Thread: Reday to find a load...advice please

Ladder really means nothing at 100yds
You'd see a lot more at 200

yep

all good when you have access to 200m range

Will travel 40 mins to Bruce range in milton which is 300, maybe even 600, that will test the 4.5 power scope

Cheers

What charge did you go with for the group?
46 46.5 and47 looked promising on your ladder

I went with 46. Loaded at 2.800 so by my reckoning 30thou off lands, did not want to seat to close to I get a second opinion on distance to lands.

Lot of guys use it as a go to load, not giving up on the 46, could have walked up the page with barrel heat, I normally shoot 3 shot groups with no problems.

The ladder test was shot 1, walk down mark target, walk back, did not want heat to affect it.

I will load some at 46 and fiddle with seating the pill closer to lands,

I thought I would also try 46.5 and see if the extra 1/2 grain tightens it up

I run 2208 for pretty much everything cos I have lots of it and can still get 3200 with 130 barnes out of 22'' no visible mussel flash but can see it on film. Obviously a faster powder would better suit this weight but it still goes well.

In my suppressed 18 incher I got a max velocity with 2208 and 150gn SSTs of 2800fps with a heavily compressed 49gns. Groups around .8 of an inch at 100. With 2206H and the same pill I'm getting the same velocity with 2 grains less powder and accuracy of around .3 MOA at 100. Found 2206H better than H335 in my rifle with the 130gn TTSX also. Same velocities with less pressure signs and similar enough accuracy.

Interesting.

Not .308, but when I was messing around with the 68gr Hornady BTHP in my M4, 2208 was yielding pretty poo velocity, around 2450fps with 24.5gr, not a max charge but I don't think adding more powder would have helped much. I switched to 2206H and the start load was doing around 2650fps, worked up to the max 26gr C, and got 2864fps avg, with usable accuracy. This is out of a 16" tube, I'm sold on it for short barrel work - only wish it was powder measure friendly. Will try BM2 when I run out for that reason. I'm pretty sure you would see similar results in a short barrel .308.

Ok Bit of an update

Day off work today so caught the sailing..wahoo, big arse bacon sandwiches, walk the hound...good day head to the range.

Last time out the 46.5 gr group was shit so thought I would push them a little faster and see if they tightened up, turns out was a good guess






So feeling pretty good with that I had also rolled up some Barnes 130s to ladder test, this time 3 shot groups to see if they were printing ok on the way

Mmmm...pretty happy with that, next load

This load starting to get hot..slight ejector marks and very slight bolt stickiness

Nice thing is this printed at the same height as the 49.5gr load so will load 3 at 49 see how they go for height and load up a few at 49.5 to check the wee group not a fluke.

So seem to be making some progress.

Thanks to all the guys who have chimed in with assistance and answering questions.

Cheers

I must get a bottle to test, art, too many options to play with

Getting around 2650fps out of my 18incher with 150 speer btsp, and 45.8gr of 2208

Not just F class....seems popular for 308FTR. Of course then there is 2209 as well....so many options....

Not seen you at Trentham? Shot 2 x no4 Enfields last weekend, great fun even if I sucked.....playing risk with my elbow, but it seems to have healed OK....

Running low loads, 37gr 2208 behind barnual 180gr fmjs. Next time 308 150gr fmjs and 39gr in one and 174gr matchkings with 37.5 gr in the other.

Thinking about PH TX1200 at the moment....fairly cheap....
