ThePestControllers Posted August 11, 2013 Report Share Posted August 11, 2013 The question arose after i looked at various loading manuals and noticed that there was a massive difference between powder loads for what is essentially look like very similar bullets. i refer to the Hornady 35gr V-Max and the Nosler 35 gr varmageddon,Now i know they are different but just how different they are both 35gr and minute difference in length of only .003" both .224" in the nosler data sheet it is giving a Lil,Gun powder load of Min 8gr to Max 10gr for the 35gr varmageddon and in the hodgdon data sheet is is giving for Lil,Gun powder min 12gr to a max of 13gr for the 35 gr v-Max Why is there so much difference between the the 2 sets of loading data powder charge (lil,gun) for what on the surface look like to very similar bullets.

kent Posted August 11, 2013 Report Share Posted August 11, 2013 Different bullets produce different pressures. To be honest as long as you are not touching the rifling (quite possible with non hornet specific bullets) LilGun is very safe. Touch the rifling and pressure in the chamber can rise dramatically, I have never tried to stick a 35v-max out the end of the case but I think it unlikely that you will have an issue in this regards - the Nosler? I am not so sure, this is maybe the reason they dropped the higher fill levels from the data. Quote Link to comment Share on other sites More sharing options...
Amazed Posted August 12, 2013 Report Share Posted August 12, 2013 Erring on the side of caution maybe ? Quote Link to comment Share on other sites More sharing options...
ThePestControllers Posted August 12, 2013 Author Report Share Posted August 12, 2013 theres obviously a reason but i just didn't know what it was maybe that .003" makes all the difference. not that i am going to start messing around with figures given out by reputable data its just i am curious. cheers Daz Quote Link to comment Share on other sites More sharing options...
Amazed Posted August 12, 2013 Report Share Posted August 12, 2013 I have had a similar experience when I was messing with n110 I have 3 sets of data all from vit all different :( lee data was also different lmao Quote Link to comment Share on other sites More sharing options...
ThePestControllers Posted August 12, 2013 Author Report Share Posted August 12, 2013 so what accounts for these differences. what would happen if the hodgdon data said 12-13g 35g v-max and i put 10g in. knowing that a very similar bullet says 8-10g. this is only asking questions wanting to learn not being stupid or irresponsible. has anyone tried different weights of powder differing from manufacturers data. and what were the results Cheers Daz Quote Link to comment Share on other sites More sharing options...
Amazed Posted August 12, 2013 Report Share Posted August 12, 2013 Ye all the time A lot of data for the hornet is based around the serria 45 grain hornet I fire the hornady hornet until they run out :( so some adaption has to be made. Take the new loads I am working up for example Book said 45 grain serria 11.5 grains 300 mp fed 205 primer. Winchester brass -5% or 10% if your really twitchy. swap the bullet for hornady hornet. The primer to rem 6 1/2 srp And the brass is new neck sized flash holes cleaned up and a small flare on the case to aid seating. ppu brass. Tested @ 150 yards 5 shots at each weight. Started seeing results @ 11.2 grains 1.5 inch 11.3 same under 1 inch closer to .5 in fact two of the 5 were in the same hole. ha ha No pressure signs at all the brass is still clean I have loaded the same with 7 1/2 brp but haven't seen anything to outdo the 6 1/2 maybe it will come into its own later on with denser loads. Some more to test over the next few days up to 11.6 grain. Just stop when you see something suspect. Little changes big results. To be honest with you I would run the test loads you have done and build your confidence and knowledge as you go. Karl. Quote Link to comment Share on other sites More sharing options...
ThePestControllers Posted August 12, 2013 Author Report Share Posted August 12, 2013 cheers karl was 11.5 supposed to be the max for your load Quote Link to comment Share on other sites More sharing options...
Amazed Posted August 12, 2013 Report Share Posted August 12, 2013 cheers karl was 11.5 supposed to be the max for your load Yes that's the stated book load to be worked up to. Maybe a bit beyond but not at the expense of consistency. Speed isn't everything. Will see what the results bring. Karl. Quote Link to comment Share on other sites More sharing options...
kent Posted August 12, 2013 Report Share Posted August 12, 2013 (edited) Listen forget what the book says the max is, your gun might not handle the max should always be the thought with any gun. One should just work a load up using best practice and a sensible start load (with a proper length round for your chamber). In fairness if everything else is good (and this is critical) I doubt you could over pressure a hornet case by putting too much LilGun in, fact is velocity and fill levels are weird with this stuff look at this 40 grn v-max 1.845 COL Hornady Brass LilGun 11grn=2950fps 11.2=2890 11.4=2830 11.6=2824 11.8=2844 12grn=2927 12.2=2919 12.4=2923 Note fastest velocity recorded at lowest fill, yet no radical gains or losses through the test.

ThePestControllers Posted August 12, 2013 Author Report Share Posted August 12, 2013 which of these loads shot best or did you mean they were very similar with nothing to choose between them. have you done similar tests with the 35gr v-max Quote Link to comment Share on other sites More sharing options...
kent Posted August 13, 2013 Report Share Posted August 13, 2013 which of these loads shot best or did you mean they were very similar with nothing to choose between them. have you done similar tests with the 35gr v-max My point is load fill should only be looked on in terms of standard deviation and accuracy. What works best in mine is no guarantee about yours- you have to play with the variables. Yes I have and I don't like it much, stunning at 50 yds, ok at 100 yds then really starts to let go, its got an awful BC and at 200 yds it wasn't even worth aiming Quote Link to comment Share on other sites More sharing options...
