Wmd the Big Beast 65 Creedmoor Superkit! Review

Most half-dozen.five Creedmoor shooters prefer heavier bullets.  I happen to be one of them.  While my favorite bullet for the Creedmoor is the 142 Sierra MatchKing (SMK), it'due south slightly lighter, and easier to stabilize little brother, the 140 SMK is also quite pop.

When they stand up side by side you'll notice the 140 SMK (above, left) is also slightly shorter than the 142 SMK (right).  This means the 140 will stabilize improve in slower twist barrels more than the 142 does; and you'll see initial factory 6.5 Creedmoor armament offerings in the 140 as opposed to the 142 because it tin can be fired through a larger multifariousness of rifles.  In this postal service I'll take a expect at how the 140 SMK performs in a gas gun with two pop powders, Varget and H4350.

For a examination gun I am using a WMD Guns Big Beast.  Known for their proprietary coatings, WMD Guns has manufactured rifles since 2011.

The 6.5 Creedmoor Big Creature features 7075 Aluminum Nib-X coated barracks upper and lower receivers, 20″ Match Course 1/viii″ twist push rifled 416 stainless steel barrel, Nib-X coated BCG, Hipertouch 24-E trigger, fixed modular stock with adaptable length of pull and cheekpiece and a low profile Thousand-LOK manus guard (Note this rifle doesn't accept a specially heavy butt).

For glass, I mounted a 3-15x50mm Nightforce F1 telescopic in a Spuhr mount (this one as well has an Aimpoint T1 on the side) that I ordered from Brownells.

Since this is a gas gun I decided to employ new Hornady brass with a CCI #200 primer under Varget powder.  All shooting was done prone from a bipod.  Velocity data was recorded with a MagnetoSpeed V3 barrel mounted ballistic chronograph.

Group sizes for the 140 SMK with Varget ranged from .777″ (.742) to 1.404″ (1.341 MOA) with an boilerplate 5-shot grouping size of 1.040″ (.993 MOA).  Despite the fact that 3 of the v loads tested were sub MOA, the Varget loads failed to reliably wheel the rifle. For this reason I would non recommend using Varget with 140 grain class bullets in a semi-automated half dozen.5 Creedmoor.

Group sizes for the 140 SMK with H4350 ranged from .651″ (.622 MOA) to ane.394″ (1.331 MOA) with an average 5-shot group size of ane.149″ (ane.097 MOA).   Only one of the five loads tested with H4350 provided sub MOA results, the 41.1 gr load, and that was quite impressive.  All of the H4350 loads cycled the rifle reliably.  If I were to select a 140 Grain load for this rifle, it would be that ane.

Between the 2 powders, average grouping size for the 140 SMK was 1.094″ (1.045 MOA).

NOTE: If yous are a regular reader y'all'll note that my target looks different.  I used to use i″ orangish dots on cardboard targets.  They worked in near conditions, nonetheless, in heavy pelting or extreme cold, the adhesive would fail and they would fall off the target.  I developed this target with Rite in the Rain.  It is on waterproof stock with true 1.047 MOA dark-green dots.  The color provides excellent contrast and you lot can still see your impacts on the paper.   Rite in the Rain sells these targets too as paper that you can print your ain targets on.   To learn more about Rite in the Pelting and their line of targets, click here.

Overall, I keep to be impressed with the performance of my WMD Big Beast chambered in 6.5 Creedmoor.  If you lot are in the market for a premium gas gun, bank check them out here.
