maximus Report post Posted February 14, 2015 I have a remington 700 in 243 win, i reload for 300 win mag and 308 win, just started reloading for the 243, my measurement for the coal with the gauge is 2.790 touching the lans if i take 30 thou will be 2.760 the book for the sierra calls for 2.650, do you think my coal is too long or should i go for the manual load?

jeffro Report post Posted February 14, 2015 If it feeds from the mag or the box then your fine. Also you may not even care if it feeds then just single feed them. Share this post Link to post Share on other sites

lancetkenyon Report post Posted February 15, 2015 Usually SA Rem 700 magazine box is around 2.900". Your COAL should still fit the mag and remain .030" off the lands if you measured correctly. Book show SAAMI lengths, what manufacturers use to fit in all types of stock firearms. If your guns likes longer than SAAMI, then go with it. Share this post Link to post Share on other sites

firstcoueswas80 Report post Posted February 15, 2015 What powder is everyone running for the 243? I was looking at running R22, R17 or H4350 with 85 and 87 grainers. I have plenty of it all on hand I think I will start with R17 as I only have one pound of that on hand and noting else to use it in! Share this post Link to post Share on other sites

HuntHarder Report post Posted February 15, 2015 I run Varget in my .243. Very consistant and pretty clean burning. Share this post Link to post Share on other sites
creed_az_88 Report post Posted February 15, 2015 R17 with 100 grainers for me. It seems like r17 has a very narrow gap for accuracy but once you find that gap, it's a really good powder for the .243. Max load produced very good groups for me. 1 grain under max was ok. 1.5 grains under max was horrible so don't give up on it If you're getting crappy groups as you ladder up. Imr 4350 seems to be the go to powder for many people in the .243 but r17 gave me better groups once I found its sweet spot. Share this post Link to post Share on other sites
