I don't have a chrono but I am concidering purcahsing a chrony F-1 so that I can calculate ballistics. Should I take the plung? How are you suppose to use it to aid in reloading? |

Thanks for the help, but what about small bullet higher velocity vs. large bullet slower velocity; both have the same energy? If they have the same energy, by conservation of energy, they should have the same impact on the animal. Any thoughts? |

When they say "work up a load" does that mean that you can go higher than the powerd manufacture's max load? How much margin for error is there if you do go higher? |

Seeing how I just got back from the range I feel I need to add my 2cents. I have found most bullets I've tried are very accurate.....<1 inch at 100yds. MY daughter dropped her first deer year and a half ago with a Sierra bullet. Small buck angling away at 160yds. Bullet went in just behind last rib, thru boiler room but didn't exit. It was there 100gr. Lost over half its weight. Been playing with varmit and deer loads. I don't have a crono but the range I go to has 100, 200, and 300 yds. I use the bullet drop over the ranges and Dallans program to approximate the velocity. I think it works pretty good. I just shot 4- 3 shot groups all less than .75 in with Hornady 58gr. and Speer 90gr. I have been using 414 in the past but have switched to H-4598 for temp. stability. I have gone back to H-4350 for the 90 gr. bullets. I love the cartridge. It gives be the accuracy and confidence I need in the field. Generally I get the best accuracy just at max load or just below max. Good luck, it's a great caliber. I can shoot bullets from 4000 f/s on down. |

I am new to reloading and I have many questions. My background and things to keep in mind for these questions: I purchased a .243 to do everything from varmint hunting to deer. I live in the west were there is lots of open ground for all types of hunting. I am a fan of high velocities and flat trajectories and got into reloading so that I could save an arm and a leg and to produce ammo that is better than the factory. 1) I reloaded a batch of Nosler 55gr BT with 45.1gr of Varget and I am getting a very large, and noticable through scope, muzzel flash. Is this normal for Varget? I am thinking about switching to H4895 for this bullet to get rid of this flash. I have a 24" barrel. 2 part a) My main question is on the topic of deer hunting. Since I will have chances of taking deer all the way to the .243's max range, I want to use a bullet with a high BC. The Speer Spitzer BTSP 100gr and Sierra's 100gr SBT gameking. These bullets have a .430 BC. As for powder, I am undecided between H414, H4350, IMR 4350. I am leaning towards H414 because it has higher velocites over a larger range of bullets. What powder should I use for this hunting load? Hold onto your anwer until you've read part b. 2 part b) In my research for the best deer load, I discovered that Speer's 85gr Spitzer BTSP (BC of .404) backed by 45gr of H414 @3306 fps has the same energy as Speer's 100gr of the same bullet backed by 40gr of H414 @2963 fps. Since the 85gr has a flatter trajectory, should I use this bullet for deer rather than the 100gr? Your advice would be greatly appreciated. Thanks P.S. What sort of primers would be best for this deer load? |
