Failsafe would probably retain much better long range velocity if the hollow tip was filled with instant glue.

Not sure why you would want to fill a bullet's hollow point with glue, since I don't think it would help the ballistics any. I don't think the hollow point creates as much drag as you think it might, but then again I'm not a bullet expert only a bullet wannabe!

Hollow cavity acts like parachute for wind.

Filling the hollow is not going to be enough. That hollow point is no different to a flat point with the same meplat area. One would have to 'shape' the filler into a rounded or sharp point. That might be difficult from a consistancy point but probably do-able. Why not try it and see what happens? It might turn out to be quite quick and easy!

I shoot a "lightweight" (featherweight) model 70 pushfeed in .270 WCF.

While it's never been terribly accurate in shooting 3 shot groups (3/4 to 1 1/4 moa)--the barrel warms up and throws the 3rd shot--I can place the first two inside a dime everytime. Oftentimes, I can get the first two shots touching.

If I know where the first & second shot are going to hit, I have only myself to blame if they don't!!

As to effect on game--I just got back from a moose trip in Ontario; there I shot a nice 1 1/2 year old bull at a little more than 240 yards.

I was pushing a 150 gr. A-frame at about 3000 fps. The bullet broke the on-side shoulder, the spine, and the off-side shoulder. The animal droped at the shot.

The bullet held together nicely, and mushroomed as advertised. I found it under the hide.

I'll post pics when I get them off the camera.

Bottom line--I can't complain about the .270 shooting modern projectiles!

Nice one!
Have you considered firing a 10 shot group over a course of several hours? Well OK, seven then - they say that is the minimum to give a true indication of how the rifle shoots. In the name of science! It's just that I would be very interested to hear how a rifle that prints the first two shots together would fair with several consecutive two-shot groups over enough time for the barrel to 'normalize'.

(Two broken shoulders and spine - wow!)

I don't think of my Mark V weatherby in 270 winchester as all that accurate, nor near the equal of many other match guns that I see targets posted for. I see amaizing groups posted on the errornet and know I am a poor shooter based on these postings. This blue steel inexpensive Weatherby shoots OK sometimes a half inch at 100 or so with several different 130's and the 140 NP. I have burned a couple of pounds of RL22 and H4831 in the gun. It has one of those cheap Zeiss Conquest rapid Z's on it, the one where you cannot see the reticle after dark, mine was working 30 min after sunset yesterday but then it got dark. Lately I have been shooting 57 grains of H4831SC under a 130 grain Nosler second's flatbase bullet, this shoots pretty good and does not seem to kick as much as a 30-06 with a 150 I had in an identical weatherby that I sold. My .270 Winchester seems to be "just right" for what I do, except of course it is not as accurate as many other cartridges and rifles, the funny thing is that I like the rifle and cartridge despite the fact that it is not a tack driver. I guess it just puts meat in the freezer everytime it gets a chance.

Half inch is the best you can do? I wouldn't feel too bad about it, that is good enough for head shooting sparrows at 100 yards.

It might act like a parachute for the wind but there are a lot of HP Match Grade bullets out there. Regardless of caliber and HP design those bullets still have very high BC which I don't think you will improve by filling the tip with glue, in fact you will probably make the bullet's BC worse. Everything I've read on match bullets is that the hollow point is used to shift the center of gravity on the bullet to the rear and giving it better in flight characteristics. Filling the tip of those bullets with glue will only change the characteristics of a well designed bullet and probably for the worse IMO.

Mmmm... I thought the hollow point was a function of construction method, which allows for an accurate base formation. Also, by leaving the tip 'hollow' better control can be had with bullet weight, since none of the core gets swaged out to form the tip. But then, I was just speculating.

Very astute or something like that! roger

Good morning 303,

I've sometimes thought of shooting a buch of groups over a period of time long enough to keep the barrell cool. I might just do that at some point.

The problem is finding time!

I'll let you know when I do (but it maybe after Easter, 2009!).

I have owned the same 270 win for 22 years. I have yet to take a second shot at anything I have shot, & I haven't had to track anything ever. I have killed deer, bear , moose, coyotes at all kinds of ranges.I do not know how tight the groups are on this rifle I just sight in every fall and go hunting tight enough groups for me, it kills quik and as humanely as possible. I own other rifles but if I had to put my life on the line I would automatically reach for my 270.(North American game not african DG)
Just my 2 cents

Just curious, but do you shoot the same bullet at everything? Have you been shooting the same make bullets for 22 years?

Found myself wandering around a gunshop (again), late 1990's, spots an old Sako Finnbear on the shelf, gets it handed down off the chain, This old girl is well bashed about, I'ts got a four inch long scar in the steel at the business end, a strange looking ejector blade, (busted off), & it says on the action .270win!, well I'm a sucker for a sad story, I had a slot on my F.a.c. for this cal, so we went home, had her repaired within days by a reputable smith in Wilmslow, shot some crap groups at the range & decided to give her the wipeout stuff, since then she's been recrowned & bedded,& with 130 grain Hornady SP's over 53 grains V N160 puts Scots reds in the freezer no problems!

"Either the .270 is one of the most inherently accurate rounds you can buy a rifle chambered for, or I'm just very lucky with the three I have bought over the years."

Probably just lucky. 90% of my rifles will shoot sub MOA with factory or handloaded ammo. Every now and then I get a rifle that's a little more finicky. Seldom do I get one that needs a bunch of work to get it to shoot sub MOA. But that's one of the benefits of shooting a Sako.

Actually, I don't care much for the 270, but all those that I have owned/shot have shot very well right out of the box. Cartridges notwithstanding, the worst luck I have with a particular brand has been a few of the hand full of Ruger M77s I have owned.

Doc, as long as I remember I have shot core-lok 150 gr at everything I have killed. Played around with federal's for awhile but always core-loks. My 270 is the only rifle I haven't reloaded, found it very accurate and worked great no need to tinker with that one, as I said my go to rifle
