new 300 ultra

Well I just picked up a remington 700 sendero today in 300 ultra and need so advice on what to shoot from it... I want to shoot 230 bergers so I was wondering what would be the best brass? Anyone have any good loads with the 230s they'd like to share? They would be greatly appreciated!

Re: new 300 ultra

When I had my Sendero 300RUM I could not get bergers to shoot to save my soul. A friend has a Sendero 7RUM and has the same problem. I ended up going with 180gr hornady SST's. Just to hit the lands I would almost have to load them out to 4". I also install a wyatt extended box magazine and jewell trigger. I hated the stock trigger.

Re: new 300 ultra

I can't comment on the 230's but I do shoot the 215's. First they were very easy to get to shoot. All seating depths were shooting at 1" or under at 100yds. Ended up with a COAL of 3.843" 91gr of H1000, 215 Federal Match primers. Shoots around 5/8" at 200yds and is at 2990fps with a 6fps ES. Sendero with action work and other stuff. Factory barrel. 230's should be relatively easy to get to shoot. Send Berger a email they will send you some load info.

Re: new 300 ultra

I don't shoot a Sendero but I do shoot Remington 700 in 300 Ultra with the stock factory weight barrel and have a load using Bob Cautarucio 211 grn. bullet with 95 grains of Retumbo CCI mag. primer Rem brass and load that to maximum mag length which gives me 3150 fps. and shoots groups of .317"! I'm going to be using this load in Montana in two weeks on my Elk hunt. This is out of a 26" tube as well. Sighted at +3.3" high at 100 yrds. drop is -19.6" at 500 yrds with 3000 ft.lbs. knock down power plenty I would say.

Re: new 300 ultra

Alright guys another question, I was just scrolling through HSM ammunitions download that shows what cartridges they offer with bullets and velocities, it states that they're 300 win mag shoots 210 bergers at 3020 and they're 300 ultra shoots the same bullets at 2931 fps. What the hell am I missing here? Comparing the size to the both the ultra has much more powder compacity!
