Just food for thought.

Good luck....I am still waithing for my "FREE" bullets.....I won a pile of stuf at the last 1000 yard shoot.....among them , 300 Berger Bullets!!! I decided to get the new 300 grainers.

I appologize for the confusion in my statement. After re-reading my post it did kind of sound bad that way, I was aiming to use 92 grains but I did start out loading at 89, shot 5 of and went up 1 grain for each group till I hit 92. I saw the cratered primers at 92 and went back to 91 which like I said shot better anyways. I was in no means advocating people use a near max load right of the bat, should of been more clear on this and once again I apolgize for the confusion. But my OP was really more about the dicrepencies between what was posted on the Hodgson page and what I was seeing for other peoples posted MV's for this load combination

BMAN,

Exactly right......there will be dicrepencies as long as there are guns, loaders . and computers. Like I said. No two guns are alike. I had two different 30-378 WBY Accumarks..(I know, not a 338, but just to make a point)... I was loading for. TOTALY DIFFERENT GUNS. I think I even ended using different powders in them....same for the 338 Lapuas I have loaded for ....50/50 split...H1000 and RL 25. Probably could have been more, but those are the powders I had/tested. Anyond using Retumbo in them. I baught a bunch for one of 300 WBY's. Wild, wild stuff in that particular BBL!!!

300 gr Berger hybrid
89.2 gr retumbo
Oal 3.758"
2700 fps
(just started tinkering with this bullet... Reduced speed compared to smk likely because I had to load a lot further off the lands to fit the magazine)

285 gr hornady hpbt match
91.4 gr retumbo
Can't remember oal off hand
2822 fps
(showing very good potential

I shoot a McMillan TAC 338 Lapua and have developed three great shooting repeatable loads. A 300gr Berger over Retumbo at .015 off the lands shooting 2720fps isn't setting speed records but it is very accurate.

The 285gr TSX over Retumbo shooting 2840fps is a great shooter, my best 500 yard group was 1.6", the others are very close but have superior BC's for better long range shooting. I worked up the TSX load for an upcoming Elk hunt.

Another good shooter is the 250gr Lapua Scenar over RL-25 shooting 2905fps. all loads are three shots touching at 100 yards with plenty of speed to get the job done.

The TSX and Scenar are loaded at a length that will feed from the magazine. The Berger is fed one shot at a time. All loads are in Lapua brass and CCI-250's.

I'd like to know more about your rig. I'm interested in the carbon wrapped barrel, especially in the .338 LM. Please share.

Weight of rig (everything on it)?
Recoil?
Maker?
Performance (accuracy)?

email me at zeheev@yahoo.com if you don't mind.

Thanks.
