My Howa .308 varmint is a 1-10 but if memory serves me the sporters are 1-12 I may be wrong.

Got my weekend sorted, next batch of loads to test, 47.5, 48, 48.5gr AR2208 COAL 2.635" picked up 20 of the factory loads to compare.

Pulled a bullet from a factory load, charge weighed just under 48gr, not sure what the powder is, grains were quite long.

I'd assume ADI would use their own powders in factory loads. Does it look like AR2208? Post a pic just curious.

looks different to my AR2208, grains were long and it was a cylindrical powder, shot all of it unfortunately so no pic.

this is my best group with my last batch of reloads, 48.5GR AR2208, 2.635 OAL, this group was alot better than anything else I shot that day, I held the foreend in front of the rest for this group and it tightened up nicely.

I'm pretty stoked to get this from a sporter barrel, I reckon I'll reload the next batch using the once fired OSA brass and load 48.5GR varying the seating depth from 2.635 out to 2.710ish moving up in 20 thou increments and looking for pressure signs.

best group I shot with the OSA 135gr factory load was 1.2-1.5 inch @ 100m but I didnt have good control over the fore end, I was trying to let it free recoil, which it didn't seem to like. I reckon i'll be either buying more of this factory ammo or in the least a batch of OSA brass as my once fired cases look like they'll make great reloads.

actually, no, 48gr would be way too high for 2206h

I think I remember reading somewhere though they did a blend(s) for their factory ammo, not an off the shelf option like we're offered?

Wish I could remember where I picked that up, can't remember :|

Na the 8208 is a finer granule than 2208

Finally got around to shooting this stuff in my Tikka this weekend and it was fantastic!! Clover leafing at 100 so I'm very happy...
Now to try and replicate it as a hand load...
Think I'll start with 2208 and work my way through a few diff loads...
Any suggestions on what the sweet spot seems to be in terms of grains of powder?

I posted my results in this thread already seems to be 48.5gr of 2208, OAL 2.635". Had 3 shots cloverleaf at 100m 5 shots fell under 1moa with my howa sporter. Projectiles are the Sierra 2124.

I'd suggest starting at 47.5gr and working up in your rifle.

48.5gr of 2208 is pretty full in a remington case, in the OSA cases I reckon the load would be compressed as they seem to have less volume than my current batch of remmington brass.

I loaded my once fired osa cases with 45.5gr, 46gr and 46.5gr of 2208 behind hornady 150gr SST, if I can get one of these loads to shoot this pill nicely I will buy a batch of 100 unprimed OSA cases as it's darn cheap brass @ $66/100

This ammo shots great out of my tikka t3x varmint, got it out to 400m no worries.
