Hi Two !0's

not sure if this is going to be of any help, but i load the LAPUA scennar 250gr match bullets at a speed of around 2880f/s on south african powder S385 which is the same as your MRP or AR2213, i get really great groupings of around 13mm for 10 shots at 100 yards i havent yet measured groupings out at 1000 plus yards but i do hit an 8" gong every shot at 1000yards, i have shot Springbok and blue wildebeast ot at 880 yards and had really good results (all kills were 1 shot kills with the animals falling where they stand

I shoot 300 SMKs almost exclusively now. Simple and easy.

Re: 338 lapua help

hey there, what gun, what barrel twist are you running?

i'm running a 1 in 9 twist barrel (savage BA110)

here are some of the loads i've had good luck with

most consistent load (shot a 6" 5 shot group @ 980 yrds)
225gr accubonds over 87.0gr IMR7828ssc OAL 3.670" 2900fps, supersonic to about 1300yrds according to my ballistic data.... expansion questionable as on the only live animal i shot it went through and through on a broadside lung shot, small entrance, small exit but it did turn the lungs and heart to mush at 560 yards ...

second most consistent load (holds right around MOA but i am still tinkering with OAL's)
300gr lapua scenar OAL 3.664" or 300gr Sierra mk OAL 3.714" over 89.2gr Retumbo @ 2780fps super sonic to about 1900yrds...
both bullets seem to act identical in my gun and i have been using them interchangeably with no change to point of impact to 1000 yards. i have no experience on bullet expansion on live game for either but from what i have read from others shooting 338 edges and lapuas the 300gr sierra has been working well as far as terminal ballistics is concerned.

The more i think about it though, anything getting hit with 2000ftlbs of energy in the vitals is gonna be dead so i would worry more about accuracy and shot placement first and consider really good bullet expansion a perk when selecting a bullet. And i think if you can get the 300grainers to shoot well i would go that route - better BC, Better energy at longer range.

However, the 300's might need a fast twist rate like 1 in 10 or faster so if you have a 1 in 11 they may not stabalize well.... Then i would be looking hard at using 250's like trg42338lap suggested.... (i have 100 lapua 250's sitting on my bench but i havent got around to trying them out yet)

Oh yah.... Lapua brass and CCI LR magnum primers

Re: 338 lapua help

92-94 gr Retumbo 300 SMK's = Dead Animals at any reasonable distance

H1000 works well also just make sure what ever you buy is in 8lbs Jugs

Almost the exact load I shoot. I get a little riskier, but I haven't seen any overpressure signs yet.
