whats your most accurate ammo 338lm

[BEAR1911]

just curious , mine is 285gr. hornady, lapua brass, H1000 at 80.8 grains around 2500 fps. my brother is telling me that seems slow .

all test loads are shot at 200yards for now . 5 shot groups all holes are touching each other , overall distance apart is 1.5" human error i guess.
hopefully i explained that correctly

I would post this question on snipershide as a lot of guys there are into this round heavily.

You could push it quite a bit faster than 2500 that's for sure. If accuracy is good and its doing what you want then no big deal. However you could improve trajectory quite a bit. Using the same bullet with rl25 I found an accuracy node around 2700. Rl33 gives the extra velocity over rl25 and shoots very well in my fcp.

+1 on looking over at Snipers Hide. Look in their RELOADING area. They have a section dedicated to 338 to 50 cal. In there you will find a ton of info on the 338LM. The generalities of what you will find are: Lapua Brass ONLY, FGMM 215M Primers, Retumbo is THE powder with H1000 a close second and a few using R25 or R33 with good results, for bullets it gets more variable; If there was a go-to bullet, it would probably be the Sierra 300 Match King, but the Hornady 285HPBT and AMAX are LOVED, Lapua Scenars have a very good reputation as well.

My personal load in my 110BA is Lapua brass with FGMM 215M, Retumbo, and Hornady 285HPBT sitting .010 off the lands with a COAL of 3.709". 93-94 grains of Retumbo yields 2830-2865fps and accuracy has been WELL under 1/2MOA with many groups at 100yds being in the .2-.3 range.

Hope that helps some

Retumbo is a dirty powder :(

[mudpig]

I've had NO such issue with Retumbo being dirty at the pressures it was designed to be used at. Light loads might be dirty....up the charge and things get pretty clean

[homefrontsniper]

I have read about it being dirty many many times. I have never used it?
I have two lbs & two lbs of R33
H1000 is the **** in my Surgeon Remedy . 1000 yards is a joke ;)
I'm shure it will do just as good and 50 fps faster maybe more?

thanks for the info , i spent a lot of time reading on snipers hide , looks like i will be trying 89gr the highest I've gone was 84.3gr
don't get me wrong at 200yds I'm cutting holes with 80.8 just curious about more FPS,

Make sure you fact check that load as internet loads can be disasterous. Just check in a reloading manual to make sure it is not over book recommendation.

THANKS AND YES I DID ,that's the max load from my hornady manual using H1000, 285gr HPBT the rain is really messing with my fun day of shooting
