Fellas i really dont know were i am going with this except i am wanting to find some 6ppc bullets on the .750 jacket with a blunt ogive say around 6 or 7. I am wanting to do some experimenting with these short fat bullets while it is still cold here in Illinois and compare my results this summer. I will also use some bib 68gr BT or ultras in this test. I am wanting to see if these short fat bullets shoot better in this cold weather compared to a longer more sleek bullet. I have a new krieger 14 twist for Dave bruno that i have high hopes for. LOL!! I havent gotten to shoot it much as i am waiting on new brass. Anyway I forgot to mention i am wanting these short bullets with a Flat base. I have some Ulrich 66gr bullets in a BT and i just absolutely love them. I dont know if the new barrel will or not but i also have high hopes.
It seems to me that i read somewhere that a short fat 6mm bullet will on average shoot better in a 14 twist than some of the newer longer 6mm bullets in the 6ppc with a 14 twist. I dont know if this is true but i am sure i read that. I guess i dont question that to much because i know how Georges little bullet shot in a couple of my older barrels, but i do wonder how these short fat bullets will shoot at 200 yards? Will the longer more sleek design out shoot the short fat bullets at the longer yardages? Basically I'm just thinking out loud here but i thought this might spark an interesting read. thanks fellas its really cold here and no end in sight and i am going crazy. I really feel bad for you northern guys. Next winter my shooting range will be done so it wont be quite as bad but this winter seem like it will never end. We have a shoot in February in St Louis so this is another reason i am wanting to do a little testing with some short fat 6mm bullets. It will be cold down there for sure. I did order some cheek 66gr 6mm bullets on a .750 jacket but i dont know when they will come. it may be a while? Thanks lee

Bart Sauter offered some sage advice several years ago. Find one bullet, powder and barrel that you like and learn how to make it work. I think also that your reamer should be a good match for the bullet you intend to shoot. I shoot Barts 68 HeadHunter bullets and I copied his reamer except I changed the neck size to .270. This turned-out to be a wise decision.

You can get caught-up chasing your tail trying to find the Holy Grail. It is more important to learn how to tune and read those pesky windflags than all this other stuff. Practice every chance you get. I have learned more shooting in matches than I have learned practicing.

I really need to take my own advice. I have all kinds of bullets, powders and barrels! Bart hit the nail on the head.

Good Luck.

Nothing is better in life that scoring a great Lot of bullets, and having a couple of good years. I did that for darn near three years. I had 10,000 great bullets that helped me win a lot.

As good as that is, nothing is worse than running out of those, and having to seemingly start all over.

I have about 7000 Barts .790 BT's that are pretty good. Come heck or high water, that is what I am going with next year.

By the way. Follow Gary's advice...........jackie

A few of us have been having this discussion up here in Canada. If we compare average temperatures, with a lot of the ranges in the US where the big matches are held, our temps are cooler. I am with Lee on what he is wondering. So far I appear to have better luck with bullets on a 790 jacket versus an .825 in 13.5 twist barrels.

The closest I have to seeing it was with my 10 twist 6BR and 95gr Sierra matchkings. We know that twist can be marginal for those bullets. At 20 deg celcius and using H4895 I had no problem with them stabilizing. They shot not bad out of the rifle. When the temp dropped to -25 deg celcius they would not stabilize but keyhole at 100. First thought was lower velocity because of the cold. Pulled out the Chronograph and the velocity was the same in that 45 deg temp swing. I then realized it was not the temp it was the density of the air.
This is similar. I wish I had the time and resources to try and study this more but I am going to stick with the theory that a shorter bullet just may work better in what Lee is thinking.

This is my limited thoughts.
