With 250g barnes MZ, my disc rifle shoots 1'' groups. 300g barnes, sst, knight jacketed soft points and 310 lead hollow points tend to all shoot into 3'' or so. When I shoot these same bullets with 100 grains (pyrodex pellets), they all shoot a little better. My sense is its just like working up handloads for a rifle--you need to find the right combo. I've used the 250g barnes on mule deer and antelope out to 219 yards. I've never recovered a bullet and performance has been deadly--they simply drop. For elk, I use the 300 grain barnes of jsp and put up with a little less accuracy.

bc,
I really like those "Dead Center" bullets from Precision Rifle Bullet and their web site is loaded with great technical information. You can order from them directly, but only in bulk. I think 50 bullets is the minimum order. You should really stop by their site and read all the stuff about all their testing they have done with different bullets on different game animals. It is really good info

mlaub, you wouldn't sell me 10 or 12 would ya. I would hate to buy a whole bulk of em and not shoot for me.

By the way, this is formerly bigcountry. Login screwed up. I work here near BWI.

Well, I took my new Disc Elite out this weekend. Got amazing accuracy at 100 yards with my old tried and trued load of 95gr of Pyrodex and 240gr XTP's. Around 1.5" groups twice. But tried a few combos with the 250gr SST's, and they didn't work out.

Tried both 120gr, and 150gr of Pyrdex loose powder, and got 4" groups with SST's. Lots of combos left to try with high velocity loads.

Personally, I find that more times than not people get too "into the numbers" and begin to to forget the fact that no matter how much energy any projectile may have when it makes contact with an animal, placement of the projectile as close to the vital areas as possible, will have more impact on how quickly the animal is put down than how much energy the projectile possesses. Energy transfer will also be relative to projectile composition when we start looking at potential energies. You could have a projectile with 1 million ft/lbs of potential energy, but, if the projectile is incapable of releasing it, you have less trauma resulting than if it could. Example..the millitary's use of steel core 5.56 nato ss109 62gr. steel-core penetrators, as opposed to a 62gr, lead core, soft or hollow points. One is designed to NOT expand (release it energy) and the other is...that is why they are outlawed for combat because they will do more damage even though they both have very similar if not the same potential energy. Accuracy is more important to me than how much power my setup my have. But, I will also logically choose an appropriate round for my quarry. Which would be ANY legal round for use in my area. All calibers and setups have killed deer (in my case) including .22LR! Heck, many of the native peoples in the eastern Canadian Provinces regularly use the .30-30win to take moose...it all boils down to how profficient one is with their weapon.

Take into account that in most cases you may not see a complete powder burn when using 150gr charges. The length of your barrel will contribute more to the potential accuracy of 150gr loads. Most of the first 150gr capable inlines had barrels too short to accomodate (20-22"). Now more and more inlines are going towards the 26" and 28" barrels. A good test to see if you are getting a complete as possible burn is to shoot a round at white paper set about 10-15 yards from the muzzle and fire a round at it. If you see burn marks or even loose grains...that is a sign of wasted powder. I tried shooting 150 grains out of my old TC Black Diamond XR (26"bbl) and noticed 150 grains and a 300gr projectile didn't have much difference in velocity or downrange capability than a 300gr projectile and 100grains of powder. Of course every one is different, but, I would rather make better use of my money than shoot 150grains of powder. The powder I used was Hodgdon Triple 7 FFG. Having said that I am going to a TC Omega (with a 28" bble) to help increase my velocity and down range performance this year over that of the Black Diamond.

I DO NOT promote the use of the .22LR for deer or anything more than small game..just wanted to clarify that

WhackAbuck, that is how this thread started if you read back. I limit myself to 50 yards with 95gr of pyrdex. And want to increase it. See what I am saying. I mean lets say you have no problem bringing home 6-10 deer a year. And you love to shoot, and play around. Nothing wrong with playing with the numbers. Its gives you purpose and drive to go to the range number one. And more time you spend shooting, more fimiluar you are with your guns. All good stuff.
