How does the difference in case capacity affect pressure?

Re: iFire's PS90 Load Data

Yep with 1x brass it is. The 35gr VG has a long shank for weight, meaning more bullet in contact with rifling, so you can't push it as fast as a same wight or even slightly heavier bullet with less shank. fantastic, guess it is time to start playing with other bullets then. I wanted some 55g sub so...

Re: iFire's PS90 Load Data

I think I have pretty descent FPS with 36g Barnes Varmint Grenades and 5.5 grains of AutoComp. Last batch was 2320 out of a 16 inch barreled bolt action. Does that seem on par with what others are getting from that barrel length or should I be getting faster? 1x fired FN Brass CCI 400 small rifle pr...

Re: 5.7x28 bolt action

Thanks, hope to get it dialed in really tight soon. Will keep updates coming in as well with handloads, I should be able to get pretty fast.

Re: 5.7x28 bolt action

Well if I had to pin a number to it lets see if I can add it up. I am just a simple Arkansas man so will take my shoes off real quick. Donor gun= 280 Bolt= 250 Barrel= 470 Trigger= 125 Magazine(yeah you read correct, it is not a bobsled gun, it actually holds ammo and feeds them =-0) Trade for an Ti...

Re: 5.7x28 bolt action

So update on the 27 grain bullet problem. Turns out it might have been a range problem(my range looks like a jungle at the moment), there were a few blades of tall grass in front of my target and I believe the bullet was hitting those and starting to tumble. I could be wrong but a fast moving small ...

Re: 5.7x28 bolt action

5.7 uses the same bullets as .223. So ANY .223/5.56 rifled barrel will work for it. Keyholing is normally an issue with too heavy a bullet and a long twist like 1:14. NOT the other way around. Who the hell thought 1:14 was a good twist rate for a .223 round that likes lighter bullets? What are the ...

Re: 5.7x28 bolt action

Hopefully this topic isn't completely forgotten about. Just curious if anyone here that has a bolt action 5.7 has had any issues with the 27 grain factory fn ammo? My 1:14 Shilleen barrel doesn't seem to like it, it keyholes every round.
