I have found that the .338 is superior in accuracy over the distance, utilizing the commerically available bullets. Although the .338 is shooting a 50 grain lighter bullet, it still carries an impressive 1,730 ft lbs at 1,500 yards.

Could not agree more. In fact the drop chart for my 338 Allen Magnum with 300 gr SMK and my 375 Allen Magnum with 350 gr SMK are pretty much interchangable out to a mile. Past that, with these two specific bullets, the 338 has a slight edge ballistically but it takes longer for it to catch up energy wise.

Bullet performance wise, have not been overly impressed with the expansion of the 350 gr SMK on game lighter then 400 lbs, certainly does the job but the old 300 gr SMK in 338 is hard to beat terminally on any game from deer to elk.

Bingo!

My personal experience with the 350 SMK on game is that it has never impressed me with the transfer of terminal energy. The .338 SMK on the other hand is about as good as it gets.

Re: 375-408

The 300 gr Accubond is a great bullet terminally but it gives up ALOT ballistically. The Rocky Mountain bullets expand almost violently, in my opinion they expand to much. I have not put a cutting edge bullet in game, they have several options in 375 cal but as mentioned, have never put one on game. Any solid copper alloy bullet makes me a bit nervous when it comes to consistant expansion at long range but just have no experience with them on game yet.

Re: 375-408

i'm guessing with good bullets, the 358-408 would be perfect!

Re: 375-408

The 35 cal has HUGE potential but unfortunately, its a dead stick with US bullet makers and do not see that changing. A good 325 to 350 gr VLD in 35 caliber would be a special bullet if designed properly but the demand will likely never be there except for maybe full custom bullets made in very small lots but small custom bullet makers.

Again, it would have huge potential however.

Re: 375-408

I don't have any first hand experience with the Rocky Mountain Bullets, but I do with the .338, 300 grain CE bullets, both on game and on paper at extended range. I am more than please with their performance on Elk sized game at ranges from 600 to around the 1,000 yard mark. Consistency in the accuracy department is what concerns me. Shooting groups on paper at 1,760 yards, in multiple calibers, has me a bit perplexed as they will not group consistently. Now, consistently is the key word. Good three shot, four shot groups are possible, but I have never been able to shoot a tight five shot group. Perhaps, these bullets are no better than the other solids that seem to share the inherint "solid consistency problem". Taking into account the fact that one has to run a sharper twist to shoot the solid, it does not leave much option if the combination does not like the bullet. One should never build a rifle around one bullet! Sooo, my bid is for the .338 combination..... that will allow the end user multiple comercially available match bullets to use in the 285-300 grain range.
Remember Germs... if we can't hit what we're aiming at, the rest is a moot point!
