I need to find a lighter bullet for a .300 win mag remington sendero.The gun appears to have a long throat ,I'v heard all the senderos in .300 win mag do? any way I would like to find a bullet that will reach the lands but still be fully seated in the neck . I would like to find a 150 grain,no bigger than 165grain bullet and obviously would like it to be ballestically efficient as possible.has any one found one that fills the bill,nosler partition? maby a speer a frame?maby a barns x bullet flat base,a all copper bullet should be longer due to all copper construction altho i'v heard they copper barrels up pretty bad. I figure one of you fellers has run into this and probablyfound a bullet to do the job.if you found how did it shoot

wayles-
Try ballistict tip, or accubonds. You might find that your rifle doesn't like boat tail bullets and won't shoot well, but I doubt it as I've seen many senderos do well with boat tail bullets.

Hey wayles

Barnes Triple Shock 168 gr match IMR4831 powder around 75 gr for about 3350 fps. Start lower and work up.

Excellent accuracy and contrary to what you have heard they foul a bore less than most bullets. Do not get the regular X bullet cause those do foul a bore quickly, IME

Accubonds come in both 150 and 165 for the 30 cals, they are very long bullets.

I have a friend who shoots 165gr Nosler Bt's and a MAX load of IMR 7828, that shoots great.
Work up as always.

Measured the 150 gr. accubond and the nos. ballistic tip. They are shy of the lands by over .100 and still seat a full neck according to my stoney point device. They measure almost identical in length. It appears its going to have to be a flat base of some kind with lots of copper or a barns. seems like all the mfg. lean towards heavier is better in the choices available . My 30-06 loves the 150 gr accubonds and I am able to seat a full neck as well as reach the lands for best accuracy. I'm trying to avoid buying a bunch of bullets I have no use for and trying to avoid some recoil with the lighter bullets. Remington must think they need a long throat on this cal.

My heavy barrel 700P only likes the heavy pills, I tried the lighter stuff and groups were from average to terrible.

168 match bullets did the best of the light weights for me.

Sounds like you want a long bullet, You may want to look at the Barnes XXX they are pretty long.

Good luck

I have a 300 Winchester Sendero that likes the 150 Accubonds with 78gr of RL-22. Problem is seating the bullet outward and having more than a 3.45" OAL is too long for my magazine.

I know the problem my 30-06 has to be a two shooter.One up the spout and only one in the magazine.
Wayles

The fatter ogive on the 168 gr. TSX lets me get to the recommended .05 off the lands in my loooong throat M-700, while still having .308 seated in the case.

Well aside from stating the obvious that flat based bullets can invariably be seated to longer OAL's than boattails...

Frankly, I think unless you are shooting at a big animal
like a Moose that 165 partitions will get the job done, but will they shoot well in your rifle? there is only one way for you to find out.... try them.

I know very well how heated the discussion got on 140gr Vs 160gr bullets in a 7mmMag. and that's a 12% difference in weight, but anyone thinking that there is a big difference
in terminal performance between 165 partitions
and 180gr partitions will be working an uphill battle to prove it. 15gr of bullet weight makes a significant difference
in internal ballistics, particularly with regards to peak pressures, but in impact performance?
the more important question is what does your rifle shoot best.

NOTE:
God (whatever name you prefer) Save us from the Attitudes and Ego's that usually stampede in response to these subjects... (Just a little prayer, but I doubt he's listening)

it's only a 9% increase in weight... but the difference
in length of the heel may allow you to load them long enough (magazine length allowing) to get the mechanical relationship between the Ogive and the leade and get the positive effect on accuracy you seek.

What I do on most rifles is seat the bullet as long as the magazine will allow, smoke it (over a candle)and see if it touches the rifling.
I compare this (RCBS precision Mic) to a Loctited together sample cartridge that is assembled by final seating of the bullet with the action.

No, I don't have a 300magnum, but handloading is handloading.

Your really sticking your neck out now Allan. But I've got a 7MM actually a couple of them and I've got a .300 and you're right.

Hey AD

Not always true. The flat base or boat tail has nothing to do with OAL. The OAL is determined by the length from the point on the ogive where it reaches full diameter to the meplat of the bullet.

For example, I have a 30-06 where the OAL of a Nosler 165 gr Ballistic Tip (boat tail) is 3.370" and the OAL of a Nosler 165 Partition Spire Point (flat base) is 3.300". That same gun has a OAL of 3.3850" for the Accubond 200 gr (boat tail).

Now you might say "It's those damn long pointy plastic tips" and there be some truth to that.

Don't use those methods anymore. All of my rifles have sufficient room in the mag to seat out to the lands with room to spare. I use a Stoney Point Gauge, the Reeves tool and a Sinclair Comparator to find the lands. More accurate for me. Seating the bullet with the action can seat the bullet into the lands quite a way. I did that one time for comparison and the bullet was pushed into the lands .035". If I opened the neck for less tension then the bullet was grabbed by the lands and pulled out of the neck and had to be knocked out with a cleaning rod.

Back to the subject. IMO, a 180 gr TSX should be able to be seated closer to the lands than a 168 TSX. They decrease the ogive-to-tip distance in order to get more weight on the bullet.

Oh, BTW, proud member of the HBM, not the Attitude & Ego Gang

Wellll I went out tonite and tried the sendero out for the first time.Shooting a handfull of loads provided by the guy I bought the gun from. They were 76 gr. of Rl22 pushing a 168 SMK ,loaded over .100 from the lands.After 2 fouling shots The darn things shot .375 inch group! I could not believe it so I did it agin. Go figure!I have never been able to jump a bullet that far with any kind of accuracy . Needless to say I saved the last 3 so I could copy them exact.What the heck A blind sow finds an acorn occasionaly.The only reason I think the fellow sold the gun was it was coppered up pretty bad . It took 180 strocks with a bronze brush and barns copper cleaner to get it clean .Now if I can just find a 150 grainer that I can jump that far I'll be a happy man . Shoot I'm a happy man now!Thanks for all the input.

In my original statement I said nothing about Ogive shape, I was thinking about the comparison of bullets from the same manufacturer
one with a flat base one with a boat tail...

Say for example the two 120gr bullets Sierra makes (or used to)
for the .264 bore diameter? one flat base the other a boattail?

Basically I'm trying to tell you something... and that is that when you are trying to seat a bullet further out with a boat tail bullet you run out of bullet sooner.


Yes Ogive shape determines where you need to be, but you have more room to play with a flat based bullet.

Now, it that material to this specific situation? I don't know, I don't have
that rifle here to play with and trial fit...

Don't confuse them with logic Allan
