Derek DrinkwaterNathan,Have you spoken to George at rocky mountain bullets lately? Any chance on getting a bunch of the new 325gn 338 projectiles to try, the BC's seem outrageously good! Would like to know if they kill as well as the 225 and 250's you have studied, Your thoughts please Thanks Derek |

Nathan FosterRe: 338 LapuaHi Dirk, I haven't tested the 325 RM, I really need a 9 twist rifle to test this bullet. However, based on what I have seen with the 225 and 250gr, I believe the 325gr would have too much momentum on the lighter game you generally hunt, producing limited fragmentation at long ranges, resulting in clean but delayed kills.This is where we have to be careful with caliber choice as much as bullet choice. For predominantly light framed game with occasional animals weighing up to 150kg (330lb), you will be hard pushed to beat your current .300 Winchester Magnum set up. Especially considering that yours gives a whopping 2950fps with this bullet from its 26" barrel. |

Nathan FosterRe: 338 LapuaA couple more things to bare in mind, you would have to open up the bolt face for the Lapua and there is no going back once this is done. As for the question of the mag box length. Your M700 has a mag box 94mm long. From this, 1mm must be removed to allow for smooth feeding, leaving a max COAL for the mag box of 93mm. Now, if you go to the Rocky Mountain article in the KB, you will see the optimum mag lengths for the Lapua and .338 Edge somewhere around the second to last paragraph. |

Derek DrinkwaterRe: 338 LapuaHi Nath,Nar I wouldn't touch the sacred sendero! I have been looking at a new AR-30 in 338 lapua just for fun! They are 1-10 twist though. You say a "clean but delayed kill" that suits me as I don't want to waste any meat! You know me always eating and not wasting a scearric of meat! Would be keen on getting a water buff in oz one day and don't intend on gettin too close to em! I will work on the 208 Amax in the 300 for now and see what sort of results I come up with. As you say I'm getting 2950 fps but only had about a 3/4inch group at 100yrds so will work on getting a few tighter groups even if it means slowing them up a bit. Cheers Derek |

Derek DrinkwaterRe: 338 LapuaNath,re the 178gn amax, maybe i should stay with them after bowling over 2 pigs tonight! ask Longshot how many he shot! not many when he brings a remmington bolt for a tikka rifle! ha ha ha ha ha ha I emailed armalite 2 nights ago and they wont do a 1off 1-9 twist in the 338 so may have to look at other options if we want to try the 325gn cheers Derek |

Nathan FosterRe: 338 LapuaOk, slow killing/ low meat damage is problematic when shooting on terraced bush country or alpine terrain. It is important to be able to anchor your animal on the spot or near to it, to save losing the animal altogether down a bluff system. Something to always keep in mind.I am not really a fan of the .338's for use on truly heavy game. The .375 is more my minimum if chest shooting large Bovines. The Australian Water Buffalo is larger than the Cape Buffalo and can be slow to take down. One of my favorite combo's for fast killing large animals is to use the .375 RUM loaded with a 300 grain bullet to 2950-3000fps and to get in close, inside 150 yards. The .375's aren't the fastest killers on the largest of game but- using extra velocity and getting in close changes everything. A 300 grain .375 grain bullet at an impact velocity of 2600fps or above is very fast killing. I prefer either a Woodleigh or Swift bullet. When hunting the top end, one thing you have to watch for is dodgy guides handing you a Brno/CZ in .375 that has never been properly sighted in or accurized. Loaded with whatever factory ammo comes to hand, the guide gets the client to fire a few of shots over the bonnet of a land cruiser at 50 yards, rifle groups about 4" and the guide says that good enough, then off you go. The result of the hunt is a buff with multiple shots in it, trailed over a km or so, just a total stuff up. In Africa, its often the other way around with the client bringing the dodgy rifle giving the PH the run around. When planning any trip of this nature, even if its just a pipe dream, do the home work, do the hard yards, set your rifle up properly and get it shooting straight. Use as much power as you can manage. My .375 RUM is bedded into a stainless chassis, it shoots a half minute or less when I am on the ball but it really needs a muzzle brake, though the lack of a brake has taught me a great deal about the effects of various shooting techniques. It has also taught me a lot about scope limitations. You are most welcome to borrow the RUM if you want to plan a trip to the top end. If so, I will fit a brake. Its there to be used, not looked at. |
