds and getting larger as range increases, to the point that at 200yds they won't even hit the target. My suspicion is that they are coming apart in flight, before they get there.

The powder I used was W748.

My accuracy load was:

50.0grn W748

Speer 125 grn TNT

CCI 250 mag primers

In using a cz557 with a 1:10 twist. I have been wondering if they'd shoot better if I slowed them down. So far I have only tried medium to max load.

I have found H335 to get GREAT fps and accuracy in a 308 Win with a 125 gr bullet ! RJ

 

[thatmikeguy]

The Speer SPBT 150 grain didn't perform well for me either. I will stick to Hornady Interlocks from now on.

So What is the rifle your shooting your loads from ? Brand - Model ? RJ

I starting to think I may need a scope. I was excited to get a rifle with iron sights but it's harder than remember. 50 yards wasn't too bad. I shot at 100 yards today. Let's just call it minute of deer ha ha

Ummm, how well do you shoot other rifles?

 

[thatmikeguy]

I have been shooting rifle and reloading for a long time already. With a scoped rifle and reloads I usually shoot moa or less. My best 100 yard group yesterday with iron sights was 2.7 inches. The next best groups were 4 and 5 inches. I suppose it's not bad considering the front post appears to be around 8 inches wide at 100 yards.

I wasn't being facetious with that question. Just eliminating a variable.

IMHO, your twist rate is to tight for that bullet. You might get away with the starting load.
