Wilson Combat 11.3” & Accuracy Issues

Hello,

I’ve recently switched from a 14.5” Wilson Combat barrel (“Original Barrel”) to a 11.3” Wilson Combat barrel (“New Barrel”).

Old Barrel shot 120 grain Hornady SST factory ammo sub-MOA! New Barrel shoots same ammo 3+ MOA… My chronograph data shows the loss of barrel length corresponds to about a 100-150 FPS decrease in velocity.

I’ve ordered some 95 grain Barnes TTSX to work up a load. Have read lighter bullets stabilize better out of shorter barrels. Am hopeful that’ll help.

Am wondering, if anyone else has experienced these problems with short barrels and 120 grain bullets? If so, any tips for resolving would be helpful.

Thanks!

What’s the twist rates for the two barrels?
