Dac9976 Posted February 3, 2015 Report Share Posted February 3, 2015 Hi all Hopefully picking up my .243 this weekend, so new load development begins:) Anyone had any experience using Ramshot powder with the .243? I've got loads of hunter that I could use and there data seems to favour it. Cheers Danny. Link to comment Share on other sites More sharing options...
dannywayoflife Posted February 3, 2015 Report Share Posted February 3, 2015 Hi mate I am currently using magnum in my 243 under the 115 dtac. I don't know velocity as yet but I terms of group size it's very very good! Link to comment Share on other sites More sharing options...
Dac9976 Posted February 3, 2015 Author Report Share Posted February 3, 2015 Hi mate I am currently using magnum in my 243 under the 115 dtac. I don't know velocity as yet but I terms of group size it's very very good! Yeah I really like the powder mate. I'm going to be using 58gr Vmax. Thought the hunter was a slow powder but on their data it seems to give good results. Cheers Danny. Link to comment Share on other sites More sharing options...
Dac9976 Posted February 7, 2015 Author Report Share Posted February 7, 2015 Hi Ok need a bit of help fellas. Just started doing some loads with Ramshot hunter, using there data. Started to notice that the cases look really full so I put 50.5gr in a case( which is not max load) to see how full it would get.......right to the very top! Any ideas????? Cheers Danny.

mildot Posted February 7, 2015 Report Share Posted February 7, 2015 Use less Link to comment Share on other sites More sharing options...
mildot Posted February 7, 2015 Report Share Posted February 7, 2015 Different cases hold different amounts. I would start much lower as if the case is still fairly full you will still get the pressures but with less powder so could still get the fps you require! It's all trial and error Link to comment Share on other sites More sharing options...

It's all trial and error Ok might still give it a go. I tried the lowest amount stated and it still looked fairly full but doable. Why would they state 52 gr if it's physically impossible to put 52gr of powder in the case? Cheers Danny. Link to comment Share on other sites More sharing options...
mildot Posted February 7, 2015 Report Share Posted February 7, 2015 I had a .308 that I struggled to get 45gr of N140 in while others could get 46-48gr! Its all down to the cases. Some cases just simply have more room! As long as the powder doesn't go over the base of the neck you should be fine but I would drop down the powder so that you don't start load testing with a compressed load.

dannywayoflife Posted February 7, 2015 Report Share Posted February 7, 2015 Always start at a known published bottom load and work up in your rifle. Link to comment Share on other sites More sharing options...

Dac9976 Posted February 7, 2015 Author Report Share Posted February 7, 2015 Always start at a known published bottom load and work up in your rifle. My info was from a published bottom load, the case was nearly full with the bottom load hence my confusion. Cheers Danny. Link to comment Share on other sites More sharing options...

gbal Posted February 8, 2015 Report Share Posted February 8, 2015 Dac,as per mildot-brass cases vary between manufacturers,and occasionally within manufacturer.SAAMI specs are for the outside of the case,only. You won't be using any,but military brass is often quite different. To get some idea,look at Accurate Shooter site-243 is sketchy,though Norma has more than Lapua,Winchester more than Remington,but no detail. Have a look at 223-where there is a table of case weights-not the same as capacity,but indicates the possible variance-up to 2.5g. The relationship of volume/weight to case fill/compression is complex,so even more reason to work up-or down...if you have any signs of overfill. gbal Link to comment Share on other sites More sharing options...
Dac9976 Posted February 8, 2015 Author Report Share Posted February 8, 2015 Thanks for the info fellas, I feel a lot more confident now. I'll drop it right back and work up slowly:) Cheers Danny. Link to comment Share on other sites More sharing options...
Dac9976 Posted March 22, 2015 Author Report Share Posted March 22, 2015 Don't know if anyone's interested. Finally work up a load, 47.3gr of Ramshot hunter with a 58gr vmax doing 3450fps. Excellent group. Cheers Danny. Link to comment Share on other sites More sharing options...
