20in barrel velocity

[caleb90]

i was reviewing some of my data on my 100gr hand loads. 28.5 gr benchmark produced great groups and a sd of 4.1. velocity was 2642fps, seems kind of low seeing i was getting 2500fps from factory 123gr hornady black. just trying to decide of i should keep working higher or not.

You need a better powder like h335.

IMO,2642 FPS is not that low.And if you are getting great groups like you say,why change anything? I have a friend who uses CFE223. Is velocity is much higher but his groups aren’t worth a flip.What are you planning to do with those bullets?
I am using H335 w/90 gr speer TNT.Out of my Criterion 22” Hbar I am getting around 2770 FPS.My buddy told me I should max out my loads and get 2900fps.But why.?Higher velocity does not always mean better accuracy.My groups are 1/2” to 3/4” @ 100 yrds.For hunting hogs out to 150yrds it will more than suffice.
For me,accuracy is the goal.

100 grainers will be for target and hunting. h335 and benchmark at one after another on the burn chart, maybe id gain some thing by trying h335 or maybe not. just trying to pick your brains and see what yall think

I get an average of 2810 using 30.4 of H335 in my 20" PSA upper , with good groups at 100 yards .

It's hard to beat h335 with the 100 grain or less bullets. Maybe cfe223 could best it for speed but honestly I belive h335 will give you the highest speed on a accuracy node with 100 grain or less in weight bullets.

I broke 3000 fps with a 85 grain bullet in my howa bolt action 20 inch barrel with h335 but the groups weren't there. Backed it down to a cool 2882 average velocity and it's a tack driver.
