And besides, I can’t find ANY large rifle primers, let alone most of these powders, on the Internet! Thanks again for any further ideas. I don’t have the time or money to try each one. While all will “work”, what I am after is which will like result in the best accuracy. So I stumped as to what is more important: faster burning or a more completely filled case. While the faster powders may be better based on the smaller bullet weight (110 gr at 2900 fps), the slower powders seem better at filling the case, resulting in more consistent burning. 308 case (3.43 cc) based on a percentage. Based on my Lee Modern Reloading, 2nd Ed, I identified the following for each powder I listed: A) relative burn ranking, B) volume of one grain of the powder (cc), and C) how much each load (I took average grains) would fill up the useful volume of a. Based on your input I did some more analysis on the subject. It seems there are quite a lot of varied opinions. Of course, it may boil down to whatever powder I can find! Any suggestions are appreciated. My question is which powders and powder weight do you recommend I try that have the best chance of being most accurate for a 110 grain bullet with a MV of around 2,900 fps, out to 100 yards? Here are the options I am considering: I figure the extra cost and slightly more recoil of heavier weight match bullets is not worth it, considering that I do not have a match rifle, and because I have read that the 110 grain Varminter can be extremely accurate when range is limited. My plan is to load 110 grain Sierra Varminter bullets and use a “starting load” that results in a MV of around 2,900 fps, while maintaining very good accuracy. 308 shooting for the foreseeable future will be informal paper punching at 100 yards, while sitting at a bench, I plan to reload lower recoiling, lower cost, lower wear and tear, yet accurate loads suitable for this purpose. – – VihtaVuori Oy Company, reloading booklet (1995) – – Numerous magazine articles on reloading special calibers and personal loads where noted.I have a Browning X-bolt.

If you are shooting for precision, you should weight each powder charge and put exactly the same amount in each case. The “boattail” is a very good long range target match bullet. There are a number of other high performance bullets on the market. 243 is really better for long-range, open country and not so much for the brush and woods. For hunting at long distances with an unobstructed view, you should choose the spire point with a soft lead tip. Of course, discard any cases that show a split anywhere on the case. Slow burning powders generally work better in longer barrels and heavier bullets.243 Cases will stretch, especially with hot loads, and you definitely need to check each in a case length guage and trim off excess brass. I have listed powders of IMR, Hodgdon, Alliant and Accurate.
