Where to start? Found the answer!

I wasn't able to load more. I've got a pretty good load for the Sierra 250 GameKings that I'm going to use.

You last group is very nice. I'll have to buy some of those bullets and try again and load up to 86.0 of H4831SC.

Give me a few weeks and I'll post my targets.

80Maro,

Hogdon just added the 265 to their 338 Lapua loads. It wasn't there this morning - Cartridge Loads - Hodgdon Reloading Data Center - data.hodgdon.com

Understood. As I was shooting the groups I was dead determined I was not going to buy these again, then lo and behold I shot the last group. So now I need to buy another box to confirm the results and get some actual muzzle velocity data. I just picked up a 50 box of Sierra GMK's so i'm going to try and find a load for those. I'll try the data you posted on them.

Good luck with your hunt! I head out for a week on the 15th for Moose. Hopefully i'll find something by then.

Sweet thanks! WOW 74.6-79.4 of H4831 and i'm runnig 86.0 I wonder if anyone reading this with quick load can do up some numbers real quick.

My 250 gran Sierra GameKing load is 97.0 grns of Retumbo loaded out to 3.618" (.030 off the lands). My M700 has a 26", 1 in 10" barrel. Give it a whirl.

I don't think you are understanding the "JUMP" concept with Barnes bullets. .010" jump is not enough. Barnes recommends .040-.080" jump. I don't have a single TTSX bullets that is closer than .100" and they are all sub moa and mostly sub .50."

You were absolutly 100% right!

I'm really glad to see that the bullets are that accurate. Barnes is local for me (Utah) and I'd like to support them as much as possible.

Below is today's attempt at the 265LRX again. Load was 80.0grns of H4831SC using CCI LRM primers (minor primer cratering). I varied the OAL. My OAL touching the lands is 3.783". Also note that the top row was done using 300grn SMKs.
