MikedaddyH Posted September 7, 2015 Report Posted September 7, 2015 Makes me want an AR pistol in 338FED.
Rsquared Posted September 7, 2015 Report Posted September 7, 2015 Once again. Nice build my man. Nice review too. That's a pretty impressive rifle. But I've been known to have an SBR thing. laughing
edgecrusher Posted September 7, 2015 Report Posted September 7, 2015 Once again. Nice build my man. Nice review too. That's a pretty impressive rifle. But I've been known to have an SBR thing. laughingI got to get mine off the ground..... Slacking big time, plus new bike is a money sponge
jeanclaudesegal Posted September 7, 2015 Author Report Posted September 7, 2015 thanx for commenting glad you fellers like it..I still got some more testing to do at 200yards..I will report back soon
GreyGoose Posted September 7, 2015 Report Posted September 7, 2015 Well if you miss em at least you'll scare em to death! Haha!Nice work young man. ;-)
jeanclaudesegal Posted September 7, 2015 Author Report Posted September 7, 2015 Thank you..I enjoy making these videos and sharing it here with all you good people....If anyone decides to build one like this please post your results and your reviews
jtallen83 Posted September 7, 2015 Report Posted September 7, 2015 Please send a note to the NRA to help the Iowa legislature get some new laws passed that will allow me to own a suppressed SBR, right now my P716 is as close as I can get.........damn that 338 looks like fun!

shepp Posted September 8, 2015 Report Posted September 8, 2015 I got to get mine off the ground..... Slacking big time, plus new bike is a money spongepiss poor excuse! Get your priorities straight man ;)
98Z5V Posted September 8, 2015 Report Posted September 8, 2015 Looks like the first 4 rounds - about 2200fps flat when it didn't knock the sunshade off - 30fps higher on the two rounds when the sunshade blew off - wondering if the concussion bouncing the sunshade off was the reason for the higher readings.Total deviation on the AE 185s?
survivalshop Posted September 8, 2015 Report Posted September 8, 2015 If your blowing your sun shades off , your Chrono is too close to your muzzle .I keep mine about ten feet away from Muzzle . The bullet probably already passed the sensors before the sun shade blew off .
jeanclaudesegal Posted September 8, 2015 Author Report Posted September 8, 2015 (edited) Believe it or not..the chrono was about 15ft away from me lol.. I guess i should have put it further .I dont believe the sunshade being knocked off had anything to do with the velocity change..I have seen this happen before to others and that does not change the consistencies if it is built back properly.The temp was a little warm that day..it could have been why i was getting a little higher readings..The previous time i shot into it, I only shot a string of 2..this time it was 4 of the 180gr nosler.. I tested my 50beo after to see if there were any inconsistencies from my previous test and the 50 beowulf 335gr was about 20fps faster than my previous test shooting a string of 5 shots..So in conclusion i believe the warmer weather does have something to do with slightly higher readings..On average i am getting a little over 2200fps with the 180gr noslers Edited September 8, 2015 by jeanclaudesegal
jeanclaudesegal Posted September 8, 2015 Author Report Posted September 8, 2015 Temp sensitive powders. could be..but i was getting similar results with my 50 beowulf..I think it has to do with the temp outside..
98Z5V Posted September 9, 2015 Report Posted September 9, 2015 ...and the temp outside would affect temp-sensitive powders.
MikedaddyH Posted September 9, 2015 Report Posted September 9, 2015 Like I said , Temp Sensitive Powders !Next time put some of the same rounds in a couple of zip lock bags and freeze them the night before then keep them in a cooler at the range till you shoot them ... The velocity will be slower !
jeanclaudesegal Posted September 9, 2015 Author Report Posted September 9, 2015 ...and the temp outside would affect temp-sensitive powders.Yeah thats kinda little above and beyond what i am gonna do to check cold-cool weather ballistics..I dont know how many ammunition companies like Federal and Alexander Arms use temp sensitive powders but i would think that there is reasons behind it....Here in south texas it is mostly hot throughout the year..i more than likely will expect to see the same chronograph readings that i am getting throughout most time of the year..I guess it is to my advantage that i get a faster bullet due to my weather here v.s somewhere up north where it is more cooler and dryer...What i will do though in december when it starts to cool down here in texas..i will take it out for another chronograph testing to see the velocity change and report back my results..
EasyEJL Posted September 9, 2015 Report Posted September 9, 2015 I'm surprised there wasn't more of a fireball
jeanclaudesegal Posted September 9, 2015 Author Report Posted September 9, 2015 I'm surprised there wasn't more of a fireballIll have to do a night shoot..i cant really see anything during the daytime..Same with my 50 beowulf SBR
MikedaddyH Posted September 9, 2015 Report Posted September 9, 2015 A 308 AR pistol throws a wicked fireball... So should the 338Fed. Shoot it at dusk, cool fireworks !
98Z5V Posted September 13, 2015 Report Posted September 13, 2015 jeanclaudevandammestevensegal - do you understand what temp sensitive powders are? From our replies-to your replies, it looks like you don't understand what we're talking about... in reference to temp-sensitive powders.
jeanclaudesegal Posted September 13, 2015 Author Report Posted September 13, 2015 (edited) jeanclaudevandammestevensegal - do you understand what temp sensitive powders are? From our replies-to your replies, it looks like you don't understand what we're talking about... in reference to temp-sensitive powders.Yes i do..The Statement.. Temp Sensitive powders Defines exactly what it means....Please read my previous post..I was wondering which other ammo manufacturing companies use temp sensitive powders......I have spoke to a few reloaders and some of them tell me that they know for certain that Alliant powders are the worst for increasing/decreasing in power released with changes of temperature, and the best one for not showing swings in power released are Hodgdon Extreme powders, most ball powders are stable until extreme cold/hot situations show themselves.
