338 lapua any good loads?

[nathanielw]

I just picked a Sako trg in the 338 lapua its a 27" barrel with a 1in10" twist i got some sierra 250gr matchking's and some 300gr matchking's i was just wondering if anyone could give me some good ideas on what to load with and how many grains.

I have used this one that I pulled off of Relaoder's Nest a while back with OK accuracy.
86 gr. H-1000 under Sierra 300 HPBT Lapua cases and CCI Mag. Large rifle primers.

Out of an AR-30 I flirt with 1" @ 100 .
I just need to play with seating depth a bit before I say I like it- also, need to wring it out well past 100 yards but that is more difficult given the 2 hour drive to a range with that distance.
I have also tried Retumbo and 869 but did not get what I was looking for, at least with the 300 gr. Sierra.

For the TRG....Work up to max of 91 H4831SC in Lapua Brass Fed 215 Primers with a 250 Scenar.

I shoot a AR-30 in 338LM. My load if a full charge of CCI LR Mag primer, .338LM Lapua case, full charge of H1000, and a 300gr. SMK. These are loaded to fit at the longest length and AR30 can fit in the mag and still not touch the lands. In my rifle it is far less than a 1MOA load.

If you are going to shoot long range with your rifle it is best to shoot the 300gr bullets. The BC on the 250’s is not that great, but only your rifle will know what it likes to shoot.

I also have a TRG-42 but with the 1-12 twist so i shoot the 250 scenar exclusively. My load is 89 grains of H4831sc w/ fed 215 match primer and seating depth measured with a sinclair comparator attached to the calipers of 3.992. Just into the lands. Velocity is 3000fps and very low standard deviation of 3 to 6 fps. My headspace is bumped .001 from tight bolt lift every time i load. Necks skimmed and .002 neck tension This load shoots 1/2 MOA for me everytime.
