I've got a pack of the same I'm about to load, with 2209 though,
I've also got stacks of Nosler and Hdy 168gr BTHP, that honestly, aren't marketed as hunting projectiles, but at over 3000fps the recipient wouldnt complain....(No, those are target round, they wont expaaaaand, aaaaaaah :roll: )

Also use Sierra GK in the larger cals, I know theyre available in 30cal in lots of masses from 150 to 200gr :thumbsup:

G'Day

I use Woodleigh 220gn RN with AR-2213-SC and WLRM Primers. I don't work up the load to the maximum either.

As can be deduced from the following pic, the projectiles perform very well. I have taken Sambar, Fallow, Red Deer, Buffalo, Camels, Pigs etc.. with the 220gn W65C. The projectile in the pic was retrieved from the opposing shoulder of a Sambar stag, he went down like he was hit by a bolt of lightning.

The projectile in the pic was retrieved from the opposing shoulder of a Sambar stag.JPG

The Protected Point 200gn are an excellent choice also.. I consider both the 200gn PP and 220gn RN, to be excellent choices for the .300 with regards to Sambar or any other big game on the planet for that matter.. Woodleigh make nice projectiles IMHO..

The 200gn PP's have a rec. impact velocity of 1900-2900fps and a SD of .301 / BC .450

The 220gn have a rec. Impact velocity of 1900-2400fps and a SD of .331 / BC .367

The 220gn is just something else to consider.

Edit.. Due to/ replacing pic after Photobucketofcrap, revoked free 3rd party hosting.. :roll:

Gentlemen
New to all this online forum stuff so replying as if to a 5 year old child is recommended !! Not new to reloading but am to a 300 Win Mag I recently bought second hand, it is Rem 700 with a SWFG heavy barrel, fitted with terminator T2 muzzle break. It dropped some camels recently at 100 - 250 metres using factory Hornady 200 ELDX, however closing the bolt on some of them was near impossible forcing me to sort through the ones that did close nicely, believe me there was a huge difference !! Therefore from reloading experience with my 204 and 308 I seek any and all advice/ recommendations you may have had with 300 win mag, eg. zero distance, projectile weight, primers, powder etc etc. I'm not trying to get on the Olympic team I just want to drop everything cleanly I shoot at.
P.S. The greatest sporting event on the planet is the Isle of Man TT....

Hi all
I load my 300wm with ADI 2213sc, Federal 150 magnum primers and 180gr Hornady interlock. I get about 1inch group at 100meters
This is a accurate load for my rifle.
I have tried other projectile and found they exploded at close ranges whilst hunting. Too much meat damage for me. So I am now trying these.

I found when reloading the fired cases, I had to trim some of the cases, as they lengthened and would not chamber if not trimmed.

I zero my rifle at 200meters and its about and inch high at 100 meters.
With a quality muzzle break, the 300wm becomes more pleasant to shoot. :thumbsup:

150gn is plenty for sambar, smash in some 2209 or 2213sc or equivalents and you will be cooking with gas, lower recoil and higher velocity with flatter trajectory than using 200gn pills or even 180gn pills, if a 270 with 130gn moving at 3150 can knock a sambar arse up, then a 150gn out of a 300win going 3300+ is going to make a light picnic of the event.

oh didnt see your post properly there NK,

My advice, if you aren't already, start reloading, I use 180gn on camels, they do fine but using soft points they cause a fair bit of devastation going in, so I tend to either aim for something that will bring it down immediately like a high lung/aorta shot if possible. or a lower double lung with some other essential parts affected, and always be prepared for a fast follow up if needed. Obviosuly if the thing is just standing there, the 300 removes its head without much left to explain. 30 cals dont always put camels down in one go regardless, heck even some 40+ cals dont despite pushing 300gn+ at decent speeds over 2400fps. but when they are calm and not adrenalized they tend to be pretty soft targets.

as for your tight bolt, I would be checking all your brass is in saami spec and I would be measuring the lands/freebore to ensure that the projectile is seated to satisfy this, that is if you want to get technical, however if you can verify that all your ammunition sits well within saami spec, perhaps have the headspacing checked, even a fraction of a thou out can cause a tight fit and you dont want to damage anything, especially out in the field, luckily for you people are more than versed at working with remington actions, so you wont have any dramas sorting it should that be the issue.

cheers.

Appreciate your info gents , much to think about, I’m likely going to go with 200 grain as I tried some Sako 180 and Hornady 200 to initially sight it in and the 200’s were a lot tighter grouping

Not sure why some of your cases would not chamber, was the brass fired in the rifle previously? Are the bullets seated too long in some cases? I wouldn't think that if one case chambers without a problem, another which is only a fraction of a thou bigger is going to give you any issues. You should be able to measure the difference between the two cases and identify the issue. If you have a small base body die, you can push the brass around and make it chamber, unless it was fired in a very sloppy chamber previously.

I use a 220 grain Hornady ELDX and RL22 powder, pretty empathic on game and great long range accuracy. All of my Sambar hunting has been at short range, usually 50 metres, and the high BC bullets are a bit wasted in that application.

ADI list another 200 grain projectile starting at 74 grains of 2217 which will get you started. You will find that 2217 is a pretty good choice for your application.
